Tridentine Calendar

The Tridentine Calendar is the calendar of saints to be honoured in the course of the liturgical year in the official liturgy of the Roman Rite as reformed by Pope Pius V, implementing a decision of the Council of Trent, which entrusted the task to the Pope.
The text of the Tridentine Calendar can be found in the original editions of the Tridentine Roman BreviaryBreviarium Romanum ex Decreto Sacrosancti Concilii Tridentini restitutum Apud Paulum Manutium, Roma 1568. Facsimile: Achille Maria Triacca, Breviarium Romanum. Editio princeps (1568), Libreria Editrice Vaticana, Città del Vaticano 1999 and of the Tridentine Roman Missal.Missale Romanum ex Decreto Sacrosancti Concilii Tridentini restitutum Pii V. Pont. Max. editum Apud haeredes Bartholomaei Faletti, Ioannem Varisei et socios, Roma 1570. Facsimile: Manlio Sodi, Antonio Maria Triacca, Missale Romanum. Editio princeps (1570), Libreria Editrice Vaticana, Città del Vaticano 1998, ISBN 88-209-2547-8.
Use of both these texts, which included Pius V's revised calendar, was made obligatory throughout the Latin Rite except where other texts of at least two centuries' antiquity were in use, and departures from it were not allowed. The Apostolic Constitution Quod a nobis, which imposed use of the Tridentine Roman Breviary, and the corresponding Apostolic Constitution Quo primum concerning the Tridentine Roman Missal both decreed: "No one whosoever is permitted to alter this letter or heedlessly to venture to go contrary to this notice of Our permission, statute, ordinance, command, precept, grant, indult, declaration, will, decree and prohibition. Should anyone, however, presume to commit such an act, he should know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul."Faith FactsIn Defense of the Pauline Mass
==Some of Pope Pius V's alterations of the existing Roman Calendar==
Pius V removed from the existing Roman calendar many mediaeval saints, keeping only about half a dozen who had been canonized after the eleventh century. His calendar did not include Saints Joachim, Anne, Anthony of Padua, Nicholas of Tolentino, Francis of Paola, Bernardino of Siena or Elizabeth of Hungary, nor any anatomical feasts, such as that of the Stigmata of Saint Francis of Assisi, or the Precious Blood or the Five Wounds of Christ. He removed the word "Immaculate" from the title of the 8 December feast of the Immaculate Conception of the Blessed Virgin Mary, abolished the previously existing special Mass for that day, whose Introit and Collect would be restored by Pope Pius IX, and directed that the Mass of the Nativity of Mary should be used instead, replacing the word "Nativity" with "Conception". He raised to the rank of double the feasts of the four Eastern Saints Athanasius of Alexandria, Basil of Caesarea, John Chrysostom and Gregory of Nazianzus, and, while he did not give them the title of Doctor of the Church, he assigned to them the common used for the four Western Doctors, Pope Gregory I, Augustine of Hippo, Jerome and Ambrose. On the other hand, he lowered the ranks of many saints' feasts, in order to allow celebration of Sundays and the ferias of Lent and Advent, which were outranked by most saints' feasts until the reform of Pope Pius X.Paul Cavendish, The Tridentine Mass
==Some differences in relation to later editions of the Roman calendar==
In the Tridentine Calendar, the rank of feasts is expressly indicated only if they are ranked as Double or Semidouble, while absence of an indication means that a feast is of the rank of Simple. (For the meaning of these terms see Ranking of liturgical days in the Roman Rite.) This tripartite ranking as Double, Semidouble, and Simple originated in the thirteenth century and, apart from deciding precedence in the case of two celebrations coinciding on the same day (as when a feast of the fixed calendar coincided with a Sunday, or with a feast or octave whose date depended on that of Easter), was of practical importance more for the Liturgy of the Hours than for the Mass.
Pope Clement VIII introduced the rank of Major Double when in 1604 he replaced the Missal of Pope Pius V with his own revision. This distinction and those of Double of the First Class and Double of the Second Class are absent in the Tridentine Calendar.
Editions of the Roman Calendar later than that of Pope Pius V show many cases of raising or lowering of the rank of individual feasts of saints, and of insertion of new celebrations into the calendar. The number of feasts in the Tridentine Calendar is much lower than that in later editions of the Roman Calendar, including the revision of 1970 that followed the Second Vatican Council.
To show the incremental crowding of the calendar, the Catholic Encyclopedia published the following table comparing the Roman Calendar as published in the Tridentine Roman Breviary of 1568 with the official revisions of 1662, 1631 and 1882, and with the situation in 1907.
Pope 	Date	Doubles, I Class	Doubles, II Class	Greater Doubles	Doubles	Semidoubles	Total
Pius V 	1568	19 	17 	0 	53 	60 	149
Clement VIII	1602	19 	18 	16 	43 	68 	164
Urban VIII 	1631	19 	18 	16 	45 	78 	176
Leo XIII 	1882	21 	18 	24 	128 	74 	275
- 	1907	23 	27 	25 	133 	72 	280
Soon after the publication of this 1907 table, Pope Pius X made a general revision of the rubrics of the calendar, the result of which (with a few additions by Pope Pius XI) can be seen in General Roman Calendar of 1954. This was followed by Pope Pius XII's simplifying revision of 1955 (see General Roman Calendar of Pope Pius XII). Pope John XXIII's General Roman Calendar of 1962, use of which is still authorized, with certain limitations for public use, by the motu proprio Summorum Pontificum, reduced the number of celebrations and completely abandoned the ranking as Doubles, Simples, etc. For the present-day form of the Roman-Rite liturgical calendar, see Roman Catholic calendar of saints.
