The festival of Eid al-Fitr, the Festival of Fast-breaking, is an important religious holiday celebrated by Muslims worldwide that marks the end of Ramadan, the Islamic holy month of fasting.  The holiday celebrates the conclusion of the 29 or 30 days of dawn-to-sunset fasting during the entire month of Ramadan. 

As the date of Eid depends on the sighting of the moon, there may be variations in the exact date that is celebrated around the world. The announcement of the exact dates of Eid Al-Fitr may not happen until close to the start of Ramadan
