The Hijri calendar recognizes one era: A.H. (Latin "Anno Hegirae", which means "the year of the migration," in reference to the migration of Muhammad (PBUH) from Mecca).
In every 30-year cycle that ends with a year that is evenly divisible by 30, the 2nd, 5th, 7th, 10th, 13th, 16th, 18th, 21st, 24th, 26th, and 29th years are leap years. A common year has 354 days and a leap year has 355 days.
The Hijri calendar has 12 months with 29 to 30 days each:
|GetMonth value||Month||Days in common years||Days in leap years|
|3||ربيع الاول (Rabi I)||30||30|
|4||ربيع الثاني (Rabi II)||29||29|
|5||جمادى الاولى (Jumada I)||30||30|
|6||جمادى الثانية (Jumada II)||29||29|
|11||ذو القعدة (Zulkadah)||30||30|
|12||ذو الحجة (Zulhijjah)||29||30|
Ramadan, the month of fasting in the Muslim world, officially starts and ends according to a decree that is based on the observation of the new moon. Therefore, the number of days in Shaban and the number of days in Ramadan vary.
The date January 1, 2001 A.D. in the Gregorian calendar is roughly equivalent to the sixth day of Shawwal in the year 1421 A.H. in the Hijri calendar.
This implementation of the HijriCalendar class adjusts the calendar date by adding or subtracting a value from zero to two days to accommodate the variances in the start and the end of Ramadan and to accommodate the date difference between countries/regions. That value is stored in the HijriAdjustment property. If HijriAdjustment is not set explicitly, it derives its value from the settings in the regional and language options portion of Control Panel and is stored in the registry value HKEY_CURRENT_USER\Control Panel\International\AddHijriDate. However, that information can change during the life of the AppDomain. The HijriCalendar class does not detect changes in the system settings automatically.
Each CultureInfo supports a set of calendars. The Calendar property returns the default calendar for the culture, and the OptionalCalendars property returns an array containing all the calendars supported by the culture. To change the calendar used by a CultureInfo, the application should set the Calendar property of CultureInfo.DateTimeFormat to a new Calendar.
