What is the Hijrah Calendar?
Muslims do not traditionally "celebrate" the beginning of a new year, but we do acknowledge the passing of time, and take time to reflect on our own mortality.

Muslims measure the passage of time using the Islamic (Hijrah) calendar. This calendar has twelve lunar months, the beginnings and endings of which are determined by the sighting of the crescent moon. Years are counted since the Hijrah, which is when the Prophet Muhammad migrated from Mecca to Madinah (approximately July 622 A.D.).

The Islamic calendar was first introduced by the close companion of the Prophet, 'Umar ibn Al-Khattab. During his leadership of the Muslim community, in approximately 638 A.D., he consulted with his advisors in order to come to a decision regarding the various dating systems used at that time.
