For the traditional Roman Missal and Breviary
An Ordo is an indispensable resource for clergy, sacristans, masters of ceremonies and even the laity to properly follow the 1962 calendar of the traditional Roman Missal (Latin Mass) and Breviary (Divine Office).
​
Published annually, this 176-page book is officially entitled in Latin as Ordo Divini Officii Persolvendi Missaeque Sacrificii Peragendi Pro Anno Domini 2025 (The Order of the Divine Office Recited and of the Sacrifice of the Mass Celebrated for the Year of our Lord 2025).
​
As a reference guide, the Ordo applies the calendar rubrics of the missal and breviary in an easy-to-follow format for each liturgical day of the year, so you don't have to figure them out for yourself.
​
Offered since 1979, this printed Ordo is the first and longest-running traditional edition available in English. In addition to the typical entries found in ordos, this version uniquely features these useful items:
