January 1 is the solemnity of Mary, Mother of God and is a holy day of obligation for Catholics. In addition to the obligation to attend Mass, 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.
