Eid al-Fitr (/ˌiːd əl ˈfɪtər, -trə/ EED əl FIT-ər, -⁠rə; Arabic: عيد الفطر‎, romanized: ʿĪd al-Fiṭr, lit. 'Feast of Breaking the Fast', IPA: [ʕiːd al ˈfitˤr]), also called the "Festival of Breaking the Fast" or Lesser Eid, or simply Eid, is a religious holiday celebrated by Muslims worldwide that marks the end of the month-long dawn-to-sunset fasting of Ramadan. It falls on the first day of Shawwal in the Islamic calendar; this does not always fall on the same Gregorian day, as the start of any lunar Hijri month varies based on when the new moon is sighted by local religious authorities. The holiday is known under various other names in different languages and countries around the world.
