Muslims across the UK await Saudi Arabia’s Eid Al-Adha 2026 moon sighting announcement as experts predict exactly when the celebrations could begin later this month
Muslims around the world are preparing for the Eid Al-Adha 2026 moon sighting, with astronomers predicting the Dhul Hijjah crescent could be visible in Saudi Arabia, the UAE and parts of the UK later this month.
The crescent moon, which marks the start of the Islamic month, could be visible on the evening of May 17, astronomers say, though the exact date will depend on confirmed sightings. If the moon is seen, Dhul Hijjah – the final month of the Islamic calendar – would begin on May 18, placing Eid Al-Adha on or around May 27.
Eid al-Adha is one of the most important festivals in Islam and is usually celebrated over three days.
Muslims typically attend special prayers, spend time with family and friends, share meals and give to charity, while many also mark the occasion with the ritual sacrifice of an animal, with meat often distributed to those in need.

When will Dhul Hijjah moon be visible in Saudi Arabia?
Saudi Arabia is expected to carry out the official moon sighting for Dhul Hijjah on the evening of May 17, 2026.
The Kingdom’s moon sighting committees will look for the crescent shortly after sunset, with astronomers suggesting viewing conditions could be favourable in parts of the Middle East.
If the crescent is confirmed, May 18 would become the first day of Dhul Hijjah. Eid Al-Adha takes place on the 10th day of that month, so would likely begin on May 27.
If the moon is not sighted, the Islamic month of Dhul Qa’dah would complete 30 days, pushing Eid back by one day.
Could the Eid Al-Adha 2026 moon be seen in the UK?
Some Muslims in the UK follow moon sightings announced by Saudi Arabia, while others might rely on local sightings.
Weather conditions can affect whether the crescent is seen in Britain, meaning communities can sometimes begin Islamic months on different dates.
Experts say the crescent moon may be difficult to spot with the naked eye in parts of the UK on May 17, but telescopes and clear skies may improve visibility.
Mosques and Islamic organisations across Britain are expected to issue guidance closer to the expected sighting date.
Why do Eid dates differ around the world?
Eid dates can vary because different countries and Islamic authorities use different methods to determine the start of the lunar month.
Some rely strictly on physical moon sightings, while others use astronomical calculations to predict when the crescent should be visible.
This means Saudi Arabia, the UAE, Pakistan, Morocco and the UK can sometimes announce the beginning of Dhu al-Hijjah on different days.
