The format is similar to that of the Ordo published by the Priestly Fraternity of St. Peter for the Extraordinary Form of the Roman Rite. The calendar contains the entire liturgical year, according to the 1962 Breviarii Iuxta Ritum Ordinis Preædicatorum, updated with the most recent canonizations of Dominican saints.
In addition, the obituaries of the Masters General and the anniversaries of the Order are given, as well as the list of Dominican blesseds and the day of their votive office. Reminders are given for days when members of the Dominican Laity (formally called the "Third Ordo") can obtain indulgences during the year. As in the past the Office of Prime is also included.
Each day is annotated with the feast, the rank, commemorations (if any), and reminder notes, if the day includes an anniversary or the obit of a Master General of the Order. The list of obituaries of the Masters General has been updated to include the Masters who have died since the last Dominican Breviary was published in 1962.
