Which Islamic festival begins on 10 Dhu al-Hijjah, after the Day of Arafah?

Eid al-Adha begins on 10 Dhu al-Hijjah, after the Day of Arafah. It is one of the two major Islamic festivals and occurs during the Hajj season, the annual pilgrimage to Mecca.

The festival is associated with Ibrahim’s willingness to sacrifice his son in obedience to God. Islamic tradition says that God provided an animal instead, and Muslims commemorate this story through prayer, charity, and the sacrifice of permitted livestock where practiced.

Eid al-Adha is distinct from Eid al-Fitr, which follows Ramadan on 1 Shawwal. The date of Eid al-Adha moves through the Gregorian calendar because Dhu al-Hijjah belongs to the Islamic lunar calendar. Local authorities may differ slightly on the exact start date because of moon-sighting practices.
