The sighting of the Shawwal moon would mark the end of the holy month of Ramadan and the beginning of Eid Al Fitr.

If the moon is sighted on Monday, the month of Ramadan would end on its 29th day, while Eid Al Fitr will fall on Tuesday. If the moon is not sighted, the holy month would end with 30 days, and Eid will fall on Wednesday.
