The "Festival of Sacrifice," commemorating Prophet Ibrahim's willingness to sacrifice his son in obedience to God, observed on 10 Dhu al-Hijjah with prayers and the ritual sacrifice (Qurbani/Udhiyah).

How is Eid al-Adha connected to Hajj?

Eid al-Adha falls during the Hajj pilgrimage period, on the same day pilgrims complete the main rites at Mina, though Muslims worldwide (not just pilgrims) observe the holiday.

Why is Eid al-Adha's date tied to Saudi Arabia's moonsighting specifically?

Because the date is fixed to the Hajj calendar, which is set by Saudi Arabia's own moon sighting for Dhu al-Hijjah — many communities worldwide follow Saudi Arabia's announcement for this holiday even if they use local sighting for other months.

How long does the Eid al-Adha holiday last?

The public holiday itself is often observed over several days in many countries, though the Islamic date of Eid is 10 Dhu al-Hijjah specifically.

Can I look up Eid al-Adha for a past or future year?

Yes — enter any Gregorian year and the tool calculates the tabular date of 10 Dhu al-Hijjah for that year.

What is Dhu al-Hijjah known for besides Eid al-Adha?

It's the month of the Hajj pilgrimage, and — along with Muharram, Rajab, and Dhu al-Qi'dah — one of the four sacred months in Islam.

How accurate is this calculated date compared to the real, announced date?

Typically within a day, since the difference between a tabular calculation and Saudi Arabia's actual moonsighting-based announcement is a well-documented, expected variance.

How to use it

Enter the Gregorian year you want to check.
Read the calculated date of Eid al-Adha (10 Dhu al-Hijjah) shown below.
Note the tabular-calculation disclosure beneath the result — check Saudi Arabia's moonsighting-based Hajj-calendar announcement for the officially observed date.
Try a different year to see how the date shifts about 11 days earlier each Gregorian year.

Formula

Finds the Hijri year whose 10 Dhu al-Hijjah falls within the requested Gregorian year, using the Umm al-Qura tabular calendar.

Worked example

Eid al-Adha 2026 is calculated for around May 26.

Interpreting your result

This is a calculated approximation — the real date (and the Hajj dates around it) is confirmed by Saudi Arabia's own moonsighting/lunar observation process and may differ by a day.

Recommendations

• Eid al-Adha falls roughly 70 days after Eid al-Fitr on the Hijri calendar.

Frequently asked questions

The underlying Hijri date (10 Dhu al-Hijjah) is the same, but since it depends on moon sighting, some countries may observe it a day apart from Saudi Arabia's own announcement.
