About Ratio

The traditional Roman calendar, according to the rubrics of 1960 and the Missal of 1962, with the holy days of obligation and the days of fast and abstinence of the United States.

The calendar, the Mass texts in Latin and English, and Lauds of the Little Office of Our Lady come from the Divinum Officium project (MIT licence). Its English translations are drawn from the Tridentine Latin Rite Missal Project, the propers of Fr. Brian Austin, FSSP, and The Catholic Missal (1943). Where it differs, the calendar of your diocese or chapel prevails.

Years built: 2026 and 2027.
