Eid al-Adha 2027 is expected on Sunday, May 16, 2027 under the Saudi Umm al-Qura calendar, and on Monday, May 17 for communities that begin Dhul Hijjah by local moon sighting. In the USA, both dates are in use, so confirm with your local masjid.
What Is the Eid al-Adha 2027 Date?
Eid al-Adha falls on the 10th of Dhul Hijjah, the last month of the Islamic calendar. In 2027, that’s 10 Dhul Hijjah 1448 AH.
- Sunday, May 16, 2027: the calculated Umm al-Qura date, which can move a day either way once the moon is sighted.
- Monday, May 17, 2027: the date many US calendars list as tentative, and the date for communities that start the month a day later.
Eid is a daytime celebration. The Eid prayer happens in the morning of the 10th, not the evening before.
Eid al-Adha 2027 Dates at a Glance
| Event | If you follow calculation (Saudi/Umm al-Qura) | If you follow local sighting |
| 1 Dhul Hijjah | Fri, May 7 | Sat, May 8 |
| Hajj rites begin (8th) | Fri, May 14 | Sat, May 15 |
| Day of Arafah (9th) | Sat, May 15 | Sun, May 16 |
| Eid al-Adha (10th) | Sun, May 16 | Mon, May 17 |
| Days of Tashreeq (11th–13th) | May 17–19 | May 18–20 |
Sources: Umm al-Qura-based dates for Dhul Hijjah 1448 and Eid, Hajj-rite timing and the possibility that sighting-based countries observe Eid a day later, and Arafah on Saturday, May 15. The “local sighting” column shifts each date one day later, which is how that method works.
Why Do US Communities Celebrate Eid on Different Days?
Because Islamic months start with the new crescent moon, and people agree on that goal but not on the method.
Moon sighting vs. calculation
- Calculation uses astronomy to set the month in advance. Saudi Arabia’s Umm al-Qura calendar is the best-known example.
- Local sightings wait for someone to actually see the crescent, then start the month.
- Global sighting accepts a sighting anywhere in the world.
Each method is followed sincerely by real communities. The Gregorian date can differ by a day, and that’s the only difference.
The Eid moon facts for 2027
The new moon (astronomical conjunction) happens on May 6, 2027, at about 11:00 UT. That’s roughly 7:00 a.m. Eastern. By sunset in the US, the moon will be well under a day old.
One UK-based moon predictor says the crescent won’t be visible to the naked eye anywhere from the UK to Morocco that evening. That’s a major reason sighting-based communities may begin Dhul Hijjah a day after the calculated date.
What your US organizations may follow
- The Fiqh Council of North America has adopted a position on using astronomical calculations for the start of Islamic months.
- ISNA, CAIR chapters, and local masjids each announce their own calendars. One CAIR chapter’s published calendar lists Eid al-Adha on Sunday, May 16, 2027.
- Your masjid has the final say for your community. If it hasn’t been announced yet, it will, usually in the days before.
I couldn’t find an official FCNA announcement for May 2027 yet, so check back in spring.
The Eid Date Confidence Ladder
A date isn’t simply “known” or “unknown.” It climbs a ladder. Knowing which rung you’re on helps you plan without stress.
- Calculated (now): an estimate based on astronomy or tabular calendars. One calendar site calls its own date a planning reference, not religious confirmation.
- Announced (early May): national or regional bodies announce the start of Dhul Hijjah around May 6–7, 2027.
- Confirmed by your masjid (days before): the date your local community will actually observe.
The plan-for-both-days rule: until you reach rung 3, pencil in both May 16 and May 17. Ask about leave for Monday, and tell the family you’ll confirm. It costs nothing, and it beats scrambling.
Editor’s note: add a short quote or scenario here from a real imam, masjid administrator, or family about how your community decides its date. Don’t publish an invented one.
When Is the Day of Arafah in 2027?
The Day of Arafah is the 9th of Dhul Hijjah, the day before Eid. In 2027 it’s expected on Saturday, May 15 (calculation) or Sunday, May 16 (local sighting).
It’s the central day of Hajj, when pilgrims gather at Mount Arafah. Many Muslims who aren’t on Hajj choose to fast that day. Fasting on Eid itself is not permitted, so don’t carry the fast over.
When Does Dhul Hijjah Start in 2027?
Dhul Hijjah 1448 is expected to begin Friday, May 7, 2027 under the Umm al-Qura calendar, or Saturday, May 8 for communities that sight the moon locally.
The first ten days are among the most spiritually significant of the year. Many people increase prayer, charity, and remembrance of Allah, and those planning Qurbani follow certain guidelines about hair and nails. Ask a scholar about specifics for your situation.
Planning Around Eid in the US: Work, School, Travel
Check your calendar early. Eid lands on a Sunday or Monday in 2027, just two weeks before Memorial Day (May 31). A Monday Eid means many people will need to request time off.
- It’s not a federal holiday. Employers aren’t required to give the day off, so request leave early. Verify with your employer’s policy or OPM.
- California has moved on this. A September 2026 report says the state now recognizes both Eids as state holidays. Read the official text to see what it means for employers and schools before you rely on it.
- School finals and graduations often cluster in mid-May. If you have students, talk to teachers and administrators early about an excused absence.
- Travel: if you’re flying to family, a Sunday/Monday pair means the weekend before is the busy one. Book with a flexible plan until your date is confirmed.
Qurbani in 2027 Windows and US Realities
Qurbani (the sacrifice) is a central act of Eid al-Adha. It can be offered on Eid and the three days of Tashreeq that follow, four days in total, ending at sunset on the 13th of Dhul Hijjah.
In the USA, many people don’t slaughter at home, since local rules and practicalities make that hard. Instead they:
- Use a halal slaughterhouse or local farm arranged by their masjid.
- Give through a trusted charity that carries out Qurbani and distributes the meat abroad or locally.
Whichever you choose, order ahead. Spots and delivery windows fill up as Eid approaches.
Eid al-Adha vs. Eid al-Fitr in 2027
| Eid al-Fitr | Eid al-Adha | |
| Marks | End of Ramadan | Ibrahim’s devotion, linked to Hajj |
| Month | 1 Shawwal | 10 Dhul Hijjah |
| 2027 date (expected) | Tuesday, March 9 | Sun, May 16 / Mon, May 17 |
| Also called | The “Smaller Eid” | The “Greater Eid” cair |
The Islamic year is about 11 days shorter than the Gregorian one, so both Eids arrive roughly 11 days earlier each year. That’s also why Eid al-Adha moves around the Gregorian calendar.
Conclusion
Eid al-Adha 2027 in the USA is expected on Sunday, May 16, 2027 (10 Dhul Hijjah 1448 AH), and most calendars list this date. However, the final date depends on moon sighting. Dhul Hijjah may begin on May 7 or 8, which puts Eid on Sunday, May 16 or Monday, May 17. If the crescent is not sighted in your area on the evening of May 6, Eid would fall on Monday, May 17. The safest wording for your article is “expected Sunday, May 16 (Monday, May 17 possible).
