According to the authorities, the moon-sighting committees had not not received any evidence, the Muslim festival would be celebrated in Saudi Arabia and UAE on Sunday.
A noted UAE astronomer had predicted last week that Eid Al Fitr will fall on Sunday 19th August.
Astronomers had said the crescent moon marking the commencing of the month of Shawwal would rise on Friday 17th August at 7.54pm.
As the moonrise takes place 65 minutes after the sunset on that day, it will be impossible to see it because it will not be there on the horizon.
The ideal time to watch the crescent-shaped moon ranges between 10 to 30 minutes after the sunset on a day.
Thus, they added, the Saturday will be the 30th day that completes the month of Ramadan, and the crescent will be visible on the horizon 17 minutes after the sunset.
