The Supreme Court of Saudi Arabia has asked its citizens to keep an eye out for the crescent moon on Tuesday, which, if sighted, will mark the beginning of the month of Ramadan on Wednesday. 

If the Ramadan moon is not sighted on Tuesday, the month of fasting will begin on Thursday. 

Saudi Arabia has called on Muslims to immediately report the sighting of the crescent moon with a court or an authority, Arab News reported.
