Astronomical calculations conducted by the Department of Astronomical Affairs at the Ministry of Awqaf and Religious Affairs on the visibility of the moon of the month of Shawwal on the evening of Saturday, 29th Ramadan 1438 AH, which corresponds to June 24 in the city of Muscat, shows the following: As the moon will be in the conjunction phase in Muscat at 6:31 am and the moon will descend at 7:15 pm.

The sun sets at 6:57 pm. This means that the moon will descend after sunset by about 18 minutes and the height of the moon will be three degrees. 

Therefore, sighting the moon on this day is very difficult and almost impossible.
