Dhul-Hijjah

Eid al-Adha, the Festival of Sacrifice, commemorates Prophet Abraham's willingness to sacrifice his son in obedience to Allah. Celebrated during Hajj on the 10th of Dhul-Hijjah, Muslims sacrifice animals and distribute meat to family, friends, and the poor.

The Islamic calendar, or Hijri calendar, is a lunar calendar of 12 months beginning with Prophet Muhammad's migration to Medina in 622 CE. It governs Islamic religious observances, festivals, and historical dating throughout the Muslim world.
