Taking place two months or so after Eid al-Fitr, this celebration is the feast of the sacrifice. It remembers a story about Allah asking Abraham to sacrifice his son, as a sign of faith. Its also the time of year when many Muslims make a five-day pilgrimage to the city of Mecca in Saudi Arabia, called Hajj. All Muslims who are able to make the pilgrimage are expected to travel to Mecca once in their lifetime  to pray before Kaaba, the religions most sacred shrine.

Though it is an important time in the calendar, the actual date Eid al-Adha happens varies year on year, much like Easter. This is because it is based on the lunar calendar and the sighting of a new moon. The sighting of the new moon varies across the world, so the exact date can change depending on where you and on local religious authorities. For example, in Pakistan, India, Bangladesh the current expected date for Eid al-Adha is July 21, but these dates are also subject to change. In 2020, it took place from July 30 to August 3, and in 2019 from August 11 to August 15. In 2022, Eid al-Adha is due to take place from Saturday, July 9 to Wednesday, July 13.
