Muslims celebrate ‘Eid ul Fitr on the first day of Shawwal — the tenth month of the Islamic calendar, following the month of Ramadhan (in which the revelation started and ended 20+ years later, and which is also the month of fasting). Following a Lunar calendar, Muslims mark the beginning of the month with the sighting of the new crescent.
The month long fasting of Ramadaan culminates into the festival of ‘Eid-ul-Fitr (the Festival of Fast-Breaking). It is a festival of joy, family reunion and thanksgiving to Almighty God. The giving of a special charity for this occasion is obligatory. This is known as Zakat. Muslims dress in holiday attire, attend a special community prayer in the morning, and visit friends and relatives. Greetings of “‘Eid mubarak,” or “a blessed ‘Eid” are exchanged.
