how often are lunar eclipses

Lunar eclipses happen a few times most years, but any one place on Earth only sees a total lunar eclipse every couple of years or so on average.

How often are lunar eclipses?

  • Globally, there are about two lunar eclipses per year on average (counting penumbral, partial, and total).
  • In rare years there can be up to five lunar eclipses.
  • In a specific location, a total lunar eclipse is visible roughly once every 2–3 years on average.

By type

  • Total lunar eclipses (the classic “Blood Moon”) make up a bit over one‑third of all lunar eclipses, so they are less common than the others.
  • Partial lunar eclipses are also fairly common and occur about once a year or once every two years if you count only “pure” partial events.
  • Penumbral eclipses (very subtle dimming) fill in the rest of the events.

A simple way to picture it: the Earth, Moon, and Sun line up well enough for a lunar eclipse only during short “eclipse seasons” a bit less than six months apart, and not every full Moon in those seasons produces a dramatic total eclipse.

TL;DR: On Earth as a whole, expect around two lunar eclipses every year , sometimes more, but a total lunar eclipse from your own backyard only every few years on average.
