Fr. Kevin Drew, Catholic Exchange - Christmas isn’t just one day, but rather a season—a season that started with Evening Prayer on December 24th and ends on the feast of the Baptism, which was this last Sunday. Within that season there is an octave, from December 25th to January 1st, which mystically is the same day stretched out into eight. Since 1970, January 1st is a holy day of obligation for Mary, the Mother of God; for centuries before that, January 1st was the feast of the circumcision, as Christ was circumcised on the 8th day.
