Worm Moon

March's full moon, marking the first thaw and the return of life to the soil.


The next Worm Moon is full on Monday, March 22, 2027 at 09:34 UTC.

Why it's called the Worm Moon

As the ground thawed in March, earthworm casts reappeared in the softening soil and earthworms drew robins — so the spring's first full moon became the Worm Moon.

March's full moon marks the thaw. The older reading points to earthworms returning to warming earth; a newer one notes the beetle larvae that emerge from bark as winter loosens. Either way, it is the moon of the ground coming back to life.

Other names track the same season: the Sap Moon, for the rising of maple sap, and the Crow Moon, for the cawing that announces winter's end. Falling near the spring equinox, it is also the Lenten Moon of the Christian calendar.

March's full moon is also known as the Sap Moon, the Crow Moon, the Lenten Moon.

Watching the Worm Moon


A full moon rises in the east around sunset and stays up all night, setting near sunrise — so any clear evening close to Mon, March 22 you can watch it climb once it gets dark. It looks biggest and most golden in the first hour after it rises, sitting low on the horizon.

Photographing it? A full moon is flatly lit and shows little crater relief — frame it against a landscape, hills or skyline just after moonrise for scale and warm colour. For sharp crater detail, shoot a night or two before or after full, when shadows return along the terminator.
