Eid al-Fitr ( عيد الفطر ) in 2009 is on Sunday, the 20th of September.

Muslim holiday begins on the sunset of the previous day, so date in muslim calender is not fixed like Gregorian calendar and muslim will celebrate Eid ul-Fitr on the sunset of Saturday, the 19th of September 2009.

Although Eid al-Fitr is always on the same day of the Islamic calendar, the date on the Gregorian calendar varies from year to year, since the Gregorian calendar is a solar calendar and the Islamic calendar is a lunar calendar. This difference means Eid al-Fitr moves in the Gregorian calendar approximately 11 days every year. The date of Eid al-Fitr may also vary from country to country depending on whether the moon has been sighted or not.

The dates provided here are based on the dates adopted by the Fiqh Council of North America for the celebration of Eid al-Fitr. Note that these dates are based on astronomical calculations to affirm each date, and not on the actual sighting of the moon with the naked eyes. This approach is accepted by many, but is still being hotly debated.
