Ibrahim, known as Abraham in the Christian and Jewish traditions, was commanded by God to sacrifice his adult son. He obeyed and took Ishmael (Ismail or Ismael) to Mount Moriah. Just as he was to sacrifice his son, an angel stopped him and gave him a ram to sacrifice in place of his son. Some people dispute that the son of sacrifice was Isaac (Isḥāq). Regardless, these events are remembered and celebrated at Eid al-Adha.
The Islamic calendar is based on observations of the moon and the length of a particular month can vary between years. For this reason, predicted dates of Eid al-Adha may be corrected at the start of the month of Dhul Hijja. This is around 10 days before the start of the festival.
