Cairo, the capital of Egypt at latitude 30.0°N, is one of the most important reference cities for moon sighting in North Africa and the Arab world. The city's generally clear desert skies provide favorable conditions for crescent observation.
As the largest city in the Arab world, Cairo's moon sighting reports influence Islamic calendar determinations across the region. Our system delivers precise predictions based on Cairo's specific astronomical conditions.
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%.
Moonset Lag
≥ 45 min
Moon Age
≥ 21 hrs
Altitude
≥ 8°
Elongation
≥ 10°
Illumination
