New Year's Day on 1 January is an occasion for further secular festivities or for rest from the celebrations of the night before. In the Roman Rite of the Roman Catholic Church, it is the Solemnity of Mary, Mother of God, liturgically celebrated on the Octave Day of Christmas. It has also been celebrated, and still is in some denominations, as the Feast of the Circumcision of Christ, because according to Jewish tradition He would have been circumcised on the eighth day after His Birth, inclusively counting the first day and last day. This day, or some day proximate to it, is also celebrated by the Roman Catholics as World Day of Peace.
