Europe's diverse latitudes, from Istanbul in the southeast to Stockholm in the north, create significantly different crescent visibility windows. Northern European cities face particular challenges during summer months when twilight can persist for hours.
With growing Muslim communities across the United Kingdom, France, Germany, the Netherlands, and beyond, accurate Hilal predictions serve millions. Our system accounts for each city's precise coordinates and timezone to deliver reliable forecasts for Islamic month determinations.
Our system calculates five key astronomical parameters at sunset: moonset lag, moon age, moon altitude, sun-moon elongation, and illumination percentage. These are fed into a machine learning model trained on over 2,000 historical crescent sighting observations to produce a confidence score from 0% to 100%.

Moon Age
