The first day of Eid al-Fitr is determined by the sighting of the crescent moon marking the start of the month of Shawwal, the 10th month of the Islamic (Hijri) calendar.

Lunar months last between 29 and 30 days so Muslims usually have to wait until the night before Eid to verify its date.

After sunset prayers on Monday, April 8, the 29th day of Ramadan, moon sighters will face west with a clear view of the horizon for a first glimpse of the crescent moon. If the new moon is visible, then the next day will be Eid, if not, Muslims will then fast one more day to complete a 30-day month.
