How often are total lunar eclipses?
Why isn’t there a lunar eclipse every month? A lunar eclipse only occurs during a full Moon, when the Sun, Earth and Moon are all aligned. But despite the Moon only taking 29.5 days to orbit Earth and complete a cycle from full Moon to full Moon, there are only on average about three lunar eclipses every year.

The moon is fully in the Earth’s shadow and this is why it is a total lunar eclipse.
How many years are there between lunar eclipses?
Over the course of the next 2 centuries, a total lunar eclipse occurs every 18.031 years (= Saros), as the Moon is displaced progressively southward through the umbral shadow with each eclipse. Halfway through this period, the Moon passes through the center of the umbra producing long total eclipses.
What happens every 54 years?
For solar eclipses, this results in the shifting of each successive eclipse path by ~120º westward. Thus, a Saros series returns to about the same geographic region every 3 saroses (54 years and 34 days). The last central eclipse of the series occurs near the north pole.
How many eclipses occur each year?

What is the frequency of a lunar eclipse?
Frequency of occurrence. Since the occurrence of lunar and solar eclipses depends on the specific alignment of the Sun, earth and Moon in the same plane, total eclipses do not occur very frequently. Usually, lunar eclipses (different types) occur about twice a year or more, whereas solar eclipses (varying types) occur three to four times a year.

What is the eclipse of the Moon?
There are 7 stages of a total lunar eclipse: Penumbral eclipse begins: This begins when the penumbral part of Earth’s shadow starts moving over the Moon. Partial eclipse begins: Earth’s umbra starts covering the Moon, making the eclipse more visible. Total eclipse begins: Earth’s umbra completely covers the Moon and the Moon is red, brown, or yellow in color.
