Easter, which celebrates Jesus Christ's resurrection from the dead, is Christianity's most important holiday. It has been called a moveable feast because it doesn't fall on a set date every year, as most holidays do. Instead, Christian churches in the West celebrate Easter on the first Sunday following the full moon after the vernal equinox on March 21. Therefore, Easter is observed anywhere between March 22 and April 25 every year. Orthodox Christians use the Julian calendar to calculate when Easter will occur and typically celebrate the holiday a week or two after the Western churches, which follow the Gregorian calendar.
Easter is a religious holiday, but some of its customs, such as Easter eggs, are likely linked to pagan traditions. The egg, an ancient symbol of new life, has been associated with pagan festivals celebrating spring. From a Christian perspective, Easter eggs are said to represent Jesus' emergence from the tomb and resurrection. Decorating eggs for Easter is a tradition that dates back to at least the 13th century, according to some sources. One explanation for this custom is that eggs were formerly a forbidden food during the Lenten season, so people would paint and decorate them to mark the end of the period of penance and fasting, then eat them on Easter as a celebration.
Easter egg hunts and egg rolling are two popular egg-related traditions. In the U.S., the White House Easter Egg Roll, a race in which children push decorated, hard-boiled eggs across the White House lawn, is an annual event held the Monday after Easter. The first official White House egg roll occurred in 1878, when Rutherford B. Hayes was president. The event has no religious significance, although some people have considered egg rolling symbolic of the stone blocking Jesus' tomb being rolled away, leading to his resurrection.
