How it is calculated
Key dates in 2027
According to the Umm al-Qura calendar, Ramadan begins on Monday, 8 February 2027. Eid al-Fitr falls on Tuesday, 9 March 2027, Eid al-Adha on Sunday, 16 May 2027. The table lists each date in both calendars.
Why there are two dates
The Islamic calendar is purely lunar with 354 or 355 days, so the holidays move about eleven days earlier every year. Saudi Arabia uses the Umm al-Qura calendar; Türkiye’s Diyanet fixes its calendar in advance using astronomical criteria. Many countries and communities, including many in the US and UK, start the month only after the crescent has been sighted – then a holiday can be one day later.
Limits
Islamic days begin at sunset; the nights (Laylat al-Qadr, Isra and Mi’raj) are observed on the evening before the listed day. For prayer times and Eid prayers, follow your local mosque.
