How to calculate

Counts the days from today, or any date you choose, to the next Eid al-Adha, with its date and day of the week.

Example with the default inputs (Count from September 30, 2026) on the example date Wednesday, September 30, 2026: From September 30, 2026, there are 228 days until Eid al-Adha on Sunday, May 16, 2027.

Method: Find the first date of Eid al-Adha on or after the start date, then count the days from the start date to it.

  • Eid al-Adha is on 10 Dhu al-Hijjah, the day after the Day of Arafah during the Hajj (here on the Umm al-Qura calendar).
  • Where the month starts when the new crescent is seen, the day observed can be a day later, or rarely earlier.
  • Start dates from January 1, 2000 to December 31, 2076 work, because the published Umm al-Qura table used here runs from 1420 AH (1999) to 1500 AH (2077).
  • The start date itself is not counted: from the day before, the count is 1; on the day itself, it is 0.
  • Dates are calendar days with no time of day, so a time zone or a daylight-saving change never adds or loses a day.

Why can Eid al-Adha be on a different day where I live?

The dates here follow the Umm al-Qura calendar, the civil calendar of Saudi Arabia, which is computed from the Moon’s position in advance. Many communities, and the religious authorities in Saudi Arabia too, start the month when the new crescent is seen, so the day observed where you live can be a day later, or rarely a day earlier. Check with your local mosque or Islamic center.
