Eid ul-Fitr or Ramdan (Ramazaan)

Eid-ul-Fitr, "Eid-ul-fitr", Eid al-Fitr, Id-ul-Fitr, or Id al-Fitr commanly known as Eid, is a Muslim Holiday that marks the end of Ramadan the Islamic holy month of Fasting or Roza. Eid is an Arabic word meaning "festivity", while Fiṭr means "breaking the fast". The holiday celebrates the conclusion of the 29 or 30 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. This is a day where Muslims around the world try to show a common goal of unity. It is a day to recognizance the God.

Eid al-Fitr has a particular Salat (Islamic prayer) consisting of two raka'ah (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 "Allah-u-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 (bligatory), Mustahabb,(strongly recommended, just short of obligatory) or mandoob (preferable).
