Eid Al Fitr will fall on May 2 in most countries where Ramadan started on April 2, according to the UAE-based International Astronomy Centre (IAC).
In a statement carried by UAE news agency Wam, IAC director Shawkat Odeh said it would be impossible to sight the crescent moon on April 30 as the moon will set before the sun.
Thus countries which started fasting on April 2 will conclude Ramadan on May 1 and mark Eid Al Fitr on May 2, it said.
Meanwhile, countries that started fasting on April 3, such as Pakistan, Bangladesh, Indonesia, Malaysia, Brunei, India, Oman, Jordan and Morocco, will sight the crescent moon on May 1 – which will mark the 29th day of Ramadan for them – to determine when the first day of Eid Al Fitr is.
Eid celebrations start at the end of Ramadan which lasts 29 or 30 days, based on when the crescent moon is sighted.
