Moon Sighting in the Americas

The Americas span from northern Mexico to southern Argentina, creating vastly different crescent moon sighting conditions. Equatorial cities like Cali and Barranquilla often enjoy favorable year-round visibility, while southern cities like Buenos Aires and Santiago experience more seasonal variation.

Growing Muslim communities across Latin America and the Caribbean rely on accurate Hilal predictions for determining Islamic month start dates. Our system provides precise calculations for each city, accounting for local sunset and moonset conditions across multiple time zones.

How Our Predictions Work

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%.
