The Easter holiday sometimes occurs in March but this year it falls on April first, which is also known as April Fool Day.
Easter eggs (also called Paschal eggs) are decorated eggs often used as gifts or decorations on the occasion of Easter or more generally as part of a springtime celebration. Though Easter eggs are common during the season of Eastertide, the egg being symbolic of spring is much older than the religious holiday.
Dyed and painted chicken eggs are the oldest traditional form and are still done today, but they compete with the commercial chocolate eggs wrapped in colored foil and the plastic eggs that people fill with candy, coins, lottery tickets and small gifts.
As a symbol of fertility and rebirth, Christianity adopted them as part of the celebration of Eastertide. I have read that the egg was sometimes said to symbolize the empty tomb from which Jesus resurrected, and that staining eggs red to represent the blood of Christ has been proposed. The custom of the Easter egg can be traced to early Christians of Mesopotamia, and from there it spread into Russia and Siberia through the Orthodox Churches, and later into Europe through the Catholic and Protestant Churches.
Easter eggs are sometimes called Paschal eggs as Easter can be called Pascha (Greek, Latin) or Resurrection Sunday.
A very different kind of “Easter egg” of a modern and technology-related sort is an intentional inside joke, hidden message, image or secret feature of a work. These Easter eggs are found in a computer programs, video games and sometimes in DVD menu screens. The term suggests the traditional Easter egg hunt with the hope of getting a prize when you are successful.
This usage was coined to describe a hidden message marketing device in the Atari video game “Adventure ” that led players on a hunt to find further hidden messages in later games.
In the novel Ready Player One, the plot involves several Easter eggs discovered in video games. The novel is now a Steven Spielberg film that opened yesterday.
