The octave day of Christmas has had a wide variety of commemorations attached to it throughout the Christian era. This work sought to trace the historical development of the feast, beginning with an ancient Marian feast from the Church at Rome. I explore some of the liturgical rites associated with this feast, and the subsequent development of the Feast of the Circumcision. I conclude the paper with a discussion of some of the more recent commemorations tied to the octave and then examine the current liturgical practices according to the Roman Missal.
