From Wikipedia: Eid al-Fitr (/iːd əl ˈfɪtər/ eed əl FIT-ər; Arabic: عيد الفطر ʻĪd al-Fiṭr, IPA: [ʕiːd al fitˤr]),[3] also called the "Festival of Breaking the Fast" or Lesser Eid, or simply Eid,[4] is a religious holiday celebrated by Muslims worldwide that marks the end of the month-long dawn-to-sunset fasting of Ramadan.[5] The date for the start of any lunar Hijri month varies based on when the new moon is sighted by local religious authorities, so the day of celebration varies by locality. The holiday is known under various other names in different languages and countries around the world.
