I didn't realize until I looked it up that "Worm Moon" is a real thing; it''s the old Farmer's Almanac name for the full moon in March. I learned something.
The last Full Moon of the winter season in March is the Worm Moon because of the earthworms that come out when the soil warms up. Native American tribes called it the Crow Moon for the crows coming back, Snow Crust Moon, and Sap and Sugar Moon for when the maple sap runs.
The Anglo-Saxons called it Lenten Moon after the Germanic Lenten for spring. The Celts called it the Wind Moon and Plough Moon. In Old English, it was known as the Death Moon and the Chaste Moon referring to the purity of the spring season.
