Mass Obligation

This year, Christmas falls on a Monday.

This year, Christmas falls on a Monday. Since Catholics are obliged to attend Mass on the Fourth
Sunday of Advent and again on Christmas, there are two obligations to fulfill.

These can be fulfilled in any of the following ways:

  • Saturday evening and Sunday evening;
  • Saturday evening and any time after midnight on Monday;
  • Sunday morning and Sunday evening;
  • Sunday morning and any time after midnight on Monday;
  • Sunday evening and any time after midnight on Monday.

In the last option, the Sunday obligation is fulfilled even if the Mass is for Christmas Eve.
