Idul-Fitr, of late known by the misnomer 'Ramadan' is one of the two festivals of Islam. Ramadan is the ninth month of the lunar year.
Although Eid ul Fitr is always on the same day of the Islamic calendar, the date on the Gregorian calendar varies every year, because the Gregorian calendar is a solar calendar and the Islamic calendar is a lunar calendar. This difference means Eid ul Fitr moves in the Gregorian calendar approximately eleven days every year. The date of Eid ul Fitr may also vary from country to country depending on whether the moon has been sighted or not.
Idul Fitr in Kereala is celebrated after the conclusion of the Ramzan. During Kerala Idul Fitr, the Muslims observe fast, giving up all kinds of food and drink during day time, and spend the major part of the night in devotion and prayer. Purification of the body and soul is the main aim of this observance.
When the crescent appears on the western horizon heralding the end of the month of fasting, it marks the beginning of the Idul-Fitr festival. Because this festival is connected with the month of Ramadan, it came to be known as 'Ramadan'.
The Kerala Id Ul Fitr festival starts with the commencement of the first day of the month of 'Shawwal'.
