Take the Ordo for the traditional (1962) Missal and Breviary where ever you go without having to carry a book (or requiring a Wi-Fi/Internet connection after download). This digital version offers the same great info from our printed Ordo, but is completely mobile and always available on your smartphone!


Officially titled in Latin as Ordo Divini Officii Persolvendi Missaeque Sacrificii Peragendi (Pro Anno Domini 2021), the Ordo is an indispensable resource for clergy, sacristans, MCs and even the laity for properly following the daily rules of the traditional Roman Missal and Breviary.

The Ordo takes all of the various classification rules listed in the Rubricae Generales sections of the missal and breviary and applies them automatically to each liturgical day. So there's no need for you to look up the rubrics yourself!

Each daily entry includes the class of the day and its proper Mass, the color of the vestments, and lists the variable parts of the Mass and Breviary. [NB: the Ordo only provides the rules for setting up the missal and breviary; it does not include the prayers or readings of Mass.]


Other useful notes are also included, such as when a Requiem Mass is prohibited, special votive Mass options, and even pulpit announcements related to the liturgical year.

The Ordo app includes several appendices via a drop-down menu present on every entry page:

  • Explanation of abbreviations and signs

  • Excerpts of the Rubrics of the Roman Missal and Breviary

  • Concurrence/Occurrence table

  • Proper feasts for USA, Canada, Great Britain, Australia and New Zealand

Romanitas Press' Ordo is not only the most comprehensive edition available for the traditional Missal and Breviary, but also considered by many as the most accurate, year after year.

APPLE USERS: As of last year, Apple has refused to accept our Ordo app for publication, claiming that though it's an app, it does not fulfill their new criteria of an app! However, we hope to produce an Ebook edition for Apple users for 2021.
