The UmAlQuraCalendar class is nearly identical to the HijriCalendar class, except the Saudi Hijri calendar uses a table-based algorithm licensed from the Saudi government to calculate dates, can express dates to the year 1450 A.H., and does not support the HijriAdjustment property.

For the UmAlQuraCalendar class, each month has either 29 or 30 days, but usually in no discernible order. Whereas the documentation for the Hijri Calendar gives a table that shows the corresponding days in each month, no such general table can be produced for the Um Al Qura calendar.

For more information about the Hijri calendar, see the HijriCalendar class.

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).
