Eid-ul-Adha, Eid-ul-Zuha or Bakrid is celebrated on the tenth day of Dhul-hijja, the twelfth month in the Muslim calendar. The Id-ul-Azha commemorates the ordeal of Prophet Ibrahim, who was commanded at his ripe old age by Allah to sacrifice his only son Ismail, who was dearest to him. Prophet Ibrahim decided to sacrifice the life of his son Ismail in deference to the wishes of Allah. He called Ismail and mentioned to him about his decision. Ismail dutifully agreed to be sacrificed to please Allah. Prophet Ibrahim then blindfolded Ismail and cut off his son's head, only to discover on opening his eyes, that his son was alive and a ram had been sacrificed instead. Since then, a ram or bakra is sacrificed in the name of Allah.

Eid ul-Adha is three days long and starts on the 10th day of the month of Dhul Hijja of the lunar Islamic calendar. This 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.
