Pakistan, March 19 -- The International Astronomy Centre confirmed that the Shawwal crescent moon will be impossible to sight on March 29. This is due to the moon setting before the sun, making it unobservable across the Arab and Islamic world. As a result, authorities in these regions have stated that Ramadan will likely last 30 days.

For countries that require an actual moon sighting to begin Shawwal, Eid al-Fitr will likely fall on March 31. However, in some areas, where the conjunction occurs before sunset, the moon may be visible after sunset. These regions may choose to celebrate Eid on March 30 instead.

A partial solar eclipse will also occur on March 29, visible in parts of the western Arab world, including Mauritania and Tunisi...
