Eid al-Fitr, also called Feast of Breaking the Fast, the Sugar Feast, the Sweet Festival and the Lesser Eid, is an important religious holiday celebrated by Muslims worldwide that marks the end of Ramadan, the Islamic holy month of fasting (sawm). The religious Eid is a single day and Muslims are not permitted to fast that day. The holiday celebrates the conclusion of the 29 or 30 days of dawn-to-sunset fasting during the entire month of Ramadan. The day of Eid, therefore, falls on the first day of the month of Shawwal. This is a day where Muslims around the world try to show a common goal of unity. Since some of the countries have different calculation and observation techniques, the day of celebration may change 1 day depending on the country, but in most of the Islamic countries, it is celebrated on the same day.

Eid al-Fitr has a particular salat (Islamic prayer) consisting of two rakats (units) and generally offered in an open field or large hall. It may only be performed in congregation (Jama’at) and has an additional extra six Takbirs (raising of the hands to the ears while saying "Allahu Akbar" [God is Great]), three of them in the beginning of the first raka'ah and three of them just before ruku' in the second raka'ah in the Hanafi school. This Eid al-Fitr salat is, depending on which juristic opinion is followed, Fard (obligatory), Mustahabb (strongly recommended, just short of obligatory) or mandoob (preferable).

Muslims believe that they are commanded by God, as mentioned in the Quran, to continue their fast until the last day of Ramadan and pay the Zakat and fitra before offering the Eid prayers.
