Eid al-Fitr is one of the most important festivals in Islam, marking the end of the holy month of Ramadan.
It is celebrated by Muslims around the world with special morning prayers, family gatherings, festive meals and acts of charity.
The exact date changes each year because it depends on the sighting of the new crescent moon, with religious authorities expected to confirm when the festival will take place.
In the UK and elsewhere, communities are currently waiting for an official announcement to determine whether Eid will fall on Friday or the following day.
