The faithful are required to attend Mass for the fourth Sunday of Advent, Dec. 24, and Christmas, Dec. 25.
To fulfill Sunday Mass, the faithful may attend the vigil Mass Dec. 23 or Sunday Mass Dec. 24, including Christmas Eve Mass. To fulfill the Christmas Mass obligation, the faithful may attend Christmas Eve or Christmas Day Mass. Christmas Eve Mass can count for Sunday or Christmas — but not both. The faithful must attend two separate Masses to fulfill their obligations.
A week later, the Solemnity of Mary is Jan. 1, but in 2024, it is not a holy day of obligation because it falls on a Monday.
