Saros Eclipse Predictor
Synodic · Draconic · Anomalistic Resonance
An eclipse occurs when the Sun, Earth, and Moon align near a lunar node. The Saros cycle (223 synodic months ≈ 18 yr 11.3 d) captures the simultaneous resonance of three lunar months — predicting when the same eclipse geometry will recur.
