CHAPTER I : FEAST DAYS

Can. 1246 §1 The Lord's Day, on which the paschal mystery is celebrated, is by apostolic tradition to be observed in the universal Church as the primary holyday of obligation. In the same way the following holydays are to be observed: the Nativity of Our Lord Jesus Christ, the Epiphany, the Ascension of Christ, the feast of the Body and Blood of Christ, the feast of Mary the Mother of God, her Immaculate Conception, her Assumption, the feast of St Joseph, the feast of the Apostles SS Peter and Paul, and the feast of All Saints.

§2 However, the Episcopal Conference may, with the prior approval of the Apostolic See, suppress certain holydays of obligation or transfer them to a Sunday.

Can. 1247 On Sundays and other holydays of obligation, the faithful are obliged to assist at Mass. They are also to abstain from such work or business that would inhibit the worship to be given to God, the joy proper to the Lord's Day, or the due relaxation of mind and body.

Can. 1248 §1 The obligation of assisting at Mass is satisfied wherever Mass is celebrated in a catholic rite either on a holyday itself or on the evening of the previous day.

§2 If it is impossible to assist at a eucharistic celebration, either because no sacred minister is available or for some other grave reason, the faithful are strongly recommended to take part in a liturgy of the Word, if there be such in the parish church or some other sacred place, which is celebrated in accordance with the provisions laid down by the diocesan Bishop; or to spend an appropriate time in prayer, whether personally or as a family or, as occasion presents, in a group of families.
