Eid al-Adha is a religious festival celebrated by Muslims and Druze worldwide as a commemoration of Ibrahim's (Abraham's) willingness to sacrifice his son Ismael for Allah. It is one of two Eid festivals that Muslims celebrate (Muslims in Iran celebrate a third, non-denominational eid ). Like Eid el-Fitr, Eid ul-Adha begins with a short prayer followed by a sermon (khu?ba). It is also called the bigger Eid because it is considered better than Eid el-Fitr[citation needed]. Eid al-Adha is the 10th day of the month of Dhul Hijja (of the lunar Islamic calendar. The festivities sometimes last for two to three days more depending on the country. It is the day after the pilgrims in Hajj, the annual pilgrimage to Mecca in Saudi Arabia by Muslims worldwide, descend from Mount Arafat. It happens to be approximately 70 days after the end of the month of Ramadan.
