When is Eid al-Adha 2027?

Eid al-Adha 2027 is on Monday, 17 May 2027 — Monday. That is 187 days from today (11 November 2026) — 26 weeks and 5 days, or about 6.1 months. It is a Islamic observance. The exact date depends on moon sighting or the local calendar and can shift by a day.

How the countdown is worked out

The countdown is the number of days from today to the holiday's date: Monday, 17 May 2027 minus 11 November 2026 is 187 days. The count is in calendar days — it counts the days you have to wait, not the number of midnights, and it does not count today. The countdown timer recomputes the number live, second by second, and the days until calculator does the same calculation for any date you choose. If the holiday is in a different time zone from you, the day starts at a different moment — but the date is the date, and the countdown is in days, so the time zone does not change the number.

What is Eid al-Adha?

Eid al-Adha, the Festival of Sacrifice, is the second of the two main Islamic festivals. It falls during the Hajj pilgrimage and commemorates Abraham's willingness to sacrifice his son. Its date depends on the lunar calendar, so it can shift by a day.

How Eid al-Adha is observed

Families attend prayers, share a festive meal and, where it is the custom, sacrifice an animal and share the meat with family and the poor. It is a public holiday across the Muslim world.

How the date is worked out

Eid al-Adha follows a lunar or lunisolar calendar, so its date moves each year and the exact date depends on the moon sighting or the local calendar. The dates on this page are the expected dates; they can shift by a day. For planning travel or time off, confirm the date with an official source for your country — and for religious observance, with your local religious authority.

Eid al-Adha 2027 in the calendar

Eid al-Adha 2027 is the 137th day of 2027 — a year of 365 days — and it falls in ISO week 20 of the year. There are 228 days left in the year after it, and 31 days in May 2027. In the Northern Hemisphere it is spring; in the Southern Hemisphere the seasons are reversed.

The week number matters more than people think: in business and government across Europe, dates are often given as week numbers, and the week number finder gives the ISO week for any date. The day-of-year number is used in astronomy, in logistics and in some payroll systems. And the days-left figure is the useful one for planning the rest of the year: after Eid al-Adha 2027 there are 228 days — 32 weeks — left in 2027.

Planning for Eid al-Adha 2027

187 days is 6 months — plenty of time to plan. If Eid al-Adha means travel, book it now: fares and hotels are usually cheapest months in advance, and the popular dates sell out. If it means time off work, put the request in early, especially if the holiday falls on a weekday — Monday is a working day for most people, so the day off needs to be booked. And if it means gifts or preparations, the countdown is long enough that a little planning each week is worth more than a rush in the last few days.

Eid al-Adha 2027 falls on a Monday — a weekday — so most people need to take the day off to mark it properly. Book the time off early, especially if the holiday is one people travel for: the days around a weekday holiday are among the busiest travel days of the year, and the fares rise as the date approaches.

The countdown in other units

The countdown to Eid al-Adha 2027 is 187 days — which is 26 weeks and 5 days, 4488 hours, 269,280 minutes, or about 6.1 months. Of those 187 days, 133 are weekdays and 54 are weekend days — so if you are counting working days, there are 133 of them left before the holiday. The days between dates calculator works out the same numbers for any two dates, and the business days calculator counts the working days excluding public holidays.

Eid al-Adha around the world

As an Islamic observance, this day follows the Islamic lunar calendar, so its date moves each year and the exact date depends on the sighting of the new moon — it can shift by a day. It is a public holiday across the Muslim world. The lunar calendar is about 11 days shorter than the solar year, so Islamic observances move backwards through the seasons, falling about 11 days earlier each year.
