The raw data is based on population estimates from the year 2000 to 2020.

An Eclipse Never Comes Alone!

A solar eclipse always occurs about two weeks before or after a lunar eclipse.

Usually, there are two eclipses in a row, but other times, there are three during the same eclipse season.

All eclipses 1900 — 2199

This is the second eclipse this season.

First eclipse this season: April 4, 1977 — Partial Lunar Eclipse
