My family and I went to the Christmas Eve late last night the 24th. It was great.
But do we have to go to Mass today the 25th as well?
I don’t think so. My family and I are probably going to go anyway because it feels weird not going Mass today, but I’m asking just in case we get surprised by a crazy blizzard and can’t go outside.
Yes, going to Mass yesterday counts as your Christmas obligation.
I think after 3 the day before counts as a Vigil.
Your Mass obligation has been met. You may choose to go to Christmas Day Mass as well, but it is by no means a requirement.
