“Eid ul-Fitr, Eid al-Fitr, Id-ul-Fitr, or Id al-Fitr, often abbreviated to Eid, is a Muslim holiday that marks the end of Ramadan, the Islamic holy month of fasting (sawm). Eid is an Arabic word meaning “festivity”, while Fiṭr means “breaking (the fast)”. The holiday celebrates the conclusion of the twenty nine or thirty days of dawn-to-sunset fasting during the entire month of Ramadan. The first day of Eid, therefore, falls on the first day of the month Shawwal”. – Wikipedia
