Moon Sighting in Oceania

Oceania presents unique crescent moon sighting conditions, with cities spanning from Perth in Western Australia to Auckland in New Zealand. Southern hemisphere locations experience reversed seasonal patterns compared to the Northern hemisphere, affecting crescent visibility timing.

Muslim communities in Australia, New Zealand, and the Pacific Islands rely on accurate Hilal predictions tailored to their specific locations. Our system accounts for each city's precise coordinates, delivering reliable forecasts for Islamic month determinations in this diverse region.

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%.

Moon Age
