The Code of Canon Law provides the following general norm for the Latin Rite of the universal Church:
- Sunday is the day on which the paschal mystery is celebrated in light of the apostolic tradition and is to be observed as the foremost holy day of obligation in the universal Church. Also to be observed are the day of the Nativity of Our Lord Jesus Christ, the Epiphany, the Ascension and the Most Holy Body and Blood of Christ, Holy Mary Mother of God and her Immaculate Conception and Assumption, Saint Joseph, the Apostles Saints Peter and Paul, and finally, All Saints.
- However, the conference of bishops can abolish certain holy days of obligation or transfer them to a Sunday with prior approval of the Apostolic See.
Depending on one’s nation one could have more or fewer than the ten listed in the Code
