What is Easter?
Easter is the most important holiday of the Christian year, observed in March, April, or May each year to celebrate the resurrection of Jesus from the dead after his death by crucifixion (see Good Friday), which Christians believe happened at about this time of year around AD 30-33. (Easter can also refer to the season of the church year, lasting for fifty days, which follows this holiday and ends around Pentecost.
Easter, the Sunday of the Resurrection, Pascha, or Resurrection Day, is the most important religious feast of the Christian liturgical year, observed at some point between late March and late April each year (early April to early May in Eastern Christianity), following the cycle of the moon. It celebrates the resurrection of Jesus, which Christians believe occurred on the third day of his death by crucifixion some time in the period AD 27 to 33. Easter also refers to the season of the church year, called Eastertide or the Easter Season. Traditionally the Easter Season lasted for the forty days from Easter Day until Ascension Day but now officially lasts for the fifty days until Pentecost. The first week of the Easter Season is known as Easter Week or the Octave of Easter.
In most languages of Christian societies, other than English, German and some Slavic languages, the holiday’s name is derived from Pesach, the Hebrew name of Passover, via the equivalent Greek name, Pascha. Easter 
depends on Passover not only for much of its symbolic meaning but also for its position in the calendar; the Last Supper shared by Jesus and his disciples before his crucifixion is generally thought of as a Passover meal, based on the chronology in the Gospels. Some, however, interpreting “Passover” in John 18:28 as a single meal and not a seven-day festival, interpret the Gospel of John as differing from the Synoptic Gospels by placing Christ’s death at the time of the slaughter of the Passover lambs, which would put the Last Supper slightly before Passover, on 14 Nisan of the Bible’s Hebrew calendar. According to the Catholic Encyclopedia, “In fact, the Jewish feast was taken over into the Christian Easter celebration.”
The English name, “Easter”, and the German, “Ostern”, derive from the name of a putative Anglo-Saxon Goddess of the Dawn (thus, of spring, as the dawn of the year) — called Ä’aster, Ä’astre, and Ä’ostre in various dialects of Old English and Ostara in German. In England, the annual festive time in her honor was in the “Month of Easter” or Ä’ostur-monath, equivalent to April/Aprilis. The Venerable Bede, an 8th Century English Christian monk wrote in Latin:
“Eostur-monath, qui nunc paschalis mensis interpretatur, quondam a dea illorum quae Eostre vocabatur et cui in illo festa celebrabant nomen habuit.”
Translates as: “Eostur-month, which is now interpreted as the paschal month, was formerly named after the goddess Eostre, and has given its name to the festival.”
The observance of any non-Jewish special holiday throughout the Christian year is believed by some to be an innovation postdating the Early Church. The ecclesiastical historian Socrates Scholasticus (b. 380) attributes the observance of Easter by the church to the perpetuation of local custom, “just as many other customs have been established,” stating that neither Jesus nor his Apostles enjoined the keeping of this or any other festival. However, when read in context, this is not a rejection or denigration of the celebration—which, given its currency in Scholasticus’ time would be surprising—but is merely part of a defense of the diverse methods for computing its date. Indeed, although he describes the details of the Easter celebration as deriving from local custom, he insists the feast itself is universally observed.
In Western Christianity, Easter always falls on a Sunday from March 22 to April 25 inclusive. The following day, Easter Monday, is a legal holiday in many countries with predominantly Christian traditions. In Eastern Christianity, Easter falls between April 4 and May 8 between 1900 and 1970 based on the Gregorian date.
Easter and the holidays that are related to it are moveable feasts, in that they do not fall on a fixed date in the Gregorian or Julian calendars (which follow the motion of the sun and the seasons). Instead, they are based on a lunar calendar similar to the Hebrew Calendar. The precise date of Easter has often been a matter for contention.
At the First Council of Nicaea in 325 it was decided that Easter would be celebrated on the same Sunday throughout the Church, but it is probable that no method was specified by the Council. (No contemporary account of the Council’s decisions has survived.) Instead, the matter seems to have been referred to the church of Alexandria, which city had the best reputation for scholarship at the time. The Catholic Epiphanius wrote in the mid-4th Century, “…the emperor…convened a council of 318 bishops…in the city of Nicea…They passed certain ecclesiastical canons at the council besides, and at the same time decreed in regard to the Passover that there must be one unanimous concord on the celebration of God’s holy and supremely excellent day. For it was variously observed by people…”
The practice of those following Alexandria was to celebrate Easter on the first Sunday after the earliest fourteenth day of a lunar month that occurred on or after March 21. While since the Middle Ages this practice has sometimes been more succinctly phrased as Easter is observed on the Sunday after the first full moon on or after the day of the vernal equinox, this does not reflect the actual ecclesiastical rules precisely. The reason for this is that the full moon involved (called the Paschal full moon) is not an astronomical full moon, but an ecclesiastical moon. Determined from tables, it coincides more or less with the astronomical full moon.
The ecclesiastical rules are:
* Easter falls on the first Sunday following the first ecclesiastical full moon that occurs on or after March 21 (the day of the ecclesiastical vernal equinox).
* This particular ecclesiastical full moon is the 14th day of a tabular lunation (new moon).
In applying the above rules, the Eastern Orthodox and Oriental Orthodox Churches calculate March 21 according to the Julian Calendar, whereas Western Christianity uses the Gregorian Calendar. An additional Orthodox rule, that Easter may neither precede nor coincide with the first day of the Jewish Passover, is unnecessary on two counts. It originally meant the 14th day of the moon (Nisan 14) in the Julian Easter tables, hence is included in the rule stated above. Some mistakenly think the rule applies to the modern Jewish Passover, whose rules were developed several centuries after the Orthodox Easter rules had already been written. Nevertheless, the drift of the modern Jewish Passover is not as great as the drift of the Julian Easter, so the use of the latter guarantees that it will always occur after the first day of the modern Jewish Passover.
The Church of Rome used its own methods to determine Easter until the 6th century, when it may have adopted the Alexandrian method as converted into the Julian calendar by Dionysius Exiguus (certain proof of this does not exist until the ninth century). Most churches in the British Isles used a late third century Roman method to determine Easter until they adopted the Alexandrian method at the Synod of Whitby in 664. Churches in western continental Europe used a late Roman method until the late 8th century during the reign of Charlemagne, when they finally adopted the Alexandrian method. Since western churches now use the Gregorian calendar to calculate the date and Eastern Orthodox churches use the original Julian calendar, their dates are not usually aligned in the present day.
The Easter festival is kept in many different ways among Western Christians. The traditional, liturgical observation of Easter, as practised among Roman Catholics and some Lutherans and Anglicans begins on the night of Holy Saturday with the Easter Vigil. This, the most important liturgy of the year, begins in total darkness with the blessing of the Easter fire, the lighting of the large Paschal candle (symbolic of the Risen Christ) and the chanting of the Exsultet or Easter Proclamation attributed to Saint Ambrose of Milan. After this service of light, a number of readings from the Old Testament are read; these tell the stories of creation, the sacrifice of Isaac, the crossing of the Red Sea, and the foretold coming of the Messiah. This part of the service climaxes with the singing of the Gloria and the Alleluia and the proclamation of the Gospel of the resurrection. A sermon may be preached after the gospel. Then the focus moves from the lectern to the font. Anciently, Easter was considered the most perfect time to receive baptism, and this practice is alive in Roman Catholicism, as it is the time when new members are initiated into the Church, and it is being revived in some other circles. Whether there are baptisms at this point or not, it is traditional for the congregation to renew the vows of their baptismal faith. This act is often sealed by the sprinkling of the congregation with holy water from the font. The Catholic sacrament of Confirmation is also celebrated at the Vigil. The Easter Vigil concludes with the celebration of the Eucharist (or ‘Holy Communion’). Certain variations in the Easter Vigil exist: Some churches read the Old Testament lessons before the procession of the Paschal candle, and then read the gospel immediately after the Exsultet. Some churches prefer to keep this vigil very early on the Sunday morning instead of the Saturday night, particularly Protestant churches, to reflect the gospel account of the women coming to the tomb at dawn on the first day of the week. These services are known as the Sunrise service and often occur in outdoor setting such as the church’s yard or a nearby park. The first recorded “Sunrise Service” took place in 1732 among the Single Brethren in the MoravianCongregation at Herrnhut, Saxony, in what is now Germany. Following an all-night vigil they went before dawn to the town graveyard, God’s Acre, on the hill above the town, to celebrate the Resurrection among the graves of the departed. This service was repeated the following year by the whole congregation and subsequently spread with the Moravian Missionaries around the world. The most famous “Moravian Sunrise Service” is in the Moravian Settlement Old Salem in Winston-Salem, North Carolina. The beautiful setting of the Graveyard, God’s Acre, the music of the Brass Choir numbering 500 pieces, and the simplicity of the service attract thousands of visitors each year and has earned for Winston-Salem the soubriquet “the Easter City.”
As with many other Christian dates, the celebration of Easter extends beyond the church. Since its origins, it has been a time of celebration and feasting. Today it is commercially important, seeing wide sales of greeting cards and confectionery such as chocolate Easter eggs, marshmallow bunnies, Peeps, and jelly beans.
Despite the religious preeminence of Easter, in many traditionally Christian countries Christmas is now a more prominent event in the calendar year, being unrivaled as a festive season, commercial opportunity, and time of family gathering — even for those of no or only nominal faith. Easter’s relatively modest secular observances place it a distant second or third among the less religiously inclined where Christmas is so prominent.
Some suggest an etymological relationship between Eostre and the Babylonian goddess Ishtar (variant spelling: Eshtar) and the possibility that aspects of an ancient festival accompanied the name, claiming that the worship of Bel and Astarte was anciently introduced into Britain, and that the hot cross buns of Good Friday and dyed eggs of Easter Sunday figured in the Chaldean rites just as they allegedly do now. These claims fail to account for a complete lack of any evidence of transmission from Mesopotamia through the rest of Europe to Britain. Instead, they posit a sudden appearance in the British Isles without any effects or records anywhere in the intervening continent. Such claims are more likely to be an example of a false etymology.
