On these pages, you can find the rubrics for each hour for each of the five (5) ranks of office, to wit; the Sunday office, the festive office (1st Class Feasts), the semi-festive office (2nd Class Feasts), the ordinary office (3rd Class Feasts), and the ferial office (4th Class).
These are excerpted from the Rubrics found in the 1967 English translation, supplemented with the rubrics for Prime and Pretiosa from the 1962 Latin edition.
