2021 Full Moon Calendar

The full moon shows its face to Earth about once a month. Well, sort of. 

Most of the time, the full moon isn’t perfectly full. We always see the same side of the moon, but part of it is in shadow. Only when the moon, Earth and the sun are perfectly aligned is the moon 100% full, and that alignment produces a lunar eclipse

And sometimes — once in a blue moon — the moon is full twice in a month (or four times in a season, depending on which definition you prefer). 

This month’s full moon occurs this weekend on Sunday, Mar. 28 at 2:48 p.m. EDT (18:48 UTC), but the moon will appear full the night before and after its peak to the casual stargazer. March’s full moon is sometimes known as the Worm Moon, though it has many other nicknames by different cultures. You can find out what else to see with the March full moon here.
