NAME

Calendar::Hijri - Interface to Islamic Calendar.

VERSION

Version 0.06

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 and 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.

NOTE: The Hijri date produced by this module can have +1/-1 day error.
