Lunar eclipses from 2026 to 2030. Through 2027 the list follows NAOJ’s Rekiyōkō; later years come from NAOJ’s eclipse database (dates and visibility near Japan). Like NAOJ, it leaves out penumbral eclipses, when the Moon only dims slightly. For where else an eclipse can be seen, see NASA’s future eclipses page.
What is a lunar eclipse?
The Sun, Earth and Moon line up in that order, and the Moon passes into Earth’s shadow. It happens only at full moon. In a partial eclipse, part of the Moon is in the shadow; in a total eclipse, all of it is. During totality the Moon does not go black but turns a dark coppery red, because a little red light bends through Earth’s atmosphere and reaches it.
Example: total lunar eclipse of Tue, Mar 3, 2026 (Tokyo, JST)
| Begins | Totality begins | Maximum | Totality ends | Ends |
|---|---|---|---|---|
| 18:49.8 | 20:04.0 | 20:33.7 | 21:03.4 | 22:17.6 |
Times in hours:minutes (JST) from NAOJ’s Rekiyōkō; magnitude 1.156. A lunar eclipse happens at the same moment everywhere; you can see it if the Moon is above your horizon then.
How to watch
You can watch a lunar eclipse safely with your eyes alone whenever the Moon is up. Binoculars show the moving shadow and the color change better.
