Is the date shown the official, confirmed date?

No. The date shown is a widely published calculated estimate based on astronomical prediction of the new moon. The actual start of Eid al-Adha is confirmed only by an official moon sighting shortly before the holiday, and it can shift by a day earlier or later than the calculated estimate.

Why does Eid al-Adha fall earlier each year?

Eid al-Adha follows the Islamic lunar (Hijri) calendar, which is about 354 days long, roughly 10 to 11 days shorter than the Gregorian solar year. That difference causes the Gregorian date to shift earlier each cycle.

How long is Eid al-Adha celebrated?

Eid al-Adha is typically observed over 3 to 4 days, starting on 10 Dhul Hijjah. This tool counts down to the first day.

What time zone does the countdown use?

The countdown uses your device's local date and time, so it reflects your own timezone automatically.

What if today IS the first day of Eid al-Adha?

The tool shows that Eid al-Adha has started today and how many days remain in the multi-day observance.

Are dates available beyond 2031?

The tool currently covers 2025 through 2031. Dates further out carry more calculation uncertainty and will be added as estimates are published.

Summary

This tool calculates the number of days remaining until the next Eid al-Adha, using widely published calculated Gregorian date estimates for each year from 2025 to 2031. Eid al-Adha falls on the 10th day of Dhul Hijjah, the final month of the Islamic lunar calendar, so its Gregorian date shifts roughly 10 to 11 days earlier every year. The countdown updates automatically based on your local date.
