A full moon occurs when the Sun and the Moon are on opposite sides of the Earth at the same time. Occurring on a 29.53-day cycle, the full lunar phase in each month is known by many different names depending on the culture or religion.

The full moon in March is generally referred to as the Lenten Moon, as it occurs during the season of Lent observed by the Catholic Church. It is usually the last full moon of winter.

This full moon was known as the Worm Moon by Algonquian Indians of North America, as this is when earthworms first become active after winter in the northern hemisphere. It has also been dubbed the Crow Moon, Magpie Moon, Crust Moon, Sugar Moon, Sap Moon, Chaste Moon, and the Death Moon.

Buddhists refer to the March full moon as Medin Poya while Hindus call it Basanta Poornima.
