Easter eggs, also called Paschal eggs, and Egg of Easter are eggs that are sometimes decorated. They are usually used as gifts on the occasion of Easter. As such, Easter eggs are common during the season of Eastertide. The oldest tradition is to use dyed and painted chicken eggs, but a modern custom is to substitute chocolate eggs wrapped in coloured foil, hand-carved wooden eggs, or plastic eggs filled with confectionery such as chocolate. However, real eggs continue to be used in Central and Eastern European tradition.
