The name

Why it is called the Worm Moon

Worm Moon is the March name in American almanacs. It points to the thaw: as frozen ground softens, earthworm casts show on the surface again and birds start to work the lawns, so the Moon of that month took the worms' name.

Crow Moon, Sap Moon and Lenten Moon are other names for the same full Moon, after returning crows, running maple sap and the weeks before Easter. The Anglo-Saxon list gives Rethe Moon for March, and the modern revival list calls it the Moon of Winds.

In the sky

How the Worm Moon looks

A full Moon in March sits near the middle of its yearly range. It comes up close to due east at sunset and climbs on a slope like the Sun's on an equinox day, reaching about 50 degrees at 40 degrees north and staying up for around 12 hours. Low down it picks up the orange tint any low Moon has, because its light crosses a long path through damp, dusty spring air.

The jumbo look of a Moon on the horizon is a trick of comparison, not size. Photograph it near the ground and again high up, and the two pictures show the same width, about half a degree. March is also the month when thaw and haze can blur the edge of the disc while it is low.

In the south March opens autumn, so this Worm Moon belongs with falling leaves, not thaw. Its path lies near the celestial equator, so it climbs to the same height as the equinox Sun at noon, about 55 degrees at 35 degrees south.
