The full moon for March 2008 will occur at 2.40pm EDT on the 21st. The March full moon is called the “Worm Moon” as the warmer days of spring bring the thawing of the ground, and the birds finally going after earthworms that are beginning to get active.
(Just a note about the time of full moon: the moon is “full” for only a moment, despite what local meteorologists say. This has been discussed before).
This also happens to be the Paschal Full Moon, which is the first full moon of Spring. What is the significance of this? The date of the first full moon after the vernal equinox determines the date of Easter.
This year Easter will be about the earliest it can be, so expect some colder weather. You might have to hunt Easter eggs in the snow.
