Easter is a mobile holiday. Unlike Christmas, which is nailed to the calendar, Easter is a moving target. In the West, Easter occurs on the Sunday after the first full moon following the Vernal Equinox (March 21, usually). So, an early Easter will be in the 20-somethings of March and a late one will be nearly the end of April. Churches in the East follow a different calendar, so Easter there is a week or two later.
In Christian churches, Easter celebrates the resurrection of Jesus three days after His crucifixion.
If that’s the case, where did we get egg-laying bunnies in the deal?
Well, that’s a little complicated.
Noah’s grandson, Nimrod, was a tyrant who founded lots of cities where people did crazy stuff. His wife, Semiramis, deified him after his death and declared her illegitimate son was actually Nimrod reborn to save mankind.
After being killed by a boar, Semiramis’ son was supposedly resurrected as plantlife by his mother’s tears.
The bunny and egg bit? Bunnies are prolific little critters, so they’re associated with fertility (something Semiramis is associated with), and there’s a fable about Semiramis hatching from an egg that fell from heaven into the Euphrates.
Like the modern versions of many Christian holidays, many of the traditions in this one go waaaaaay back to not-Christian roots.
