When is Eid al-Adha 2021?
EID al-Adha is one of the key festivals in the Muslim calendar. The event is a celebration of Ibrahim agreeing to sacrifice his son Ishmael under God's command. Eid al-Adha is celebrated on the 10th day of Dh al-Hijjah, the twelfth and final month of the Islamic calendar. In 2021, the four-day event will begin on the evening of July 19 and end on July 23. Eid al-Adha usually starts with Muslims going to the Mosque for prayers in new finery. As it is known as the 'Festival of Sacrifice', a sheep, goat, camel or cow is usually sacrificed during the period. This is called Qurbani. In many countries this is done as part of a public ritual, but in the UK it takes place in a slaughterhouse. The meat is shared equally between family, friends and the poor, along with a big feast of mostly savoury dishes. Relatives will gather for the celebrations and exchange gifts, cards and money, as well as donating to charity. Some Muslims will also travel to Mecca and the surrounding area in Saudi Arabia to perform the Hajj pilgrimage, which is one of the five pillars of Islam. Overall, this year's celebrations may look slightly different due to the coronavirus pandemic restrictions in place across the globe. 3 A breeder poses for a photo near sacrificial lambs at a livestock market Credit: Getty  Eid means "celebration" and Mubarak means "blessed" and "Eid Mubarak" is often used as a greeting over this period. The saying can be translated as "have a blessed holiday", or "blessed feast/festival". It is customary to reply "Khair Mubarak" which reciprocates the good wishes. Eid al-Adha is the second major Muslim festival after Eid al-Fitr. While Eid al-Adha is known as the 'Festival of Sacrifice', Eid al-Fitr is also called the 'Festival of Breaking the Fast'. It is celebrated at the end of Ramadan to mark the end of fasting.

Eid al-Adha tends to be predominantly savoury and is the holier of the two feasts. It coincides with the end of the Hajj pilgrimage to Mecca, Saudi Arabia, and is around two months after Eid al-Fitr. 3 A Muslim offers prayers during the feast of sacrifice at the Badshahi mosque in Lahore, Pakistan Credit: AFP
