+ * - `i` is ISO day of week. For `i` and `ii` is returns numeric ISO week days,
+ *   i.e. 7 for Sunday, 1 for Monday, etc.
+ * - `I` is ISO week of year, as opposed to `w` which is local week of year.
+ * - `R` is ISO week-numbering year, as opposed to `Y` which is local week-numbering year.
+ *   `R` is supposed to be used in conjunction with `I` and `i`
+ *   for universal ISO week-numbering date, whereas
+ *   `Y` is supposed to be used in conjunction with `w` and `e`
+ *   for week-numbering date specific to the locale.
+ * - `P` is long localized date format
+ * - `p` is long localized time format

+ * @throws {TypeError} 2 arguments required

+/**
+ * @name areIntervalsOverlapping
+ * @category Interval Helpers
+ * @summary Is the given time interval overlapping with another time interval?
+ *
+ * @description
+ * Is the given time interval overlapping with another time interval? Adjacent intervals do not count as overlapping.
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `areRangesOverlapping` to `areIntervalsOverlapping`.
+ *   This change was made to mirror the use of the word "interval" in standard ISO 8601:2004 terminology:
+ *
+ *   ```
+ *   2.1.3
+ *   time interval
+ *   part of the time axis limited by two instants
+ *   ```
+ *
+ *   Also, this function now accepts an object with `start` and `end` properties
+ *   instead of two arguments as an interval.
+ *   This function now throws `RangeError` if the start of the interval is after its end
+ *   or if any date in the interval is `Invalid Date`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   areRangesOverlapping(
+ *     new Date(2014, 0, 10), new Date(2014, 0, 20),
+ *     new Date(2014, 0, 17), new Date(2014, 0, 21)
+ *   )
+ *
+ *   // v2.0.0 onward
+ *
+ *   areIntervalsOverlapping(
+ *     { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *     { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
+ *   )
+ *   ```
+ *
+ * @param {Interval} intervalLeft - the first interval to compare. See [Interval]{@link https://date-fns.org/docs/Interval}
+ * @param {Interval} intervalRight - the second interval to compare. See [Interval]{@link https://date-fns.org/docs/Interval}
+ * @param {Object} [options] - the object with options
+ * @param {Boolean} [options.inclusive=false] - whether the comparison is inclusive or not
+ * @returns {Boolean} whether the time intervals are overlapping
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} The start of an interval cannot be after its end
+ * @throws {RangeError} Date in interval cannot be `Invalid Date`
+ *
+ * @example
+ * // For overlapping time intervals:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
+ * )
+ * //=> true
+ *
+ * @example
+ * // For non-overlapping time intervals:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 21), end: new Date(2014, 0, 22) }
+ * )
+ * //=> false
+ *
+ * @example
+ * // For adjacent time intervals:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 30) }
+ * )
+ * //=> false
+ *
+ * @example
+ * // Using the inclusive option:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) }
+ * )
+ * //=> false
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) },
+ *   { inclusive: true }

+ * @name differenceInDays
+ * @category Day Helpers
+ * @summary Get the number of full days between the given dates.
+ *
+ * @description
+ * Get the number of full day periods between two dates. Fractional days are
+ * truncated towards zero.
+ *
+ * One "full day" is the distance between a local time in one day to the same
+ * local time on the next or previous day. A full day can sometimes be less than
+ * or more than 24 hours if a daylight savings change happens between two dates.
+ *
+ * To ignore DST and only measure exact 24-hour periods, use this instead:
+ * `Math.floor(differenceInHours(dateLeft, dateRight)/24)|0`.
+ *
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * @param {Date|Number} dateLeft - the later date
+ * @param {Date|Number} dateRight - the earlier date
+ * @returns {Number} the number of full days according to the local timezone
+ * @throws {TypeError} 2 arguments required
+ *
+ * @example
+ * // How many full days are between
+ * // 2 July 2011 23:00:00 and 2 July 2012 00:00:00?
+ * const result = differenceInDays(

+ * @description
+ * Get the number of full weeks between two dates. Fractional weeks are
+ * truncated towards zero.
+ *
+ * One "full week" is the distance between a local time in one day to the same
+ * local time 7 days earlier or later. A full week can sometimes be less than
+ * or more than 7*24 hours if a daylight savings change happens between two dates.
+ *
+ * To ignore DST and only measure exact 7*24-hour periods, use this instead:
+ * `Math.floor(differenceInHours(dateLeft, dateRight)/(7*24))|0`.
+ *
+ *
+ * ### v2.0.0 breaking changes:

+ *
+ * @param {Date|Number} dateLeft - the later date
+ * @param {Date|Number} dateRight - the earlier date
+ * @returns {Number} the number of full weeks

+ * // 1 March 2020 0:00 and 6 June 2020 0:00 ?
+ * // Note: because local time is used, the

+/**
+ * @name eachDayOfInterval
+ * @category Interval Helpers
+ * @summary Return the array of dates within the specified time interval.
+ *
+ * @description
+ * Return the array of dates within the specified time interval.
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `eachDay` to `eachDayOfInterval`.
+ *   This change was made to mirror the use of the word "interval" in standard ISO 8601:2004 terminology:
+ *
+ *   ```
+ *   2.1.3
+ *   time interval
+ *   part of the time axis limited by two instants
+ *   ```
+ *
+ *   Also, this function now accepts an object with `start` and `end` properties
+ *   instead of two arguments as an interval.
+ *   This function now throws `RangeError` if the start of the interval is after its end
+ *   or if any date in the interval is `Invalid Date`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   eachDay(new Date(2014, 0, 10), new Date(2014, 0, 20))
+ *
+ *   // v2.0.0 onward
+ *
+ *   eachDayOfInterval(
+ *     { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) }
+ *   )
+ *   ```
+ *
+ * @param {Interval} interval - the interval. See [Interval]{@link https://date-fns.org/docs/Interval}
+ * @param {Object} [options] - an object with options.
+ * @param {Number} [options.step=1] - the step to increment by. The value should be more than 1.
+ * @returns {Date[]} the array with starts of days from the day of the interval start to the day of the interval end
+ * @throws {TypeError} 1 argument required
+ * @throws {RangeError} `options.step` must be a number greater than 1
+ * @throws {RangeError} The start of an interval cannot be after its end
+ * @throws {RangeError} Date in interval cannot be `Invalid Date`
+ *
+ * @example
+ * // Each day between 6 October 2014 and 10 October 2014:
+ * const result = eachDayOfInterval({
+ *   start: new Date(2014, 9, 6),
+ *   end: new Date(2014, 9, 10)
+ * })
+ * //=> [
+ * //   Mon Oct 06 2014 00:00:00,
+ * //   Tue Oct 07 2014 00:00:00,
+ * //   Wed Oct 08 2014 00:00:00,
+ * //   Thu Oct 09 2014 00:00:00,
+ * //   Fri Oct 10 2014 00:00:00
+ * // ]

+ * @summary Format the date.
+ *
+ * @description
+ * Return the formatted date string in the given format. The result may vary by locale.
+ *
+ * > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
+ * > See: https://git.io/fxCyr
+ *
+ * The characters wrapped between two single quotes characters (') are escaped.
+ * Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
+ * (see the last example)
+ *
+ * Format of the string is based on Unicode Technical Standard #35:
+ * https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
+ * with a few additions (see note 7 below the table).

+ * Notes:
+ * 1. "Formatting" units (e.g. formatting quarter) in the default en-US locale
+ *    are the same as "stand-alone" units, but are different in some languages.
+ *    "Formatting" units are declined according to the rules of the language
+ *    in the context of a date. "Stand-alone" units are always nominative singular:
+ *
+ *    `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`
+ *
+ *    `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`
+ *
+ * 2. Any sequence of the identical letters is a pattern, unless it is escaped by
+ *    the single quote characters (see below).
+ *    If the sequence is longer than listed in table (e.g. `EEEEEEEEEEE`)
+ *    the output will be the same as default pattern for this unit, usually
+ *    the longest one (in case of ISO weekdays, `EEEE`). Default patterns for units
+ *    are marked with "2" in the last column of the table.
+ *
+ *    `format(new Date(2017, 10, 6), 'MMM') //=> 'Nov'`
+ *
+ *    `format(new Date(2017, 10, 6), 'MMMM') //=> 'November'`
+ *
+ *    `format(new Date(2017, 10, 6), 'MMMMM') //=> 'N'`
+ *
+ *    `format(new Date(2017, 10, 6), 'MMMMMM') //=> 'November'`
+ *
+ *    `format(new Date(2017, 10, 6), 'MMMMMMM') //=> 'November'`
+ *
+ * 3. Some patterns could be unlimited length (such as `yyyyyyyy`).
+ *    The output will be padded with zeros to match the length of the pattern.
+ *
+ *    `format(new Date(2017, 10, 6), 'yyyyyyyy') //=> '00002017'`
+ *
+ * 4. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.
+ *    These tokens represent the shortest form of the quarter.
+ *
+ * 5. The main difference between `y` and `u` patterns are B.C. years:
+ *
+ *    | Year | `y` | `u` |
+ *    |------|-----|-----|
+ *    | AC 1 |   1 |   1 |
+ *    | BC 1 |   1 |   0 |
+ *    | BC 2 |   2 |  -1 |
+ *
+ *    Also `yy` always returns the last two digits of a year,
+ *    while `uu` pads single digit years to 2 characters and returns other years unchanged:
+ *
+ *    | Year | `yy` | `uu` |
+ *    |------|------|------|
+ *    | 1    |   01 |   01 |
+ *    | 14   |   14 |   14 |
+ *    | 376  |   76 |  376 |
+ *    | 1453 |   53 | 1453 |
+ *
+ *    The same difference is true for local and ISO week-numbering years (`Y` and `R`),
+ *    except local week-numbering years are dependent on `options.weekStartsOn`
+ *    and `options.firstWeekContainsDate` (compare [getISOWeekYear]{@link https://date-fns.org/docs/getISOWeekYear}
+ *    and [getWeekYear]{@link https://date-fns.org/docs/getWeekYear}).
+ *
+ * 6. Specific non-location timezones are currently unavailable in `date-fns`,
+ *    so right now these tokens fall back to GMT timezones.
+ *
+ * 7. These patterns are not in the Unicode Technical Standard #35:
+ *    - `i`: ISO day of week
+ *    - `I`: ISO week of year
+ *    - `R`: ISO week-numbering year
+ *    - `t`: seconds timestamp
+ *    - `T`: milliseconds timestamp
+ *    - `o`: ordinal number modifier
+ *    - `P`: long localized date
+ *    - `p`: long localized time
+ *
+ * 8. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.
+ *    You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://git.io/fxCyr
+ *
+ * 9. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.
+ *    You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://git.io/fxCyr
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The second argument is now required for the sake of explicitness.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *   format(new Date(2016, 0, 1))
+ *
+ *   // v2.0.0 onward
+ *   format(new Date(2016, 0, 1), "yyyy-MM-dd'T'HH:mm:ss.SSSxxx")
+ *   ```
+ *
+ * - New format string API for `format` function
+ *   which is based on [Unicode Technical Standard #35](https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table).
+ *   See [this post](https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg) for more details.
+ *
+ * - Characters are now escaped using single quote symbols (`'`) instead of square brackets.
+ *
+ * @param {Date|Number} date - the original date
+ * @param {String} format - the string of tokens
+ * @param {Object} [options] - an object with options.

+ * @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
+ * @param {Number} [options.firstWeekContainsDate=1] - the day of January, which is
+ * @param {Boolean} [options.useAdditionalWeekYearTokens=false] - if true, allows usage of the week-numbering year tokens `YY` and `YYYY`;

+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `distanceInWords ` to `formatDistance`
+ *   to make its name consistent with `format` and `formatRelative`.
+ *
+ * - The order of arguments is swapped to make the function
+ *   consistent with `differenceIn...` functions.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   distanceInWords(
+ *     new Date(1986, 3, 4, 10, 32, 0),
+ *     new Date(1986, 3, 4, 11, 32, 0),
+ *     { addSuffix: true }
+ *   ) //=> 'in about 1 hour'
+ *
+ *   // v2.0.0 onward
+ *
+ *   formatDistance(
+ *     new Date(1986, 3, 4, 11, 32, 0),
+ *     new Date(1986, 3, 4, 10, 32, 0),
+ *     { addSuffix: true }
+ *   ) //=> 'in about 1 hour'
+ *   ```
+ *
+ * @param {Date|Number} date - the date
+ * @param {Date|Number} baseDate - the date to compare with
+ * @param {Object} [options] - an object with options.
+ * @param {Boolean} [options.includeSeconds=false] - distances less than a minute are more detailed
+ * @param {Boolean} [options.addSuffix=false] - result indicates if the second date is earlier or later than the first
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @returns {String} the distance in words
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} `date` must not be Invalid Date
+ * @throws {RangeError} `baseDate` must not be Invalid Date
+ * @throws {RangeError} `options.locale` must contain `formatDistance` property
+ *
+ * @example
+ * // What is the distance between 2 July 2014 and 1 January 2015?
+ * const result = formatDistance(new Date(2014, 6, 2), new Date(2015, 0, 1))
+ * //=> '6 months'
+ *
+ * @example
+ * // What is the distance between 1 January 2015 00:00:15
+ * // and 1 January 2015 00:00:00, including seconds?
+ * const result = formatDistance(
+ *   new Date(2015, 0, 1, 0, 0, 15),
+ *   new Date(2015, 0, 1, 0, 0, 0),
+ *   { includeSeconds: true }
+ * )
+ * //=> 'less than 20 seconds'
+ *
+ * @example
+ * // What is the distance from 1 January 2016
+ * // to 1 January 2015, with a suffix?
+ * const result = formatDistance(new Date(2015, 0, 1), new Date(2016, 0, 1), {
+ *   addSuffix: true
+ * })
+ * //=> 'about 1 year ago'
+ *
+ * @example
+ * // What is the distance between 1 August 2016 and 1 January 2015 in Esperanto?
+ * import { eoLocale } from 'date-fns/locale/eo'
+ * const result = formatDistance(new Date(2016, 7, 1), new Date(2015, 0, 1), {

+ *
+ * @description
+ * Return the distance between the given dates in words, using strict units.
+ * This is like `formatDistance`, but does not use helpers like 'almost', 'over',
+ * 'less than' and the like.
+ *
+ * | Distance between dates | Result              |
+ * |------------------------|---------------------|
+ * | 0 ... 59 secs          | [0..59] seconds     |
+ * | 1 ... 59 mins          | [1..59] minutes     |

+ * | 1 ... N years          | [1..N]  years       |
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `distanceInWordsStrict` to `formatDistanceStrict`
+ *   to make its name consistent with `format` and `formatRelative`.
+ *
+ * - The order of arguments is swapped to make the function
+ *   consistent with `differenceIn...` functions.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   distanceInWordsStrict(
+ *     new Date(2015, 0, 2),
+ *     new Date(2014, 6, 2)
+ *   ) //=> '6 months'
+ *
+ *   // v2.0.0 onward
+ *
+ *   formatDistanceStrict(
+ *     new Date(2014, 6, 2),
+ *     new Date(2015, 0, 2)
+ *   ) //=> '6 months'
+ *   ```
+ *
+ * - `partialMethod` option is renamed to `roundingMethod`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   distanceInWordsStrict(
+ *     new Date(1986, 3, 4, 10, 32, 0),
+ *     new Date(1986, 3, 4, 10, 33, 1),
+ *     { partialMethod: 'ceil' }
+ *   ) //=> '2 minutes'
+ *
+ *   // v2.0.0 onward
+ *
+ *   formatDistanceStrict(
+ *     new Date(1986, 3, 4, 10, 33, 1),
+ *     new Date(1986, 3, 4, 10, 32, 0),
+ *     { roundingMethod: 'ceil' }
+ *   ) //=> '2 minutes'
+ *   ```
+ *
+ * - If `roundingMethod` is not specified, it now defaults to `round` instead of `floor`.
+ *
+ * - `unit` option now accepts one of the strings:
+ *   'second', 'minute', 'hour', 'day', 'month' or 'year' instead of 's', 'm', 'h', 'd', 'M' or 'Y'
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   distanceInWordsStrict(
+ *     new Date(1986, 3, 4, 10, 32, 0),
+ *     new Date(1986, 3, 4, 10, 33, 1),
+ *     { unit: 'm' }
+ *   )
+ *
+ *   // v2.0.0 onward
+ *
+ *   formatDistanceStrict(
+ *     new Date(1986, 3, 4, 10, 33, 1),
+ *     new Date(1986, 3, 4, 10, 32, 0),
+ *     { unit: 'minute' }
+ *   )
+ *   ```
+ *
+ * @param {Date|Number} date - the date
+ * @param {Date|Number} baseDate - the date to compare with
+ * @param {Object} [options] - an object with options.
+ * @param {Boolean} [options.addSuffix=false] - result indicates if the second date is earlier or later than the first
+ * @param {'second'|'minute'|'hour'|'day'|'month'|'year'} [options.unit] - if specified, will force a unit
+ * @param {'floor'|'ceil'|'round'} [options.roundingMethod='round'] - which way to round partial units
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @returns {String} the distance in words
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} `date` must not be Invalid Date
+ * @throws {RangeError} `baseDate` must not be Invalid Date
+ * @throws {RangeError} `options.roundingMethod` must be 'floor', 'ceil' or 'round'
+ * @throws {RangeError} `options.unit` must be 'second', 'minute', 'hour', 'day', 'month' or 'year'
+ * @throws {RangeError} `options.locale` must contain `formatDistance` property
+ *
+ * @example
+ * // What is the distance between 2 July 2014 and 1 January 2015?
+ * const result = formatDistanceStrict(new Date(2014, 6, 2), new Date(2015, 0, 2))
+ * //=> '6 months'
+ *
+ * @example
+ * // What is the distance between 1 January 2015 00:00:15
+ * // and 1 January 2015 00:00:00?

+ *   unit: 'minute'
+ * })
+ * //=> '525600 minutes'
+ *
+ * @example
+ * // What is the distance from 1 January 2015
+ * // to 28 January 2015, in months, rounded up?
+ * const result = formatDistanceStrict(new Date(2015, 0, 28), new Date(2015, 0, 1), {
+ *   unit: 'month',
+ *   roundingMethod: 'ceil'
+ * })
+ * //=> '1 month'
+ *
+ * @example
+ * // What is the distance between 1 August 2016 and 1 January 2015 in Esperanto?
+ * import { eoLocale } from 'date-fns/locale/eo'
+ * const result = formatDistanceStrict(new Date(2016, 7, 1), new Date(2015, 0, 1), {

+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `distanceInWordsToNow ` to `formatDistanceToNow`
+ *   to make its name consistent with `format` and `formatRelative`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   distanceInWordsToNow(new Date(2014, 6, 2), { addSuffix: true })
+ *   //=> 'in 6 months'
+ *
+ *   // v2.0.0 onward
+ *
+ *   formatDistanceToNow(new Date(2014, 6, 2), { addSuffix: true })
+ *   //=> 'in 6 months'
+ *   ```
+ *
+ * @param {Date|Number} date - the given date
+ * @param {Object} [options] - the object with options
+ * @param {Boolean} [options.includeSeconds=false] - distances less than a minute are more detailed
+ * @param {Boolean} [options.addSuffix=false] - result specifies if now is earlier or later than the passed date
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @returns {String} the distance in words
+ * @throws {TypeError} 1 argument required
+ * @throws {RangeError} `date` must not be Invalid Date
+ * @throws {RangeError} `options.locale` must contain `formatDistance` property
+ *
+ * @example
+ * // If today is 1 January 2015, what is the distance to 2 July 2014?
+ * var result = formatDistanceToNow(
+ *   new Date(2014, 6, 2)
+ * )
+ * //=> '6 months'
+ *
+ * @example
+ * // If now is 1 January 2015 00:00:00,
+ * // what is the distance to 1 January 2015 00:00:15, including seconds?
+ * var result = formatDistanceToNow(
+ *   new Date(2015, 0, 1, 0, 0, 15),
+ *   {includeSeconds: true}
+ * )
+ * //=> 'less than 20 seconds'
+ *
+ * @example
+ * // If today is 1 January 2015,
+ * // what is the distance to 1 January 2016, with a suffix?
+ * var result = formatDistanceToNow(
+ *   new Date(2016, 0, 1),
+ *   {addSuffix: true}
+ * )
+ * //=> 'in about 1 year'
+ *
+ * @example
+ * // If today is 1 January 2015,
+ * // what is the distance to 1 August 2016 in Esperanto?
+ * var eoLocale = require('date-fns/locale/eo')
+ * var result = formatDistanceToNow(
+ *   new Date(2016, 7, 1),
+ *   {locale: eoLocale}
+ * )
+ * //=> 'pli ol 1 jaro'

+ *
+ * @description
+ * Get the number of days that overlap in two time intervals
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `getOverlappingDaysInRanges` to `getOverlappingDaysInIntervals`.
+ *   This change was made to mirror the use of the word "interval" in standard ISO 8601:2004 terminology:
+ *
+ *   ```
+ *   2.1.3
+ *   time interval
+ *   part of the time axis limited by two instants
+ *   ```
+ *
+ *   Also, this function now accepts an object with `start` and `end` properties
+ *   instead of two arguments as an interval.
+ *   This function now throws `RangeError` if the start of the interval is after its end
+ *   or if any date in the interval is `Invalid Date`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   getOverlappingDaysInRanges(
+ *     new Date(2014, 0, 10), new Date(2014, 0, 20),
+ *     new Date(2014, 0, 17), new Date(2014, 0, 21)
+ *   )
+ *
+ *   // v2.0.0 onward
+ *
+ *   getOverlappingDaysInIntervals(
+ *     { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *     { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
+ *   )
+ *   ```
+ *
+ * @param {Interval} intervalLeft - the first interval to compare. See [Interval]{@link docs/Interval}
+ * @param {Interval} intervalRight - the second interval to compare. See [Interval]{@link docs/Interval}
+ * @returns {Number} the number of days that overlap in two time intervals
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} The start of an interval cannot be after its end
+ * @throws {RangeError} Date in interval cannot be `Invalid Date`
+ *
+ * @example
+ * // For overlapping time intervals adds 1 for each started overlapping day:
+ * getOverlappingDaysInIntervals(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
+ * )
+ * //=> 3
+ *
+ * @example
+ * // For non-overlapping time intervals returns 0:
+ * getOverlappingDaysInIntervals(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 21), end: new Date(2014, 0, 22) }
+ * )
+ * //=> 0

+ *
+ * > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
+ * > See: https://git.io/fxCyr
+ *
+ * The characters in the format string wrapped between two single quotes characters (') are escaped.
+ * Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
+ *
+ * Format of the format string is based on Unicode Technical Standard #35:
+ * https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
+ * with a few additions (see note 5 below the table).
+ *
+ * Not all tokens are compatible. Combinations that don't make sense or could lead to bugs are prohibited
+ * and will throw `RangeError`. For example usage of 24-hour format token with AM/PM token will throw an exception:
+ *
+ * ```javascript
+ * isMatch('23 AM', 'HH a')
+ * //=> RangeError: The format string mustn't contain `HH` and `a` at the same time
+ * ```
+ *
+ * See the compatibility table: https://docs.google.com/spreadsheets/d/e/2PACX-1vQOPU3xUhplll6dyoMmVUXHKl_8CRDs6_ueLmex3SoqwhuolkuN3O05l4rqx5h1dKX8eb46Ul-CCSrq/pubhtml?gid=0&single=true

+ * Notes:
+ * 1. "Formatting" units (e.g. formatting quarter) in the default en-US locale
+ *    are the same as "stand-alone" units, but are different in some languages.
+ *    "Formatting" units are declined according to the rules of the language
+ *    in the context of a date. "Stand-alone" units are always nominative singular.
+ *    In `format` function, they will produce different result:
+ *
+ *    `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`
+ *
+ *    `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`
+ *
+ *    `isMatch` will try to match both formatting and stand-alone units interchangably.
+ *
+ * 2. Any sequence of the identical letters is a pattern, unless it is escaped by
+ *    the single quote characters (see below).
+ *    If the sequence is longer than listed in table:
+ *    - for numerical units (`yyyyyyyy`) `isMatch` will try to match a number
+ *      as wide as the sequence
+ *    - for text units (`MMMMMMMM`) `isMatch` will try to match the widest variation of the unit.
+ *      These variations are marked with "2" in the last column of the table.
+ *
+ * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.
+ *    These tokens represent the shortest form of the quarter.
+ *
+ * 4. The main difference between `y` and `u` patterns are B.C. years:
+ *
+ *    | Year | `y` | `u` |
+ *    |------|-----|-----|
+ *    | AC 1 |   1 |   1 |
+ *    | BC 1 |   1 |   0 |
+ *    | BC 2 |   2 |  -1 |
+ *
+ *    Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`:
+ *
+ *    `isMatch('50', 'yy') //=> true`
+ *
+ *    `isMatch('75', 'yy') //=> true`
+ *
+ *    while `uu` will use the year as is:
+ *
+ *    `isMatch('50', 'uu') //=> true`
+ *
+ *    `isMatch('75', 'uu') //=> true`
+ *
+ *    The same difference is true for local and ISO week-numbering years (`Y` and `R`),
+ *    except local week-numbering years are dependent on `options.weekStartsOn`
+ *    and `options.firstWeekContainsDate` (compare [setISOWeekYear]{@link https://date-fns.org/docs/setISOWeekYear}
+ *    and [setWeekYear]{@link https://date-fns.org/docs/setWeekYear}).
+ *
+ * 5. These patterns are not in the Unicode Technical Standard #35:
+ *    - `i`: ISO day of week
+ *    - `I`: ISO week of year
+ *    - `R`: ISO week-numbering year
+ *    - `o`: ordinal number modifier
+ *    - `P`: long localized date
+ *    - `p`: long localized time
+ *
+ * 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.
+ *    You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://git.io/fxCyr
+ *
+ * 7. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.
+ *    You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://git.io/fxCyr
+ *
+ * 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based
+ *    on the given locale.
+ *
+ *    using `en-US` locale: `P` => `MM/dd/yyyy`
+ *    using `en-US` locale: `p` => `hh:mm a`
+ *    using `pt-BR` locale: `P` => `dd/MM/yyyy`
+ *    using `pt-BR` locale: `p` => `HH:mm`
+ *
+ * Values will be checked in the descending order of its unit's priority.
+ * Units of an equal priority overwrite each other in the order of appearance.
+ *
+ * If no values of higher priority are matched (e.g. when matching string 'January 1st' without a year),
+ * the values will be taken from today's using `new Date()` date which works as a context of parsing.
+ *
+ * The result may vary by locale.
+ *
+ * If `formatString` matches with `dateString` but does not provides tokens, `referenceDate` will be returned.
+ *
+ *
+ *
+ * @param {String} dateString - the date string to verify
+ * @param {String} formatString - the string of tokens
+ * @param {Object} [options] - an object with options.
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
+ * @param {1|2|3|4|5|6|7} [options.firstWeekContainsDate=1] - the day of January, which is always in the first week of the year
+ * @param {Boolean} [options.useAdditionalWeekYearTokens=false] - if true, allows usage of the week-numbering year tokens `YY` and `YYYY`;
+ *   see: https://git.io/fxCyr
+ * @param {Boolean} [options.useAdditionalDayOfYearTokens=false] - if true, allows usage of the day of year tokens `D` and `DD`;
+ *   see: https://git.io/fxCyr
+ * @returns {Boolean}
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} `options.weekStartsOn` must be between 0 and 6
+ * @throws {RangeError} `options.firstWeekContainsDate` must be between 1 and 7
+ * @throws {RangeError} `options.locale` must contain `match` property
+ * @throws {RangeError} use `yyyy` instead of `YYYY` for formatting years; see: https://git.io/fxCyr
+ * @throws {RangeError} use `yy` instead of `YY` for formatting years; see: https://git.io/fxCyr

+ * @throws {RangeError} use `dd` instead of `DD` for formatting days of the month; see: https://git.io/fxCyr
+ * @throws {RangeError} format string contains an unescaped latin alphabet character

+ * Returns false if argument is Invalid Date and true otherwise.
+ * Argument is converted to Date using `toDate`. See [toDate]{@link https://date-fns.org/docs/toDate}
+ * Invalid Date is a Date, whose time value is NaN.
+ *

+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - Now `isValid` doesn't throw an exception
+ *   if the first argument is not an instance of Date.
+ *   Instead, argument is converted beforehand using `toDate`.
+ *
+ *   Examples:
+ *
+ *   | `isValid` argument        | Before v2.0.0 | v2.0.0 onward |
+ *   |---------------------------|---------------|---------------|
+ *   | `new Date()`              | `true`        | `true`        |
+ *   | `new Date('2016-01-01')`  | `true`        | `true`        |
+ *   | `new Date('')`            | `false`       | `false`       |
+ *   | `new Date(1488370835081)` | `true`        | `true`        |
+ *   | `new Date(NaN)`           | `false`       | `false`       |
+ *   | `'2016-01-01'`            | `TypeError`   | `false`       |
+ *   | `''`                      | `TypeError`   | `false`       |
+ *   | `1488370835081`           | `TypeError`   | `true`        |
+ *   | `NaN`                     | `TypeError`   | `false`       |
+ *
+ *   We introduce this change to make *date-fns* consistent with ECMAScript behavior
+ *   that try to coerce arguments to the expected type
+ *   (which is also the case with other *date-fns* functions).
+ *
+ * @param {*} date - the date to check

+ *
+ * @description
+ * Is the given date within the interval? (Including start and end.)
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The function was renamed from `isWithinRange` to `isWithinInterval`.
+ *   This change was made to mirror the use of the word "interval" in standard ISO 8601:2004 terminology:
+ *
+ *   ```
+ *   2.1.3
+ *   time interval
+ *   part of the time axis limited by two instants
+ *   ```
+ *
+ *   Also, this function now accepts an object with `start` and `end` properties
+ *   instead of two arguments as an interval.
+ *   This function now throws `RangeError` if the start of the interval is after its end
+ *   or if any date in the interval is `Invalid Date`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *
+ *   isWithinRange(
+ *     new Date(2014, 0, 3),
+ *     new Date(2014, 0, 1), new Date(2014, 0, 7)
+ *   )
+ *
+ *   // v2.0.0 onward
+ *
+ *   isWithinInterval(
+ *     new Date(2014, 0, 3),
+ *     { start: new Date(2014, 0, 1), end: new Date(2014, 0, 7) }
+ *   )
+ *   ```
+ *
+ * @param {Date|Number} date - the date to check
+ * @param {Interval} interval - the interval to check
+ * @returns {Boolean} the date is within the interval
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} The start of an interval cannot be after its end
+ * @throws {RangeError} Date in interval cannot be `Invalid Date`
+ *
+ * @example
+ * // For the date within the interval:
+ * isWithinInterval(new Date(2014, 0, 3), {
+ *   start: new Date(2014, 0, 1),
+ *   end: new Date(2014, 0, 7)
+ * })
+ * //=> true
+ *
+ * @example
+ * // For the date outside of the interval:
+ * isWithinInterval(new Date(2014, 0, 10), {
+ *   start: new Date(2014, 0, 1),
+ *   end: new Date(2014, 0, 7)
+ * })
+ * //=> false
+ *
+ * @example
+ * // For date equal to interval start:
+ * isWithinInterval(date, { start, end: date }) // => true
+ *
+ * @example
+ * // For date equal to interval end:
+ * isWithinInterval(date, { start: date, end }) // => true

+ *
+ * - `max` function now accepts an array of dates rather than spread arguments.

+ *   // Before v2.0.0
+ *   var date1 = new Date(1989, 6, 10)
+ *   var date2 = new Date(1987, 1, 11)
+ *   var maxDate = max(date1, date2)
+ *
+ *   // v2.0.0 onward:
+ *   var dates = [new Date(1989, 6, 10), new Date(1987, 1, 11)]
+ *   var maxDate = max(dates)
+ *   ```
+ *
+ * @param {Date[]|Number[]} datesArray - the dates to compare
+ * @returns {Date} the latest of the dates
+ * @throws {TypeError} 1 argument required
+ *
+ * @example
+ * // Which of these dates is the latest?
+ * var result = max([
+ *   new Date(1989, 6, 10),
+ *   new Date(1987, 1, 11),

+/**
+ * @name parse
+ * @category Common Helpers
+ * @summary Parse the date.
+ *
+ * @description
+ * Return the date parsed from string using the given format string.
+ *
+ * > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
+ * > See: https://git.io/fxCyr
+ *
+ * The characters in the format string wrapped between two single quotes characters (') are escaped.
+ * Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
+ *
+ * Format of the format string is based on Unicode Technical Standard #35:
+ * https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
+ * with a few additions (see note 5 below the table).
+ *
+ * Not all tokens are compatible. Combinations that don't make sense or could lead to bugs are prohibited
+ * and will throw `RangeError`. For example usage of 24-hour format token with AM/PM token will throw an exception:
+ *
+ * ```javascript
+ * parse('23 AM', 'HH a', new Date())
+ * //=> RangeError: The format string mustn't contain `HH` and `a` at the same time
+ * ```
+ *
+ * See the compatibility table: https://docs.google.com/spreadsheets/d/e/2PACX-1vQOPU3xUhplll6dyoMmVUXHKl_8CRDs6_ueLmex3SoqwhuolkuN3O05l4rqx5h1dKX8eb46Ul-CCSrq/pubhtml?gid=0&single=true

+ *    In `format` function, they will produce different result:
+ *
+ *    `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`
+ *
+ *    `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`
+ *
+ *    `parse` will try to match both formatting and stand-alone units interchangably.
+ *
+ * 2. Any sequence of the identical letters is a pattern, unless it is escaped by
+ *    the single quote characters (see below).
+ *    If the sequence is longer than listed in table:
+ *    - for numerical units (`yyyyyyyy`) `parse` will try to match a number
+ *      as wide as the sequence
+ *    - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit.
+ *      These variations are marked with "2" in the last column of the table.
+ *
+ * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.
+ *    These tokens represent the shortest form of the quarter.
+ *
+ * 4. The main difference between `y` and `u` patterns are B.C. years:
+ *
+ *    | Year | `y` | `u` |
+ *    |------|-----|-----|
+ *    | AC 1 |   1 |   1 |
+ *    | BC 1 |   1 |   0 |
+ *    | BC 2 |   2 |  -1 |
+ *
+ *    Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`:
+ *
+ *    `parse('50', 'yy', new Date(2018, 0, 1)) //=> Sat Jan 01 2050 00:00:00`
+ *
+ *    `parse('75', 'yy', new Date(2018, 0, 1)) //=> Wed Jan 01 1975 00:00:00`
+ *
+ *    while `uu` will just assign the year as is:
+ *
+ *    `parse('50', 'uu', new Date(2018, 0, 1)) //=> Sat Jan 01 0050 00:00:00`
+ *
+ *    `parse('75', 'uu', new Date(2018, 0, 1)) //=> Tue Jan 01 0075 00:00:00`
+ *
+ *    The same difference is true for local and ISO week-numbering years (`Y` and `R`),
+ *    except local week-numbering years are dependent on `options.weekStartsOn`
+ *    and `options.firstWeekContainsDate` (compare [setISOWeekYear]{@link https://date-fns.org/docs/setISOWeekYear}
+ *    and [setWeekYear]{@link https://date-fns.org/docs/setWeekYear}).
+ *
+ * 5. These patterns are not in the Unicode Technical Standard #35:
+ *    - `i`: ISO day of week
+ *    - `I`: ISO week of year
+ *    - `R`: ISO week-numbering year
+ *    - `o`: ordinal number modifier
+ *    - `P`: long localized date
+ *    - `p`: long localized time
+ *
+ * 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.
+ *    You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://git.io/fxCyr
+ *
+ * 7. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.
+ *    You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://git.io/fxCyr
+ *
+ * 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based
+ *    on the given locale.
+ *
+ *    using `en-US` locale: `P` => `MM/dd/yyyy`
+ *    using `en-US` locale: `p` => `hh:mm a`
+ *    using `pt-BR` locale: `P` => `dd/MM/yyyy`
+ *    using `pt-BR` locale: `p` => `HH:mm`
+ *
+ * Values will be assigned to the date in the descending order of its unit's priority.
+ * Units of an equal priority overwrite each other in the order of appearance.
+ *
+ * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),
+ * the values will be taken from 3rd argument `referenceDate` which works as a context of parsing.
+ *
+ * `referenceDate` must be passed for correct work of the function.
+ * If you're not sure which `referenceDate` to supply, create a new instance of Date:
+ * `parse('02/11/2014', 'MM/dd/yyyy', new Date())`
+ * In this case parsing will be done in the context of the current date.
+ * If `referenceDate` is `Invalid Date` or a value not convertible to valid `Date`,
+ * then `Invalid Date` will be returned.
+ *
+ * The result may vary by locale.
+ *
+ * If `formatString` matches with `dateString` but does not provides tokens, `referenceDate` will be returned.
+ *
+ * If parsing failed, `Invalid Date` will be returned.
+ * Invalid Date is a Date, whose time value is NaN.
+ * Time value of Date: http://es5.github.io/#x15.9.1.1
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - Old `parse` was renamed to `toDate`.
+ *   Now `parse` is a new function which parses a string using a provided format.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *   parse('2016-01-01')
+ *
+ *   // v2.0.0 onward (toDate no longer accepts a string)
+ *   toDate(1392098430000) // Unix to timestamp
+ *   toDate(new Date(2014, 1, 11, 11, 30, 30)) // Cloning the date
+ *   parse('2016-01-01', 'yyyy-MM-dd', new Date())
+ *   ```
+ *
+ * @param {String} dateString - the string to parse
+ * @param {String} formatString - the string of tokens
+ * @param {Date|Number} referenceDate - defines values missing from the parsed dateString
+ * @param {Object} [options] - an object with options.
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
+ * @param {1|2|3|4|5|6|7} [options.firstWeekContainsDate=1] - the day of January, which is always in the first week of the year
+ * @param {Boolean} [options.useAdditionalWeekYearTokens=false] - if true, allows usage of the week-numbering year tokens `YY` and `YYYY`;
+ *   see: https://git.io/fxCyr
+ * @param {Boolean} [options.useAdditionalDayOfYearTokens=false] - if true, allows usage of the day of year tokens `D` and `DD`;
+ *   see: https://git.io/fxCyr
+ * @returns {Date} the parsed date
+ * @throws {TypeError} 3 arguments required
+ * @throws {RangeError} `options.weekStartsOn` must be between 0 and 6
+ * @throws {RangeError} `options.firstWeekContainsDate` must be between 1 and 7
+ * @throws {RangeError} `options.locale` must contain `match` property
+ * @throws {RangeError} use `yyyy` instead of `YYYY` for formatting years using [format provided] to the input [input provided]; see: https://git.io/fxCyr
+ * @throws {RangeError} use `yy` instead of `YY` for formatting years using [format provided] to the input [input provided]; see: https://git.io/fxCyr
+ * @throws {RangeError} use `d` instead of `D` for formatting days of the month using [format provided] to the input [input provided]; see: https://git.io/fxCyr
+ * @throws {RangeError} use `dd` instead of `DD` for formatting days of the month using [format provided] to the input [input provided]; see: https://git.io/fxCyr
+ * @throws {RangeError} format string contains an unescaped latin alphabet character
+ *
+ * @example
+ * // Parse 11 February 2014 from middle-endian format:
+ * var result = parse('02/11/2014', 'MM/dd/yyyy', new Date())
+ * //=> Tue Feb 11 2014 00:00:00
+ *
+ * @example

+ * import eo from 'date-fns/locale/eo'
+ * var result = parse('28-a de februaro', "do 'de' MMMM", new Date(2010, 0, 1), {

+ * @name parseISO
+ * @category Common Helpers
+ * @summary Parse ISO string
+ *
+ * @description
+ * Parse the given string in ISO 8601 format and return an instance of Date.
+ *
+ * Function accepts complete ISO 8601 formats as well as partial implementations.
+ * ISO 8601: http://en.wikipedia.org/wiki/ISO_8601
+ *
+ * If the argument isn't a string, the function cannot parse the string or
+ * the values are invalid, it returns Invalid Date.
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * - The previous `parse` implementation was renamed to `parseISO`.
+ *
+ *   ```javascript
+ *   // Before v2.0.0
+ *   parse('2016-01-01')
+ *
+ *   // v2.0.0 onward
+ *   parseISO('2016-01-01')
+ *   ```
+ *
+ * - `parseISO` now validates separate date and time values in ISO-8601 strings
+ *   and returns `Invalid Date` if the date is invalid.
+ *
+ *   ```javascript
+ *   parseISO('2018-13-32')
+ *   //=> Invalid Date
+ *   ```
+ *
+ * - `parseISO` now doesn't fall back to `new Date` constructor
+ *   if it fails to parse a string argument. Instead, it returns `Invalid Date`.
+ *
+ * @param {String} argument - the value to convert
+ * @param {Object} [options] - an object with options.
+ * @param {0|1|2} [options.additionalDigits=2] - the additional number of digits in the extended year format
+ * @returns {Date} the parsed date in the local time zone
+ * @throws {TypeError} 1 argument required
+ * @throws {RangeError} `options.additionalDigits` must be 0, 1 or 2
+ *
+ * @example
+ * // Convert string '2014-02-11T11:30:30' to date:
+ * var result = parseISO('2014-02-11T11:30:30')
+ * //=> Tue Feb 11 2014 11:30:30
+ *
+ * @example
+ * // Convert string '+02014101' to date,
+ * // if the additional number of digits in the extended year format is 1:
+ * var result = parseISO('+02014101', { additionalDigits: 1 })
+ * //=> Fri Apr 11 2014 00:00:00

+/**
+ * @name parseJSON
+ * @category Common Helpers
+ * @summary Parse a JSON date string
+ *
+ * @description
+ * Converts a complete ISO date string in UTC time, the typical format for transmitting
+ * a date in JSON, to a JavaScript `Date` instance.
+ *
+ * This is a minimal implementation for converting dates retrieved from a JSON API to
+ * a `Date` instance which can be used with other functions in the `date-fns` library.
+ * The following formats are supported:
+ *
+ * - `2000-03-15T05:20:10.123Z`: The output of `.toISOString()` and `JSON.stringify(new Date())`
+ * - `2000-03-15T05:20:10Z`: Without milliseconds
+ * - `2000-03-15T05:20:10+00:00`: With a zero offset, the default JSON encoded format in some other languages
+ * - `2000-03-15T05:20:10+05:45`: With a positive or negative offset, the default JSON encoded format in some other languages
+ * - `2000-03-15T05:20:10+0000`: With a zero offset without a colon
+ * - `2000-03-15T05:20:10`: Without a trailing 'Z' symbol
+ * - `2000-03-15T05:20:10.1234567`: Up to 7 digits in milliseconds field. Only first 3 are taken into account since JS does not allow fractional milliseconds
+ * - `2000-03-15 05:20:10`: With a space instead of a 'T' separator for APIs returning a SQL date without reformatting
+ *
+ * For convenience and ease of use these other input types are also supported
+ * via [toDate]{@link https://date-fns.org/docs/toDate}:
+ *
+ * - A `Date` instance will be cloned
+ * - A `number` will be treated as a timestamp
+ *
+ * Any other input type or invalid date strings will return an `Invalid Date`.
+ *
+ * @param {String|Number|Date} argument A fully formed ISO8601 date string to convert
+ * @returns {Date} the parsed date in the local time zone
+ * @throws {TypeError} 1 argument required

+ * @description
+ * Set date values to a given date.
+ *
+ * Sets time values to date from object `values`.
+ * A value is not set if it is undefined or null or doesn't exist in `values`.
+ *
+ * Note about bundle size: `set` does not internally use `setX` functions from date-fns but instead opts
+ * to use native `Date#setX` methods. If you use this function, you may not want to include the
+ * other `setX` functions that date-fns provides if you are concerned about the bundle size.
+ *
+ * @param {Date|Number} date - the date to be changed
+ * @param {Object} values - an object with options
+ * @param {Number} [values.year] - the number of years to be set
+ * @param {Number} [values.month] - the number of months to be set
+ * @param {Number} [values.date] - the number of days to be set
+ * @param {Number} [values.hours] - the number of hours to be set
+ * @param {Number} [values.minutes] - the number of minutes to be set
+ * @param {Number} [values.seconds] - the number of seconds to be set
+ * @param {Number} [values.milliseconds] - the number of milliseconds to be set
+ * @returns {Date} the new date with options set
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} `values` must be an object
+ *
+ * @example
+ * // Transform 1 September 2014 into 20 October 2015 in a single line:
+ * var result = set(new Date(2014, 8, 20), { year: 2015, month: 9, date: 20 })
+ * //=> Tue Oct 20 2015 00:00:00

+ * @example
+ * // Set 12 PM to 1 September 2014 01:23:45 to 1 September 2014 12:00:00:
+ * var result = set(new Date(2014, 8, 1, 1, 23, 45), { hours: 12 })

+ * @name setWeekYear
+ * @category Week-Numbering Year Helpers
+ * @summary Set the local week-numbering year to the given date.
+ *
+ * @description
+ * Set the local week-numbering year to the given date,
+ * saving the week number and the weekday number.
+ * The exact calculation depends on the values of
+ * `options.weekStartsOn` (which is the index of the first day of the week)
+ * and `options.firstWeekContainsDate` (which is the day of January, which is always in
+ * the first week of the week-numbering year)
+ *
+ * Week numbering: https://en.wikipedia.org/wiki/Week#Week_numbering
+ *
+ * ### v2.0.0 breaking changes:
+ *
+ * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
+ *
+ * @param {Date|Number} date - the date to be changed
+ * @param {Number} weekYear - the local week-numbering year of the new date
+ * @param {Object} [options] - an object with options.
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
+ * @param {1|2|3|4|5|6|7} [options.firstWeekContainsDate=1] - the day of January, which is always in the first week of the year
+ * @returns {Date} the new date with the local week-numbering year set
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} `options.weekStartsOn` must be between 0 and 6
+ * @throws {RangeError} `options.firstWeekContainsDate` must be between 1 and 7
+ *
+ * @example
+ * // Set the local week-numbering year 2004 to 2 January 2010 with default options:
+ * var result = setWeekYear(new Date(2010, 0, 2), 2004)
+ * //=> Sat Jan 03 2004 00:00:00
+ *
+ * @example
+ * // Set the local week-numbering year 2004 to 2 January 2010,
+ * // if Monday is the first day of week
+ * // and 4 January is always in the first week of the year:
+ * var result = setWeekYear(new Date(2010, 0, 2), 2004, {
