In 2023, the Solemnity of Mary, Mother of God, January 1, falls on a Sunday, and the Ascension of the Lord, May 21, is also on a Sunday. Catholics are obligated to attend Mass every Sunday, so we chose to include them on this list.

Christmas, December 25, 2023, will be on a Monday and will remain a Holy Day of Obligation for this year. There will be no dispensation for Christmas. Pay close attention to the local Mass schedule because the faithful will need to attend both the fourth Sunday of Advent Mass (a Vigil Mass after 4pm on Saturday, December 22, or morning Mass on Sunday, December 24) AND Christmas Mass (a Vigil on Sunday, December 24 after 4pm OR morning Mass on Sunday, December 25).
