The next day is appropriately a Saturday of the Dead (general commemoration of all faithful departed).The Eastern Orthodox Church uses a different method of calculating the date of Easter, so the Eastern Orthodox commemoration of Ascension will usually be after the western observance (either one week, or four weeks, or five weeks later; but occasionally on the same day).When celebrated on Sunday, the earliest possible date is May 3, and the latest is June 6.
The day before is the Apodosis (leave-taking) of Easter (i.e., the last day of the Feast of Easter).
Before the Vigil, the Paschal hours are said for the last time and the Paschal greeting is exchanged.
During the Polyeleos at Matins, the Epitaphios, which was placed on the altar on Holy Saturday (either at Matins or the Midnight Office, depending on local custom) is taken from the altar and carried in procession around the church. At the Divine Liturgy, special antiphons are sung in place of Psalms 102 and 145 and the Beatitudes.
The Epistle is Acts 1:1–12, and the Gospel is Luke –53.
Almighty God, whose blessed Son our Saviour Jesus Christ ascended far above all heavens, that he might fill all things: Mercifully give us faith to perceive that according to his promise he abideth with his Church on earth, even unto the end of the world; through the same thy Son Jesus Christ our Lord. The Roman Catholic Church in a number of countries that do not observe the feast as a public holiday has obtained permission from the Vatican to move observance of the Feast of the Ascension from the traditional Thursday to the following Sunday, the Sunday before Pentecost.
Similarly, The United Methodist Church allows the traditional celebration on Holy Thursday to be moved to Sunday.Representations of the mystery The Latin terms used for the feast, ascensio and, occasionally, ascensa, signify that Christ was raised up by his own powers, and it is from these terms that the holy day gets its name.In the Book of Common Prayer of the Anglican Communion, "Holy Thursday" is listed as another name for Ascension Day.The antiquarian Daniel Rock records the English custom of carrying at the head of the procession the banner bearing the device of the lion and at the foot the banner of the dragon, to symbolize the triumph of Christ in his ascension over the evil one (and can also be interpreted by analogy as the triumph of England over Wales).In some churches the scene of the Ascension was vividly reproduced by elevating the figure of Christ above the altar through an opening in the roof of the church.The earliest possible date for the feast is May 13 (of the western calendar), and the latest possible date is June 16.
