As a service to the Church, the International Una Voce Federation (known by its Latin initials, FIUV) has taken up this task, with the help of Peter Day-Milne.
We are pleased to present, therefore, an Ordo for the calendar year 2023: to be exact, it runs from the First Sunday of Advent 2022 to the Octave of the Nativity of Our Lord, 1st January 2024.
Ordo Divini Officii recitandi sacrique peragendi secdundum antiquam Ritus Romani Formam, pro Anno Domini 2023.
This is the Ordo of the Universal Calendar: that is, without any of the feasts specific to particular parishes, dioceses, nations, or religious orders. These should be taken into account when using it: for example, the Patronal Feast of a parish church is a First Class feast in the parish, and the same is true of the primary Patron of a diocese, so these take precedence over many other feasts in that parish or diocese.
It is in Latin, following the conventions used by the old PCED Ordos.
Printed copies of the FIUV Ordo can be purchased from the
Latin Mass Society's online shop;
it can also be viewed online for free.
