Happy New Year 1427

Al-Hijra, the Islamic New Year, is the first day of the month of Muharram. It marks the Hijra (or Hegira) in 622 CE when the Prophet Muhammad (pbuh) moved from Mecca to Medina, and set up the first Islamic state.
The Muslim calendar counts dates from the Hijra, which is why Muslim dates have the suffix A.H. (After Hijra).
