Our eclipse predictions use Swiss Ephemeris calculations with 0.1 second accuracy over 2000+ years.
Eclipses occur when lunations happen near lunar nodes (where the Moon's orbit crosses Earth's ecliptic plane).
We predict both solar eclipses (new moon eclipses) and lunar eclipses (full moon eclipses) with precise timing, magnitude, and visibility paths.
The API includes Saros cycle data - eclipse families that repeat every 18 years, 11 days.
Professional astrologers use this for long-term timing work, while apps use eclipse alerts to boost user engagement.
Historical accuracy tests show 99.97% precision compared to astronomical observations.
Unlike basic lunar calendars that miss eclipse nuances, our API delivers complete eclipse metadata including partial/total phases and regional visibility.
