Common mistakes

  • Confusing Eid al-Adha with Eid al-Fitr. They are two distinct holidays roughly two and a half months apart — Eid al-Fitr ends Ramadan, while Eid al-Adha falls during the Hajj season.
  • Treating the estimate as officially confirmed. National and local authorities typically announce the confirmed date only shortly beforehand, based on moon sighting.
  • Assuming it lands on the same Gregorian date each year. Like all Hijri dates, it shifts about 10-11 days earlier in the Gregorian calendar annually.
