CCC 2185

On Sundays and other holy days of obligation, the faithful are to refrain from engaging in work or activities that hinder the worship owed to God, the joy proper to the Lord's Day, the performance of the works of mercy, and the appropriate relaxation of mind and body. Family needs or important social service can legitimately excuse from the obligation of Sunday rest. the faithful should see to it that legitimate excuses do not lead to habits prejudicial to religion, family life, and health. The charity of truth seeks holy leisure - the necessity of charity accepts just work.
