In the Christian religion Easter is celebrated to remember when Christ rose from the dead after 3 days in a tomb.
It also stems from the Greek celebration of the beginning of spring celebrating the return of their goddess Eostre, goddess of spring, after the cold winter.
The time of these celebrations often coincide and their traditions and symbols have somewhat intermixed.
Modern traditional symbols include the Easter bunny, Easter eggs, and chicks.
In both Christian and pagan religions the holiday is used to celebrate new life and rebirth.
