It - * is used as the civil calendar in most of the Arab world and the - * liturgical calendar of the Islamic faith worldwide. This calendar - * is also known as the "Hijri" calendar, since it starts at the time - * of Mohammed's emigration (or "hijra") to Medinah on Thursday, - * July 15, 622 AD (Julian). - * <p> - * The Islamic calendar is strictly lunar, and thus an Islamic year of twelve - * lunar months does not correspond to the solar year used by most other - * calendar systems, including the Gregorian. An Islamic year is, on average, - * about 354 days long, so each successive Islamic year starts about 11 days - * earlier in the corresponding Gregorian year. - * <p> - * Each month of the calendar starts when the new moon's crescent is visible - * at sunset. However, in order to keep the time fields in this class - * synchronized with those of the other calendars and with local clock time, - * we treat days and months as beginning at midnight, - * roughly 6 hours after the corresponding sunset. - * <p> - * There are two main variants of the Islamic calendar in existence. The first - * is the <em>civil</em> calendar, which uses a fixed cycle of alternating 29- - * and 30-day months, with a leap day added to the last month of 11 out of - * every 30 years. This calendar is easily calculated and thus predictable in - * advance, so it is used as the civil calendar in a number of Arab countries. - * This is the default behavior of a newly-created <code>IslamicCalendar</code> - * object. - * <p> - * The Islamic <em>religious</em> calendar, however, is based on the <em>observation</em> - * of the crescent moon. It is thus affected by the position at which the - * observations are made, seasonal variations in the time of sunset, the - * eccentricities of the moon's orbit, and even the weather at the observation - * site. This makes it impossible to calculate in advance, and it causes the - * start of a month in the religious calendar to differ from the civil calendar - * by up to three days. - * <p> - * Using astronomical calculations for the position of the sun and moon, the - * moon's illumination, and other factors, it is possible to determine the start - * of a lunar month with a fairly high degree of certainty. However, these - * calculations are extremely complicated and thus slow, so most algorithms, - * including the one used here, are only approximations of the true astronical - * calculations. At present, the approximations used in this class are fairly - * simplistic; they will be improved in later versions of the code. - * <p> - * The {@link #setCivil setCivil} method determines - * which approach is used to determine the start of a month. By default, the - * fixed-cycle civil calendar is used. However, if <code>setCivil(false)</code> - * is called, an approximation of the true lunar calendar will be used. - * - * @see GregorianCalendar - * - * @author Laura Werner - * @author Alan Liu - * @author Steven R.
