This year’s observance notes
The civil year crosses two liturgical years. Transfers and precedence below follow the official annual U.S. calendar.
- The Annunciation is transferred from Holy Week to Monday, April 5.
- The Ascension is shown on Sunday, May 9, as observed in most U.S. dioceses. The ecclesiastical provinces of Boston, Hartford, New York, Omaha, and Philadelphia observe it on Thursday, May 6.
- Our Lady of Guadalupe is omitted because December 12 is the Third Sunday of Advent; the USCCB permits suitable Marian honor within the Sunday celebration.
Keep the Church’s calendar. Open a date for the principal observance, reading references, and permitted choices in the United States Roman Calendar.
Read with the saints. The daily readings draw from Montfort’s True Devotion and The Secret of the Rosary, and St. Alphonsus’s The Glories of Mary. Each passage links to its place in the complete book.
Honor Mary in the mysteries her saints contemplate.
St. Alphonsus gives discourses for Mary’s feasts, meditations on her sorrows, and prayers that lead the reader to her. Montfort directs those consecrated to Jesus through Mary to honor the Incarnation especially on March 25. Read their words, make their prayers your own, and keep the feasts with the Church.
- Receive the mystery.Attend the Church’s liturgy and hear the Word with Mary’s faith.
- Contemplate with her.Pray the Rosary mystery or Marian prayer that opens the feast more deeply.
- Become what you celebrate.Imitate her fiat, purity, charity, sorrow, confidence, and total belonging to Jesus.
