Bakr’Eid is the second of two religious holidays celebrated by Muslims worldwide each year. It honors the willingness of Abraham (Ibrahim) to sacrifice his young first-born son Ishmael (Ismail)a as an act of submission to God’s command, before God then intervened to provide Abraham with a lamb to sacrifice instead. In the lunar-based Islamic calendar, Eid al-Adha falls on the 10th day of Dhu al-Hijjah and lasts for four days. In the international Gregorian calendar, the dates vary from year to year, drifting approximately 11 days earlier each year.
