What Is the Worm Moon?

The Worm Moon is the full moon of March in the traditional North American full moon calendar. It follows the Snow Moon in February and precedes the Pink Moon in April, and it falls close to the spring equinox, when the Northern Hemisphere shifts from winter toward spring.

Like every full moon, it occurs when the Moon sits opposite the Sun in the sky and its entire Earth-facing side is lit. The name is a seasonal marker rather than an astronomical category.

Why Is It Called the Worm Moon?

The most widely cited origin is the thawing of the soil. As March temperatures rise, frozen ground softens, and earthworms become active again, leaving their casts on the surface. Birds return to feed on them, and the sight of both marked the arrival of spring. The name is attributed to Native American tradition and entered Colonial American usage through the Old Farmer's Almanac.

A more recent revision points to a different animal. Some accounts hold that the 'worms' in the name were beetle larvae, which emerge from bark and wood as the weather warms. Under this reading, the name refers to the larvae that appear on tree trunks and in dead wood at the end of winter.

What Are the Other Names for the Worm Moon?

March's full moon is known by several names across cultures and almanacs, most of them describing the end of winter.

• Sap Moon — for the flow of maple sap as nights stay cold and days warm
• Crow Moon — for the return of crows and their calls at the end of winter

What Is the Spiritual and Astrological Meaning of the Worm Moon?

The Worm Moon is commonly associated with renewal and awakening. The return of life to frozen ground makes it a traditional symbol of beginnings, and it is often linked with clearing away the old to make room for growth.

Astrologically, the 2026 Worm Moon occurs in Virgo, an Earth sign ruled by Mercury and associated with order, practicality, health, and attention to detail. A full moon in Virgo is traditionally linked with routines, work, and refinement. Because the Sun is in Pisces at the same time, the Virgo–Pisces axis emphasizes the balance between structure and intuition.

How Is the Worm Moon Connected to the Spring Equinox?

The Worm Moon is the full moon closest to the March equinox, when day and night are close to equal in length. The equinox falls on March 20 in 2026, about two and a half weeks after the Worm Moon.

The date of the equinox shapes the seasonal sequence of full moons. The full moon on or after the equinox is the Paschal Full Moon used to calculate Easter, which in 2026 is the Pink Moon in April. In spring, the waxing Moon climbs a steeper path through the evening sky, which makes early crescents easier to see after sunset.
