March’s full Worm Moon arrives on Sunday, March 28! Here’s all you need to know about the full Worm Moon—including why it has such an odd name.
When to See the Full Moon in March 2021
March’s full Worm Moon reaches peak illumination at 2:50 P.M. EDT on Sunday, March 28, 2021. Look for the spectacularly bright Moon as it rises above the horizon that evening! See when the Moon will be visible in your area.
This year, because it is the first full Moon to occur after the spring equinox on March 20, March’s full Moon is the Paschal Full Moon. This means that its date determines the date of Easter (April 4, 2021)! Read more about how Easter’s date is determined.
Why Is It Called the Worm Moon?
The full Moon names used by The Old Farmer’s Almanac come from a number of places, including Native American, Colonial American, and European sources. Traditionally, each full Moon name was applied to the entire lunar month in which it occurred, not only to the full Moon.
The Worm Moon
March’s full Moon goes by the name Worm Moon, which was originally thought to refer to the earthworms that appear as the soil warms in spring. This invites robins and other birds to feed—a true sign of spring!
An alternative explanation for this name comes from Captain Jonathan Carver, an 18th-century explorer, who wrote that this Moon name refers to a different sort of “worm”—beetle larvae—which begin to emerge from the thawing bark of trees and other winter hideouts at this time.
Alternative March Moon Names
There are quite a few names for the March Moon that speak to the transition from winter to spring. Some refer to the appearance (or reappearance) of certain animals, such as the Eagle Moon, Goose Moon (Algonquin, Cree), or Crow Comes Back Moon (Northern Ojibwe), while others refer to signs of the season:
- The Sugar Moon (Ojibwe) marks the time of year when the sap of sugar maples starts to flow.
- The Wind Strong Moon (Pueblo) refers to the strong windy days that come at this time of year.
- The Sore Eyes Moon (Dakota, Lakota, Assiniboine) highlights the blinding rays of sunlight that reflect off the melting snow of late winter.
March’s full Moon often plays a role in religion, too. Specifically, in Christianity, this Moon is known as the Lenten Moon if it is the last full Moon of the winter season (i.e., if it occurs before the spring equinox) or as the Paschal Full Moon if it is the first full Moon of spring (i.e., if it occurs after the spring equinox).
In 2021, March’s full Moon occurs after the date of the spring equinox (March 20), so it is also the Paschal Full Moon. Read more about the Paschal Full Moon and Easter here.
