Why is easter different every year?

In: Easter
[Edit]
Easter is observed on the Sunday after the first full moon on or after the day of the vernal equinox (where the sun is directly over the equator in the spring of the Northern Hemisphere). Since our calendar is based on the movement of the Earth and not the movement of the Moon, Easter falls on different dates every year. These requirements mean that Easter will always be between March 22 and April 25.
