Eid al-Adha traditionally extends across four days, from 10 to 13 Dhu al-Hijjah.
The festival begins on 10 Dhu al-Hijjah, the day associated with the Hajj pilgrimage’s major rites and the sacrifice tradition commemorating Ibrahim’s willingness to obey God. The following three days are called the Days of Tashreeq, giving the observance a four-day span in the Islamic calendar.
Eid al-Adha is also known as the Festival of Sacrifice. Muslims who are able may perform an animal sacrifice, and the meat is commonly divided among household members, relatives or neighbors, and people in need. Practices and legal details vary by community and country.
The four-day period is distinct from the one-day principal festival date often printed on calendars. Gregorian dates shift annually because Dhu al-Hijjah belongs to the lunar Islamic calendar, which is shorter than the solar year.
