Penumbral Lunar Eclipse on March 31, 1904 - Online Full Moon Eclipse Calendar

The periodicity and recurrence of lunar eclipses is governed by the Saros cycle.
Saros cycle is a period of approximately 6,585.3 days (18 years 11 days 8 hours). When two eclipses are separated by a period of one Saros, they share a very similar geometry. The two eclipses occur at the same Lunar Node with the Moon at nearly the same distance from Earth and at the same time of year. Saros series returns to about the same geographic region every 3 saroses (54 years and 34 days).
This 3 saroses period is called exeligmos (turning of the wheel). Eclipses in the same exeligmos period as March 31, 1904 eclipse are marked with highlighted background.
