About Islamic New Year

The Islamic New Year (also known as Hijri New Year) marks the first day of Muharram, the first month of the Islamic calendar. It commemorates the Hijra — the migration of Prophet Muhammad (PBUH) from Makkah to Madinah in 622 CE.

Muharram is one of the four sacred months in Islam during which warfare was traditionally forbidden. The 10th of Muharram (Ashura) is particularly significant — it is observed as a day of fasting and reflection by many Muslims.

Unlike the Gregorian New Year, the Islamic New Year is generally a quieter observance focused on reflection and gratitude rather than festivities. Some Muslim communities hold special prayers and gatherings.

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.
