Mysterii Paschalis is an apostolic letter issued motu proprio that is, "of his own accord" by Pope Paul VI on 14 February 1969. It reorganized the liturgical year of the Roman Rite and revised the liturgical celebrations of Jesus Christ and the saints in the General Roman Calendar.

Context

By this document, Pope Paul VI implemented the Second Vatican Council's norms for restoring the liturgical year and "approve[d] by Our apostolic authority…the new Roman Universal Calendar…and likewise the general norms concerning the arrangement of the liturgical year".

On 21 March of the same year the Congregation of Rites promulgated the revised norms on the liturgical year and the calendar by a decree signed by the Prefect Cardinal Benno Gut and the Secretary Ferdinando Giuseppe Antonelli. The motu proprio and the decree were included, with an unofficial commentary by the Council for the Proper implementation of the Constitution on the Sacred Liturgy, in the book Calendarium Romanum Libreria Editrice Vaticana, 1969.

The new norms became powerful on 1 January 1970.
