New York City, home to one of America's largest and most diverse Muslim communities, sits at latitude 40.7°N on the eastern seaboard. The city's position means it typically experiences earlier sunsets compared to western US cities, which can affect the moonset lag — a critical factor in crescent visibility.
Our predictions for New York City account for the specific astronomical conditions at this location, including sunset and moonset times in the Eastern timezone. NYC's conditions are often representative of other northeastern US cities.
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%.
