The date of Easter, when the resurrection of Jesus is said to have taken place, changes from year to year. The reason for this variation is that Easter always falls on the first Sunday after the first full moon following the spring equinox.
Easter is quite similar to other major holidays like Christmas and Halloween, which have evolved over the last 200 years or so. In all of these holidays, Christian and non-Christian (pagan) elements have continued to blend together. Similar was the case with Easter, which falls in close proximity to another key point in the solar year: the vernal equinox (around March 20), when there are equal periods of light and darkness. For those in northern latitudes, the coming of spring is often met with excitement, as it means an end to the cold days of winter.
Spring also means the coming back to life of plants and trees that have been dormant for winter, as well as the birth of new life in the animal world. Given the symbolism of new life and rebirth, it was only natural to celebrate the resurrection of Jesus at this time of the year.
The naming of the celebration as “Easter” seems to go back to the name of a pre-Christian goddess in England, Eostre, who was celebrated at beginning of spring. The only reference to this goddess comes from the writings of the Venerable Bede, a British monk who lived in the late seventh and early eighth century. As religious studies scholar Bruce Forbes summarizes: “Bede wrote that the month in which English Christians were celebrating the resurrection of Jesus had been called Eosturmonath in Old English, referring to a goddess named Eostre. And even though Christians had begun affirming the Christian meaning of the celebration, they continued to use the name of the goddess to designate the season.”
Bede was so influential for later Christians that the name stuck, and hence Easter remains the name by which the English, Germans and Americans refer to the festival of Jesus’ resurrection.
