Pronounced “EED-uhl-FIT-uhr.” A joyous Islamic holiday that marks the end of Ramadan, the month of fasting. It is observed with communal prayers, donations to charity and special meals. Fasting is forbidden on this day. Eid al-Fitr shifts dates every year because Muslims use a lunar calendar that only includes about 354 days. Eid al-Fitr commences with the sighting of the new moon. See Ramadan.
