first of two canonical festivals of Islam. Eid al-Fitr marks the end of Ramadan, the Muslim holy month of fasting, and is celebrated during the first three days of Shawwāl, the 10th month of the Islamic calendar (though the Muslim use of a lunar calendar means that it may fall in any season of the year). As in Islam’s other holy festival, Eid al-Adha, it is distinguished by the performance of communal prayer (ṣalāt) at daybreak on its first day.
