Happy Easter

Easter, annual festival commemorating the resurrection of Jesus Christ, and the principal feast of the Chris-tian year. It is celebrated on a Sunday on varying dates between March 22 and April 25 and is therefore called a movable feast. The dates of several other ecclesiastical festivals, extending over a period between Septuagesima Sunday (the ninth Sunday before Easter) and the first Sunday of Advent, are fixed in relation to the date of Easter.

Connected with the observance of Easter are the 40-day penitential season of Lent, beginning on Ash Wednesday and conclud-ing at midnight on Holy Saturday, the day before Easter Sunday; Holy Week, comon Palm Sunday, including Good Friday, the day of the crucifixion, and terwith Holy Saturday; and the Ocof Easter, extending from Easter Sun-day through the following Sunday. During the Octave of Easter in early Christian times, the newly baptized wore white garments, white being the liturgical color of Easter and signifying light, purity, and joy.

PRE-CHRISTIAN TRADITION

Easter, a Christian festival, embodies many pre-Christian traditions. The origin of its name is unknown. Scholars, how-ever, accepting the derivation proposed by the 8th-century English scholar St. Bede, believe it probably comes from Eastre, the Anglo-Saxon name of a Teutonic goddess of spring and fertility, to whom was dedi-cated a month corresponding to April. Her festival was celebrated on the day of the vernal equinox; traditions associated with the festival survive in the Easter rabbit, a symbol of fertility, and in colored easter eggs, originally painted with bright colors to represent the sunlight of spring, and used in Easter-egg rolling contests or given as gifts.

Such festivals, and the stories and legthat explain their origin, were comin ancient religions. A Greek leg-end tells of the return of Persephone, daughter of Demeter, goddess of the earth, from the underworld to the light of day; her return symbolized to the an Greeks the resurrection of life in the spring after the desolation of winter. Many ancient peoples shared similar legThe Phrygians believed that their omnipotent deity went to sleep at the time of the winter solstice, and they per-formed ceremonies with music and dancing at the spring equinox to awaken him. The Christian festival of Easter probably embodies a number of convergtraditions; most scholars emphasize the original relation of Easter to the Jew-ish festival of Passover, or Pesach, from which is derived Pasch, another name for Easter. The early Christians, many of whom were of Jewish origin, were brought up in the Hebrew tradition and regarded Easter as a new feature of the Passover festival, a commemoration of the advent of the Messiah as foretold by the prophets.

THE DATING OF EASTER

According to the New Testament, Christ was crucified on the eve of Passo-ver and shortly afterward rose from the dead. In consequence, the Easter festival commemorated Christ's resurrection. In time, a serious difference over the date of the Easter festival arose among Christians. Those of Jewish origin celebrated the res-urrection immediately following the Passofestival, which, according to their Babylonian lunar calendar, fell on the evening of the full moon (the 14th day in the month of Nisan, the first month of the year); by their reckoning, Easter, from year to year, fell on different days of the week.

Christians of Gentile origin, however, wished to commemorate the resurrection on the first day of the week, Sunday; by their method, Easter occurred on the same day of the week, but from year to year it fell on different dates.

An important historical result of the difference in reckoning the date of Easter was that the Christian churches in the East, which were closer to the birthplace of the new religion and in which old traditions were strong, observed Easter according to the date of the Passover festival. The churches of the West, descendants of Greco-Roman civilization, celebrated Easter on a Sunday.

RULINGS OF THE COUNCIL OF NICAEA ON THE DATE OF EASTER

Constantine the Great, Roman emconvoked the Council of Nicaea in 325. The council unanimously ruled that the Easter festival should be celebrated throughout the Christian world on the first Sunday after the full moon following the vernal equinox; and that if the full moon should occur on a Sunday and thereby coincide with the Passover festival, Easter should be commemorated on the Sunday following. Coincidence of the feasts of Easter and Passover was thus avoided.

The Council of Nicaea also decided that the calendar date of Easter was to be calculated at Alexandria, then the prin-cipal astronomical center of the world. The accurate determination of the date, however, proved an impossible task in view of the limited knowledge of the 4th-century world. The principal astronomiproblem involved was the discrep-ancy, called the epact, between the solar year and the lunar year. The chief calendric problem was a gradually indiscrepancy between the true t astronomical year and the Julian calendar then in
