About Eid al-Fitr

Eid al-Fitr (the Festival of Breaking the Fast) marks the end of Ramadan and the beginning of Shawwal, the 10th month of the Islamic calendar. It is one of the two major Islamic holidays (the other being Eid al-Adha).

The celebration begins with a special congregational prayer (Salat al-Eid) performed in the morning. Muslims dress in their finest clothes, give charitable donations (Zakat al-Fitr), and gather with family and friends for festive meals.

Eid al-Fitr falls on the 1st of Shawwal and is determined by the sighting of the new crescent moon after the completion of Ramadan. The date varies by 1-2 days across different countries depending on local moon sighting conditions.

How These Predictions Work

Predictions are based on astronomical calculations using NASA JPL DE421 ephemeris data combined with a machine learning model (Random Forest) trained on over 2,000 historical crescent moon sighting observations. The model evaluates five key parameters — moonset lag, moon age, altitude, elongation, and illumination — to produce a confidence score for crescent visibility at each location.
