Lunar Eclipse Predictor
Estimate upcoming lunar eclipse dates based on full moon and lunar node alignment.
Approximate dates based on the Saros cycle. Verify with NASA Eclipse Atlas for precise times and visibility.

How It Works
Lunar eclipses occur when a full moon aligns with the Moon's nodes (the points where the Moon's orbit crosses Earth's orbital plane). The Saros cycle (18 years, 11 days) predicts eclipse recurrence. This tool provides approximate upcoming dates.

Frequently Asked Questions
How often do lunar eclipses occur?
Lunar eclipses occur 1 to 3 times per year on average, but not every full moon produces an eclipse because the Moon's orbit is tilted about 5 degrees relative to Earth's.
What is the Saros cycle?
The Saros cycle is a period of approximately 18 years and 11 days after which eclipse patterns repeat. It has been used to predict eclipses since ancient times.
