Hi, guys —


  • I was wondering why the Catholic Mass has to be celebrated before 12 o'clock on Sunday?
  • Was this decreed and, if so, by whom and when?

Thank you,

Mike replied:

Hi Peter,

To my knowledge it doesn't. We have a 5:30pm Mass on Sunday here in Natick, Massachusetts.

It may be diocesan regulated though I would think any Mass times would be regulated by the pastor of each parish.

The only Mass regulation I'm aware of for the United States is that all Saturday Vigil Masses for Sunday, cannot start before 4:00pm.

Hi, Peter —

I agree with Mike's answer.
