When is Easter, Easter this year is Sunday April 8th.

Why is there an Easter?

Easter is the most important religious holiday of the Christian liturgical year, observed between late March and late April (early April to early May in Eastern Christianity) to celebrate the resurrection of Jesus, which Christians believe occurred after his death by crucifixion in AD 27-33 (see Good Friday). Easter can also refer to the season of the church year, lasting for fifty days, which follows this holiday and ends at Pentecost. Easter Day is also called the Sunday of the Resurrection.

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, a Jewish holiday to which the Christian Easter is intimately linked. 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 seder, based on the chronology in the Synoptic Gospels. The Gospel of John has a different chronology which has Christ's death at the time of the slaughter of the Passover lambs, which may have been for theological reasons but which is regarded by some scholars as more historically likely given the surrounding events. This would put the Last Supper slightly before Passover, on 14 Nisan of the Hebrew calendar. According to the Catholic Encyclopedia, "In fact, the Jewish feast was taken over into the Christian Easter celebration." The English and German names, "Easter" and "Ostern", are not etymologically derived from Pesach and are instead related to ancient names for the month of April, Eostremonat and Ostaramanoth respectively. According to the 8th century Christian monk and historian Bede, this month was dedicated to the pagan fertility goddess Eostre. The Easter Bunny is often identified as a remnant of this fertility festival, although there is no evidence of any link.

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 always falls between April 4 and May 8 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 calendar|Gregorian or Julian Calendar|Julian calendars (which follow the motion of the sun and the seasons). Instead, they are based on a lunar calendar similar—but not identical—to the Hebrew Calendar. The precise date of Easter has often been a matter for contention. At the First Council of Nicaea#Passover .28Easter.29 Controversy|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..."(Epiphanius. The Panarion of Epiphanius of Salamis, Books II and III (Sects 47-80), De Fide). Section VI, Verses 1,1 and 1,3. Translated by Frank Williams. EJ Brill, New York, 1994, pp.471-472). The practice of those following Rome 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 the day of the vernal equinox; * this particular ecclesiastical full moon is the 14th day of a tabular lunation (new moon); and * the vernal equinox is fixed as March 21.[http://aa.usno.navy.mil/faq/docs/easter.html] 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. At a summit in Aleppo, Syria, in 1997, the World Council of Churches proposed a reform in the calculation of Easter which would have replaced an equation-based method of calculating Easter with direct astronomical observation; this would have side-stepped the calendar issue and eliminated the difference in date between the Eastern and Western churches. The reform was proposed for implementation starting in 2001, but it was not ultimately adopted by any member body. {{further|Reform of the date of Easter}} A few clergymen of various denominations have advanced the notion of disregarding the moon altogether in determining the date of Easter; proposals include always observing the feast on the second Sunday in April, or always having seven Sundays between the Epiphany (feast)|Epiphany and Ash Wednesday, producing the same result except that in leap years Easter could fall on April 7. These suggestions have yet to attract significant support, and their adoption in the future is considered unlikely. ===Computations=== The calculations for the date of Easter are somewhat complicated. See computus for a discussion covering both the traditional tabular methods and more exclusively mathematical algorithms such as the one developed by mathematician Carl Friedrich Gauss. In the Western Church, Easter has not fallen on the earliest of the 35 possible dates, March 22, since 1818, and will not do so again until 2285. It will, however, fall on March 23, just one day after its earliest possible date in 2008. Easter last fell on the latest possible date, April 25 in 1943, and will next fall on that date in 2038. However, it will fall on April 24, just one day before this latest possible date in 2011. Historically, other forms of determining the holiday's date were also used. For example, Quartodecimanism was the practice of setting the holiday on the 14th day of the Hebrew Calendar|Jewish month of Nisan, which is the day of preparation for Passover. Western Christianity 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 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 and Holy Communion. Additional celebrations are usually offered on Easter Sunday itself. 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. In predominantly Roman Catholic Philippines, the morning of Easter (known in the national language as "Pasko ng Muling Pagkabuhay" or the Pasch of the Resurrection) is marked with joyous celebration, the first being the dawn "Salubong", wherein large statues of Jesus and Mary are brought together to meet, imagining the first reunion of Jesus and his mother Mary after Jesus' Resurrection. This is followed by the joyous Easter Mass. Some Christians wear their Sunday best to Church. This means a more formal dress and hats for some women. Eastern Christianity Easter is the fundamental and most important festival of the Eastern and Oriental Orthodox. Every other religious festival on their calendars, including Christmas, is secondary in importance to the celebration of the Resurrection of Jesus Christ. This is reflected in the cultures of countries that are traditionally Orthodox Christian majority. Easter-connected social customs are native and rich. Christmas customs, on the other hand, are usually foreign imports, either from Germany or the USA. Eastern Rite Catholics in communion with the Pope of Rome have similar emphasis in their calendars, and many of their liturgical customs are very similar. This is not to say that Christmas and other elements of the Christian liturgical calendar are ignored. Instead, these events are all seen as necessary but preliminary to the full climax of the Resurrection, in which all that has come before reaches fulfilment and fruition. Pascha (Easter) is the primary act that fulfils the purpose of Christ's ministry on earth—to defeat death by dying and to purify and exalt humanity by voluntarily assuming and overcoming human frailty. This is succinctly summarized by the Paschal Troparion, sung repeatedly during Pascha until the Apodosis of Pascha (which is the day before Ascension):
