(Arabic: عيد الفطر ‘Īdu l-Fiṭr), often abbreviated to Eid, is a Muslim holiday that marks the end of Ramadaan, the Islamic holy month of fasting. Eid is an Arabic word meaning "festivity", while Fiṭr means "to break the fast" (and can also mean "nature", from the word "fitrah") and so symbolizes the breaking of the fasting period. (~Wikepedia)
