Holy Days of Obligation are the most important feasts of the Liturgical Year besides Sunday, because of their centrality to our Catholic faith.

Catholic holy days of obligation are the days on which we’re expected to go to Mass. This list includes every single Sunday, along with a few additional days. Some feasts, such as Easter, are always celebrated on a Sunday, so they are always obligatory.
