Ramadan is the ninth month of the Islamic (Hijri) calendar and is observed by Muslims worldwide as a month of fasting (sawm), prayer, reflection, and community. During Ramadan, Muslims abstain from food, drink, and other physical needs from dawn (Fajr) to sunset (Maghrib).
The start of Ramadan is determined by the sighting of the new crescent moon (Hilal) on the 29th of Sha'ban — the month preceding Ramadan. If the crescent is not sighted, Sha'ban is completed as 30 days and Ramadan begins the following day.
Ramadan commemorates the first revelation of the Quran to Prophet Muhammad (PBUH). It is one of the Five Pillars of Islam and culminates in the celebration of Eid al-Fitr on the 1st of Shawwal.
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.
