Arab countries will likely differ in determining the dates of Eid al-Fitr 2025 for the following reasons:

Arab Weather - The Arab and Islamic world, including Jordan and Saudi Arabia, will observe the crescent moon of Shawwal (Eid al-Fitr) this year after sunset on Saturday, Ramadan 29, 1446 AH, corresponding to March 29, 2025 AD.

It is not possible to see the Shawwal crescent on Saturday evening, but...

Astronomical calculations indicate that the central conjunction will occur at 1:58 pm on Saturday, Mecca time, and the crescent will remain on the horizon after sunset for only 7 minutes. The age of the crescent at the start of observation will be 4 hours and 37 minutes, which is a very young age that cannot be seen with the naked eye, despite the birth of the crescent and the beginning of the new month astronomically, but...

Extrapolation from the past gives different results!

Although sighting the crescent moon is not possible according to astronomers, extrapolating from the past yields different results. In 2019, four people in Saudi Arabia testified that they saw the crescent moon with the naked eye. The crescent was 5 hours and 58 minutes old, and remained after sunset for only 6 minutes! Therefore, legal sighting will remain the deciding factor for countries that require legal sighting. Countries that rely on the astronomical date of the crescent moon will declare Sunday the first day of Eid al-Fitr, and God knows best.
