You're probably trying to lock down your holiday plans, book flights, or coordinate family dinners for Eid al-Adha 2026. If you're feeling confused by the conflicting dates floating around online, you aren't alone. One site tells you it's Wednesday, May 27. Another claims it might be Thursday, May 28. Why can't anyone give you a straight answer?
The reality comes down to a sky-watching tradition that's stood for over a thousand years. Everything rests on the official moon sighting announcement from the Saudi Supreme Court.
The court issued an update that changed the timeline for tracking the new crescent moon of Dhul Hijjah. If you want to know when your holiday actually starts and how to prepare without the last-minute panic, let's unpack exactly what's happening on the ground.
The Last Minute Shift in Saudi Arabia
The Saudi Supreme Court changed the date for the official Dhul Hijjah moon sighting to Sunday, May 17, 2026.
Why the sudden change? It traces back to an earlier judicial ruling regarding the start of the current month, Dhul Qadah. The supreme court declared that Sunday, April 19 marked the official start of Dhul Qadah. Based on that timeline, Sunday, May 17 marks the 29th day of the month on the court's calendar, even though the standard civil Umm Al-Qura calendar lists it as the 30th.
The technical calendar tracking doesn't matter as much as the practical result. The highest religious authority in Saudi Arabia is instructing the public and official astronomical observatories—including the famed hubs in Sudair and Tumair—to scan the western horizon on Sunday evening.
They aren't just looking for fun. This observation establishes the calendar for the entire global Islamic community. Anyone who spots the crescent moon with their naked eye or through binoculars is legally requested to head to the nearest local court to register their testimony.
The Two Paths for Your Calendar
The Sunday night moon sighting gives us two concrete timelines. There's no third option, so you can plan around these two scenarios.
Scenario A: The Moon is Sighted on Sunday, May 17
If the sky watchers spot the thin sliver of the crescent on Sunday evening, the current month ends at 29 days.
- Monday, May 18 becomes the official 1st day of Dhul Hijjah.
- Tuesday, May 26 will be the Day of Arafah (the peak of the Hajj pilgrimage).
- Wednesday, May 27 will be the first day of Eid al-Adha.
Astronomical data heavily favors this outcome. Space agencies indicate the new moon will be born well before sunset on Sunday, giving the crescent enough age and altitude to be visible under clear skies.
Scenario B: The Moon is Not Sighted on Sunday, May 17
If dust, clouds, or atmospheric conditions obscure the moon, the current month automatically defaults to a full 30 days.
- Monday, May 18 becomes the 30th day of Dhul Qadah.
- Tuesday, May 19 marks the official start of Dhul Hijjah.
- Wednesday, May 27 becomes the Day of Arafah.
- Thursday, May 28 will be the first day of Eid al-Adha.
Why This Year's Sighting is Unusual for Global Dates
Normally, you see a clear one-day split between the Middle East and South Asian countries like Pakistan, India, and Bangladesh. The moon moves west, so regions further east usually have to wait an extra night to see the crescent.
This year presents a rare synchronization. Because of how the lunar cycle aligns, South Asian moon-sighting committees—including Pakistan’s Central Ruet-e-Hilal Committee meeting in Karachi—are also convening on Sunday, May 17.
What does this mean for you? There's a very high probability that Muslims in London, Riyadh, Karachi, and New York will celebrate Eid on the exact same day. This makes coordinating global family calls and vacation time much easier.
Making Sense of Your Public Holiday Options
If you work or live in a Muslim-majority country, your government has likely already announced provisional dates based on astronomical calculations. They assume Scenario A will play out.
The United Arab Emirates, Qatar, and Saudi Arabia have mapped out generous 4 to 5-day public holiday blocks starting around Tuesday, May 26. Pakistan is preparing for a national holiday window expected from May 27 to May 29.
If your employer requires strict advance notice for annual leave, book your time off based on Scenario A, but keep a floating personal day ready for Scenario B just in case.
The Obligations You Need to Handle Right Now
If you intend to offer the Udhiyah or Qurbani sacrifice this year, the confirmation of the new month triggers specific rules.
Grand Mufti Sheikh Saleh Al-Fawzan reminded believers that once Dhul Hijjah begins, anyone intending to offer a sacrifice should avoid cutting their hair, nails, or trimming their skin until the animal is slaughtered. If the moon is sighted Sunday night, those rules take effect at sunset on Sunday. Get your haircut handled before Sunday evening.
Don't wait until the middle of Eid week to arrange your charity donations or animal selection. High demand during the first ten days of the month causes processing prices to spike, and reputable humanitarian organizations face massive backlogs. Booking your sacrifice early guarantees the distribution happens on the actual days of Eid.
If you aren't traveling for Hajj, your main focus should be on the first nine days of the new month, particularly the Day of Arafah. Fasting on that day expiates the sins of the previous year and the coming year. Mark your calendar for Tuesday, May 26 as your primary spiritual focus point, and prepare your meal plans accordingly.
