As far as I know Good Friday and Easter has always been Christian holidays, but has only recently has Easter been commercialized with the Easter bunny.
Look up Easter on Wikipedia
I took your advice...
The name of the Easter holiday comes from the pagan Germanic goddess Ēostre or Ostara, the goddess of fertility.
The original name for Easter and Passover are the same word in many languages, Pascha, and Passover is closely linked with Easter symbolically. So, it was probably more specifically a Jewish holiday long before it ever became a Christian holiday, according to Wikipedia.
The first mention of the Easter Bunny (Hare) and Easter Eggs was in 1682, when it was a German tradition. It is first known to be practiced as a custom in America in the 1700s.
It's certainly no coincidence that rabbits and eggs, symbols of fertility common with the pagan celebration of the life giving spring, are celebrated along with Easter. People have been celebrating fertility around the March Equinox for millennia.
