The International Astronomical Centre (IAC) this week predicted the start of the Eid Al Fitr for most of the Islamic nations.

The sighting of the crescent moon would be impossible from all the continents on Monday, June 3, because the moon on that day sets before sunset and/or the topocentric conjunction occurs after the sunset, according to the IAC’s official website.

The IAC said that it would be possible to sight the moon only with a telescope in some western parts of the Americas on June 3.

Eye sighting of the moon would be possible in most Arab nations, Asia, Africa, and part of Australia on Tuesday, June 4.

Countries that started Ramadan on Monday are supposed to complete 30 days of fasting by Tuesday, June 4, IAC stated.

Regarding countries that started Ramadan on Tuesday, May 7, including Brunei, India, Pakistan, Bangladesh, Iran, Oman, and Morocco will complete 29 days of fasting.

They will be able to spot the crescent on June 4, making Wednesday, June 5, the first day of Eid Al Fitr, IAC noted.
