Moulid (Mawlid al-Nabi)
Moulid (also spelled Mawlid al-Nabi, Mawlid an-Nabi or Milad al-Nabi) celebrates the birthday of the Prophet Mohammed. Note that in the Muslim calender, a holiday begins on the sunset of the previous day, so observing Muslims will begin celebrating Mawlid al-Nabi on the sunset of October 18, 2021.
Although Mawlid al-Nabi 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 Mawlid al-Nabi moves in the Gregorian calendar approximately 11 days every year. The date of Mawlid al-Nabi 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 Mawlid al-Nabi.
