Saros Cycle

by Fred Espenak

The periodicity and recurrence of eclipses is governed by the Saros cycle, a period of approximately 6,585.3 days (18 years 11 days 8 hours). It was known to the Chaldeans as a period when lunar eclipses seem to repeat themselves, but the cycle is applicable to solar eclipses as well.

Additional summary

The remainder explains eclipse recurrence and Saros cycle relationships. It is a strong astronomy seed source because eclipse cycles are a clear, concrete astronomical cycle.
