The next upcoming Eid al Adha starts on sundown of August 10 ending at sundown on Monday August 11th, 2019. Eid al-Adha is held around the 10th to the 13th days of the Islamic month of Dhu al-Hijjah and commemorates Ibrahim's sacrifice of his son to God.
People are supposed to dress in their finest clothing to pray in a large open area or Mosque. Family and friends get together for a large lunch or late breakfast. Animals may be sacrificed as a symbolic reference to Abraham's willingness to sacrifice his only son. The meat is often divided into three with one third going to the relatives, another third going to the poor and the last third eaten directly by themselves to celebrate. Many people give to charities to support those who have less on this day.
The day is often referred to as Feast of the Sacrifice, which honors the willingness of Ibrahim to sacrifice his son Ismail showing submission to God. Eid al-Adha marks the end of the annual Hajj to Mecca.
