Easter is the most important annual religious feast in the Christian liturgical year. According to Christian scripture, Jesus was resurrected from the dead on the third day after his crucifixion.
Some Christians celebrate this resurrection on Easter Day or Easter Sunday (also Resurrection Day or Resurrection Sunday), two days after Good Friday and three days after Maundy Thursday. Easter also refers to the season of the church year called Eastertide or the Easter Season. Traditionally the Easter Season lasted for the forty days from Easter Day until Ascension Day but now officially lasts for the fifty days until Pentecost. The first week of the Easter Season is known as Easter Week or the Octave of Easter. Easter also marks the end of Lent, a season of fasting, prayer, and penance.
As with many other Christian dates, the celebration of Easter extends beyond the church. Since its origins, it has been a time of celebration and feasting and many Traditional Easter games and customs developed, such as Egg rolling, Egg tapping, Pace egging and Egg decorating. Today Easter is commercially important, seeing wide sales of greeting cards and confectionery such as chocolate Easter eggs, marshmallow bunnies, Peeps, and jelly beans. Even many non-Christians celebrate these aspects of the holiday while eschewing the religious aspects. (From: Wikipedia, license: CCA-SA)
