Known as Eid al-Adha, Eid ul Adha, Id-ul-Azha, Id-ul-Zuha, Hari Raya Haji or Bakr-id; the 'Feast of Sacrifice' is the most important feast of the Muslim calendar.

The festival may also be known as Al Eid Al Kabeer, which means the 'Grand Eid'. It has this more important status as in religious terms as this Eid lasts for four days whereas Eid Al Fitr is one day, even though most countries observe about the same number of public holidays for both Eids.

This festival is celebrated throughout the Muslim world as a commemoration of Prophet Abraham's willingness to sacrifice everything for God.

Eid al-Adha falls on the 10th day of Dhu al-Hijjah, the twelfth and final month in the Islamic calendar.

As the exact day is based on lunar sightings, the date may vary between countries.
