The Islamic calendar or Hijri calendar (AH) is a lunar calendar consisting of 12 months in a year of 354 days.

It is used to date events in many Muslim countries (concurrently with the Gregorian calendar), and used by Muslims everywhere to determine the proper days on which to observe the annual fasting, to attend Hajj, and to celebrate other Islamic holidays and occasions.

The first year of this calendar was the Islamic year beginning in AD 622 during which the emigration of prophet Muhammad (PBUH) from Mecca to Medina, known as the Hijra, occurred.
