Ostara
Easter gets its name from the Teutonic goddess of spring and the dawn, whose name is spelled Oestre or Eastre (the origin of the word "east" comes from various Germanic, Austro-Hungarian words for dawn that share the root for the word "aurora" which means " to shine"). Modern pagans have generally accepted the spelling "Ostara" which honors this goddess as our word for the Vernal Equinox. The 1974 edition of Webster's New World Dictionary defines Easter thus: "orig., name of pagan vernal festival almost coincident in date with paschal festival of the church; Eastre, dawn goddess; 1. An annual Christian festival celebrating the resurrection of Jesus, held on the first Sunday after the date of the first full moon that occurs on or after March 21." The Vernal Equinox usually falls somewhere between March 19th and 22nd (note that the dictionary only mentions March 21st, as opposed to the date of the actual Equinox), and depending upon when the first full moon on or after the Equinox occurs, Easter falls sometime between late-March and mid-April.
Because the Equinox and Easter are so close, many Catholics and others who celebrate Easter often see this holiday (which observes Christ's resurrection from the dead after his death on Good Friday) as being synonymous with rebirth and rejuvenation: the symbolic resurrection of Christ is echoed in the awakening of the plant and animal life around us. But if we look more closely at some of these Easter customs, we will see that the origins are surprisingly, well, pagan! Eggs, bunnies, candy, Easter baskets, new clothes, all these "traditions" have their origin in practices which may have little or nothing to do with the Christian holiday.
