Celebrated every year on the first Sunday after the first full moon after the Spring Equinox in the Northern Hemisphere.
(though many people disagree with this
and rather follow different calendars
that are considered canon in their specific religion)
Easter is considered to be a religious holiday in some Abrahamic religions.
Because of the dates being in spring and the assimilation of other religions, Easter merged with other traditional Spring Festivals.
Hence the bunnies and the eggs which are fertility symbols in several other religions.
