Every year, Muslims watch the sky for the crescent moon that announces Dhul Hijjah and Eid al-Adha, but for 2026 the timing carries a twist: the festival could land on May 26 or May 27 depending on local moon-sighting decisions. This guide explains why the dates differ, what’s known and what’s not, and how to prepare.

Five key facts, one pattern: the date uncertainty is built into the lunar calendar. Here’s what we know.

What are the two possible dates for Eid al-Adha 2026?

Predicted date based on astronomical calculations

  • Astronomical projections indicate Dhul Hijjah will likely begin on the evening of either May 18 or May 19, 2026 (Moonsighting.com).
  • If the month starts on May 18, Eid (10 Dhul Hijjah) lands on May 27; if on May 19, it shifts to May 28. However, because Islamic days begin at sunset, the first full day on the Gregorian calendar can appear as May 26 or 27. Islamic Relief UK predicts Wednesday 27 May 2026 (Islamic Relief UK (charity organization)).

Date subject to moon sighting

  • Local moon-sighting authorities decide the start of Dhul Hijjah based on crescent visibility. This can differ from astronomical predictions (Tarbiyyat (Ahmadiyya UK)).
  • Regions may celebrate on different days: South Asian communities often follow local sightings, while others align with Saudi Arabia’s announcement (Encyclopaedia Britannica).
The catch

Planning a single-day event? The two-date split means you may need to prepare for either day, especially in countries that follow their own moon sighting.

The implication: uncertainty is baked into the lunar system, so flexibility is the only constant.

Is Eid day confirmed in 2026?

No, Eid al-Adha is never confirmed far in advance. The date becomes official only after the crescent of Dhul Hijjah is sighted, typically 2-3 days before Eid (Moonsighting.com).

When is Eid al-Adha usually confirmed?

  • Announcements come on the evening of the 29th of Dhul Qa’dah — roughly May 16-18, 2026 — after a sighting attempt.

How is the date determined?

  • Traditionally by naked-eye sighting of the crescent moon; some regions use astronomical calculations as a guideline (Encyclopaedia Britannica (Islamic calendar)).

The trade-off: The lunar calendar ties worship to observation, which means precision remains out of reach until the last moment.

How many days holiday for Eid al-Adha 2026?

Number of days of celebration

  • Eid al-Adha is celebrated over 3 days (10-13 Dhul Hijjah). The first day is the main feast, followed by two additional days of celebration (Encyclopaedia Britannica).

Number of days of public holiday in different countries

  • In many Muslim-majority countries, the public holiday lasts 3-4 days. Saudi Arabia typically grants a 4-day break, while Pakistan and Bangladesh observe 3 days (Wikipedia).
  • In non-Muslim-majority countries, Muslims often use annual leave for the festival.

The pattern: longer public holidays in Muslim-majority countries offer more celebration time, but expatriates often need to plan personal leave.

How long until Eid al-Adha 2026?

Countdown to Eid al-Adha 2026

As of January 2025, Eid al-Adha 2026 is approximately 510 days away (Timeanddate date calculator).

Current date relative to Eid

With the predicted start date of May 26, 2026, the countdown will shorten after Eid al-Fitr 2026, which falls around April 2026.

The consequence: early planning is possible for Qurbani bookings, but finalizing dates must wait.

What is Eid al-Adha?

The story of Ibrahim and Ismail

Eid al-Adha commemorates the willingness of Prophet Ibrahim (Abraham) to sacrifice his son Ismail as an act of obedience to God. According to Islamic tradition, God provided a ram as a substitute at the last moment (Encyclopaedia Britannica).

The significance of Qurbani

The festival’s central ritual is Qurbani (animal sacrifice), which symbolizes Ibrahim’s devotion. The meat is divided into three parts: one for the family, one for relatives and friends, and one for those in need (Islamic Relief UK).

How Eid al-Adha is celebrated

  • Muslims attend special Eid prayers at mosques or open grounds.
  • Families gather for festive meals, exchange gifts, and give charity (Zakat al-Fitr) (Muslim Aid).
  • The festival coincides with the Hajj pilgrimage in Mecca.

The takeaway: the festival’s roots in sacrifice and charity remain consistent, regardless of the calendar date.

Why this matters: Muslims planning Qurbani should prepare for both dates and rely on official moon sighting announcements in early May 2026.

Timeline for Eid al-Adha 2026

  • April 2026: Ramadan ends (Eid al-Fitr)
  • Early May 2026: Dhul Hijjah month begins (estimated May 18 or 19) (Moonsighting.com)
  • May 26-29, 2026: Eid al-Adha period (CalendarDate.com)
Why this matters

For Muslims in non-majority countries, requesting leave for both potential dates is a practical move, as a one-day shift can affect travel and family gatherings.

What we know and what remains uncertain

Confirmed facts

  • Eid al-Adha falls on 10 Dhul Hijjah 1447 (Encyclopaedia Britannica)
  • Qurbani is required for those who can afford it (Islamic Relief UK)

What’s unclear

  • Exact Gregorian date (May 26 or May 27) pending moon sighting (Moonsighting.com)
  • Whether all countries will celebrate on the same day (Tarbiyyat (Ahmadiyya UK))

How to prepare for Eid al-Adha 2026

  1. Mark both May 26 and May 27 on your calendar.
  2. Monitor official moon-sighting announcements in early May 2026.
  3. Plan Qurbani bookings with flexible dates.
  4. Request holiday leave for both potential dates if necessary.
  5. Wait until the last week before Eid to confirm travel and gatherings.

For Muslims planning Qurbani and holiday schedules for 2026, the strategy is clear: mark both May 26 and May 27 on the calendar, then follow official moon-sighting announcements in early May 2026. Waiting until the last week before Eid to confirm plans is the only reliable approach, or risk celebrating a day early or late.
