The modern English term Easter, cognate with modern Dutch ooster and German Ostern, developed from an Old English word that usually appears in the form Ēastrun, -on, or -an; but also as Ēastru, -o; and Ēastre or Ēostre.The most widely accepted theory of the origin of the term is that it is derived from the name of an Old English goddess mentioned by the 7th to 8th-century English monk Bede, who wrote that Ēosturmōnaþ (Old English 'Month of Ēostre', translated in Bede's time as "Paschal month") was an English month, corresponding to April, which he says "was once called after a goddess of theirs named Ēostre, in whose honour feasts were celebrated in that month".Eastern Christianity bases its calculations on the Julian Calendar.
By the Roman period, however, the sacrifices were performed in the mid-afternoon.Paul states, "Get rid of the old yeast that you may be a new batch without yeast—as you really are.For Christ, our Passover lamb, has been sacrificed"; One interpretation of the Gospel of John is that Jesus, as the Passover lamb, was crucified at roughly the same time as the Passover lambs were being slain in the temple, on the afternoon of Nisan 14.(See Resurrection of Jesus in Christian art.)Passover, of which it is regarded the Christian fulfillment; Septuagesima, Sexagesima, Quinquagesima, Shrove Tuesday, Ash Wednesday, Clean Monday, Lent, Great Lent, Palm Sunday, Holy Week, Maundy Thursday, Good Friday, and Holy Saturday which lead up to Easter; and Thomas Sunday, Ascension, Pentecost, Trinity Sunday, and Corpus Christi which follow it.is a festival and holiday celebrating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial after his crucifixion by the Romans at Calvary It is the culmination of the Passion of Jesus, preceded by Lent (or Great Lent), a forty-day period of fasting, prayer, and penance.Easter therefore varies between 4 April and 8 May in the Gregorian calendar (the Julian calendar is no longer used as the civil calendar of the countries where Eastern Christian traditions predominate).Also, because the Julian "full moon" is always several days after the astronomical full moon, the eastern Easter is often later, relative to the visible moon's phases, than western Easter.The First Council of Nicaea (325) established two rules, independence of the Jewish calendar and worldwide uniformity, which were the only rules for Easter explicitly laid down by the Council.(See also Computus and Reform of the date of Easter.) In particular, the Council did not decree that Easter must fall on Sunday. The following day, Easter Monday, is a legal holiday in many countries with predominantly Christian traditions.The ecclesiastical historian Socrates Scholasticus attributes the observance of Easter by the church to the perpetuation of its 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.Although he describes the details of the Easter celebration as deriving from local custom, he insists the feast itself is universally observed.
