Liturgical Calendar

The liturgical year is the program's training structure. This calendar uses the 1962 (Old / Extraordinary Form) calendar as the structural primary; Novus Ordo dates are noted where they differ.

Each season has a character (interior or outward, penitential or joyful, foundational or mission) that shapes the week-to-week rhythm of training.

A note on movable dates

The liturgical year does not align cleanly with the civil calendar. Christmas is fixed at December 25, and saints' feast days are fixed dates, but Easter moves. It falls on the first Sunday after the first full moon on or after the spring equinox, anywhere between March 22 and April 25. Everything tied to Easter (Septuagesima, Lent, Passiontide, Eastertide, Rogation Days, Ascension, Pentecost, and the Whitsun Ember Days) shifts with it. A Lenten Ember Day in one year may fall in early February; the next year, in mid-March.

For exact dates in a given year, consult a published ordo (the FSSP and ICKSP both publish ordos for the 1962 calendar). The ranges below are the outer bounds.
