In the Roman Rite, the Easter octave allows no other feasts to be celebrated or commemorated during it; a solemnity, such as the Annunciation, falling within it is transferred to the following Monday. If Easter Sunday or Easter Monday falls on 25 April, the Greater Litanies, which in the pre-1970 form of the Roman Rite are on that day, are transferred to the following Tuesday.[38]
By a decree of May 5, 2000, the Second Sunday of Easter (the Sunday after Easter Day itself), is known also in the Roman Rite as the Feast of the Divine Mercy.[39]
Ascension Thursday, which celebrates the return of Jesus to heaven following his resurrection, is the fortieth day of Easter, but, in places where it is not observed as a Holy Day of Obligation, the post-1969 form of the Roman rite transfers it to the following Sunday.[40]
Pentecost is the fiftieth and last day of the Easter season. It celebrates the sending of the Holy Spirit to the Apostles, which traditionally marks the birth of the Church, see also Apostolic Age.
Liturgical colour: white, but red on the feast of Pentecost.
This season, under various names, follows the Easter season and the feasts of Easter, Ascension, and Pentecost. In the post-1969 form of the Roman rite, Ordinary Time resumes on Pentecost Monday, omitting the Sunday which would have fallen on Pentecost. In the earlier form, where Pentecost is celebrated with an octave, the Time after Pentecost begins at Vespers on the Saturday after Pentecost. The Sundays resume their numbering at the point that will make the Sunday before Advent the thirty-fourth, omitting any weeks for which there is no room (present-day form of the Roman Rite) or are numbered as "Sundays after Pentecost" (pre-1970 Roman Rite, Eastern Orthodoxy and some Protestants) or as "Sundays after Trinity" (some Protestants). This season ends on the Saturday before the First Sunday of Advent.
