  While Eid al-Adha is always on the same day of the Islamic calendar, the date on the Gregorian calendar varies from year to year since the Islamic calendar is a lunar calendar and the Gregorian calendar is a solar calendar. The lunar calendar is approximately eleven days shorter than the solar calendar. Each year, Eid al-Adha (like other Islamic holidays) falls on one of about two to four Gregorian dates in parts of the world, because the boundary of crescent visibility is different from the International Date Line.
  
  The following list shows the official dates of Eid al-Adha for Saudi Arabia as announced by the Supreme Judicial Council. Future dates are estimated according to the Umm al-Qura calendar of Saudi Arabia. The Umm al-Qura calendar is just a guide for planning purposes and not the absolute determinant or fixer of dates. Confirmations of actual dates by moon sighting are applied on the 29th day of the lunar month prior to Dhu al-Hijja to announce the specific dates for both Hajj rituals and the subsequent Eid festival. The three days after the listed date are also part of the festival. The time before the listed date the pilgrims visit Mount Arafat and descend from it after sunrise of the listed day.
  
  In many countries, the start of any lunar Hijri month varies based on the observation of the new moon by local religious authorities, so the exact day of celebration varies by locality.
