Among the many customs of Christmas and Epiphany, this one is the announcement of the movable feasts between the Epiphany and the beginning of Advent.
After the reading of the Gospel, the traditional announcement of the movable holy days of the church year may be made in the following form: (These dates are correct for 2010.)
Dearly beloved brethren, you shall know that as we have rejoiced in the Birth of our Lord Jesus Christ, so there is announced to you by the mercy of God the joyous observance of the Resurrection of the same our Savior:
January 31st is Septuagesima Sunday.
On February 17th Ash Wednesday begins the most holy season of Lent.
On April 4th we shall celebrate with great rejoicing the holy Easter Festival of our Lord Jesus Christ.
May the 13th is the Feast of the Ascension of Our Lord Jesus Christ.
May the 23rd is the Feast of Pentecost.
November the 28th is the First Sunday in the Advent of Our Lord Jesus Christ, to Whom be honor and glory, world without end. Amen.
