Although Ramadan 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 Ramadan moves in the Gregorian calendar approximately 11 days every year. The date of Ramadan 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 Ramadan. 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.
The Astronomical New Moon is on July 5, 2016 (Wednesday) at 1:24 Universal Time. (4:23 a.m. on July 6, Makkah time). On July 6, Thursday, sunset at Makkah is 7:05 p.m. and moonset is at 7:17 p.m. Moon is born before sunset, and moon sets after sunset. Therefore, first day of Shawwal, i.e., Eid ul-Fitr is July 7, Friday, insha’Allah.
