=head1 DESCRIPTION

Hijri Calendar begins with the migration from Mecca to Medina of Mohammad (pbuh),
the Prophet of Islam, an event  known  as the Hegira. The initials A.H.  before a
date mean "anno Hegirae" or "after Hegira". The  first  day  of the year is fixed
in the Quran as the first day of the month of Muharram.In 17 AH Umar I,the second
caliph, established the beginning of the era of the Hegira ( 1 Muharram 1 AH ) as
the date that is 16 July 622 CE in the Julian Calendar.

The years are lunar & consist of 12 lunar months. There is no intercalary period,
since the Quran ( Sura IX, verses 36,37 )  sets  the calendar year  at 12 months.
Because the year in the Hijri  calendar is shorter than a solar year, the  months
drift with respect to the seasons, in a cycle 32.50 years.
