Easter is observed around the world. It coincides with spring (at least in the northern hemisphere). The time of rebirth and renewal.
People celebrate in many different ways, both Christian and pre-Christian ways. There are a bunch of traditions. I did a little Googling to learn that the word Easter is reportedly derived from Eostre, the German goddess of spring and dawn. One of her symbols was a bunny which represented fertility, so having an Easter Bunny tradition makes sense.
I’m not sure what the leg represents. There wasn’t any mention of it in Wikipedia.
