+ * @name subDays
+ * @category Day Helpers
+ * @summary Subtract the specified number of days from the given date.
+ *
+ * @description
+ * Subtract the specified number of days from the given 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).
+ *
+ * @param {Date|Number} date - the date to be changed
+ * @param {Number} amount - the amount of days to be subtracted. Positive decimals will be rounded using `Math.floor`, decimals less than zero will be rounded using `Math.ceil`.
+ * @returns {Date} the new date with the days subtracted
+ * @throws {TypeError} 2 arguments required
+ *
+ * @example
+ * // Subtract 10 days from 1 September 2014:
+ * const result = subDays(new Date(2014, 8, 1), 10)
+ * //=> Fri Aug 22 2014 00:00:00
