Easter or Resurrection Sunday is a religious festivity and a holiday that celebrates the resurrection of Jesus three days after his crucifixion on Calvary, according to the New Testament account. It is the main celebration of the Christian liturgical year and also the oldest and most important Christian feast. The Easter date determines all other dates of Christian mobile feasts, except those related to Advent. Easter Sunday marks the culmination of the Passion of Christ and is preceded by Lent, a forty-day period of fasting, prayers, and penances.
The term “Easter” derives, through the Latin Pascha and the Biblical Greek Πάσχα Paskha, from Hebrew (Pesaḥ or Pesach), the Jewish Passover
The last week of Lent is called Holy Week, which contains the so-called Easter Triduum, including Holy Thursday, which commemorates the Last Supper and the Lava foot ceremony that preceded it and also Good Friday, which recalls the crucifixion and death of Jesus Easter is followed by a fifty-day period called Easter Season that extends to Pentecost Sunday.
Easter is a mobile party, which means your date is not fixed in relation to the calendar. The First Council of Nicea (325) established the date of Easter as the first Sunday after the full moon after the beginning of the vernal equinox (the so-called Full Moon Pascal). From an ecclesiastical point of view, the vernal equinox takes place on March 21 (even though it occurs on March 20 in most years from an astronomical point of view) and the “full moon” does not necessarily occur on the correct astronomical date. Therefore, the Easter date varies between March 22 and April 25 (inclusive). Eastern Christians base their calculations on the Julian calendar, whose date from March 21 corresponds in the 21st century to April 3 in the Gregorian calendar used in the West. Therefore, Easter in the east varies between April 4 and 8 May inclusive.
Christian Easter is linked to Jewish Easter by date and also by many of its central symbolisms. Unlike English, which has two distinct words for the two parties (Easter and Passover respectively), in Portuguese and in many other languages the two are called by the same name or very similar names. Pascal customs vary widely among Christians all over the world and include morning masses, the exchange of Easter greeting and Easter eggs, which were originally a symbol of the empty tomb. Many other customs have come to be associated with Easter and are observed by Christians and non-Christians, such as egg hunting, easter bunny and Easter Parade. There are also a large number of typical dishes connected to Pascoa and ranging from region to region.
