A couple of days late, but still relevant, is the Epiphany Proclamation, an ancient custom in which the dates  of Easter and other important moveable feasts were solemnly announced after the reading of the Gospel on the Feast of the Epiphany.

Dear brothers and sisters,

The glory of the Lord has shone upon us, and shall ever be manifest among us, until the day of his return.

Through the rhythms of times and seasons let us celebrate the mysteries of salvation. 

Let us recall the year's culmination, the Easter Triduum of the Lord:  his last supper, his crucifixion, his burial, and his rising celebrated between the evening of the seventeenth day of April and the evening of the nineteenth day of April, Easter Sunday being on the twentieth day of April.

Each Easter--as on each Sunday--the Holy Church makes present the great and saving death by which Christ has for ever conquered sin and death.  From Easter are reckoned all the days we keep holy.

Ash Wednesday, the beginning of Lent, will occur on the fifth day of March.

The Ascension of the Lord will be commemorated on the twenty-ninth day of May.

Pentecost, joyful conclusion of the season of Easter, will be celebrated on the eighth day of June.

And, this year the First Sunday of Advent will be on the thirtieth day of November.

Likewise the Pilgrim Church proclaims the passover of Christ in the feasts of the holy Mother of God, in the feasts of the Apostles and Saints, and in the commemoration of the faithful departed.

To Jesus Christ, who was, who is, and who is to come, Lord of time and history, be endless praise, for ever and ever.

Amen.
