Confidence reflects the likelihood of crescent moon visibility on the evening before the predicted date. Higher confidence means stronger astronomical conditions for sighting.

Eid al-Adha (the Festival of Sacrifice) is the holiest of the two major Islamic holidays. It falls on the 10th of Dhul Hijjah, coinciding with the annual Hajj pilgrimage to Makkah. It commemorates Prophet Ibrahim's (Abraham's) willingness to sacrifice his son in obedience to God.
Muslims who can afford it sacrifice an animal (typically a sheep, goat, cow, or camel) and distribute the meat among family, friends, and those in need. The holiday begins with a special congregational prayer and typically lasts 3-4 days.
The date of Eid al-Adha is determined by the start of Dhul Hijjah, which depends on crescent moon sighting. Eid al-Adha falls on the 10th day of Dhul Hijjah, nine days after the month begins.
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.
