Canon 1247 is really quite clear:
On Sundays and other holy days of obligation, the faithful are obliged to participate in the Mass.
Moreover they are to abstain from those works and affairs which hinder the worship to be rendered to God, the joy proper to the Lord’s day, or the suitable relaxation of mind and body.

Do you want to go to hell?
