The UmAlQuraCalendar class is nearly identical to the HijriCalendar class, except that the UmAlQuraCalendar class:
Uses a table-based algorithm licensed from the Saudi government to calculate dates.
Consists of months that have either 29 or 30 days, although the precise number of days in a month is usually not predictable. Although the documentation for the HijriCalendar class includes a table that shows the corresponding days in each month, no such general table can be produced for the UmAlQuraCalendar class.
Can express dates to the year 1450 A.H. (Latin "Anno Hegirae", which means "the year of the migration," in reference to the migration of Muhammad from Mecca).
Does not support the HijriCalendar::HijriAdjustment property.
Each CultureInfo object supports a set of calendars. The CultureInfo::Calendar property returns the default calendar for the culture, and the CultureInfo::OptionalCalendars property returns an array that contains all the calendars supported by the culture. To change the calendar used by a CultureInfo object, the application can set the Calendar property of CultureInfo::DateTimeFormat to a new Calendar object if the new calendar is one of the culture's optional calendars. The following example shows how to change the calendar for the ar-AE culture to the Um Al Qura calendar.
Note The UmAlQuraCalendar class supports only dates from 04/30/1900 00.00.00 (Gregorian date) through 05/13/2029 23:59:59 (Gregorian date). An ArgumentOutOfRangeException is thrown if the calendar attempts to handle any date outside that range.
