The novena to Andrew, the Apostle, begins today, November 30th. It runs an unusual length, for 15 days, instead of the usual nine. It is prayed from the Feast of Saint Andrew until Christmas.
On the Get Fed website, they write about this novena thusly:
Prayer is an essential part of Advent. Reciting this special novena prayer each day is a simple yet beautiful way to celebrate the spiritual significance of the Advent season and to experience a deeper conversion to Jesus. The Saint Andrew Christmas novena is commonly found in many Advent prayer books which are also loaded with many other beautiful prayers and traditions for this time of year.
Saint Andrew Christmas Novena
Hail and blessed be the hour and moment in which the Son of God was born of the most pure Virgin Mary, at midnight, in Bethlehem, in the piercing cold. In that hour vouchsafe, I beseech thee, O my God, to hear my prayer and grant my desires through the merits of our Savior Jesus Christ, and of his blessed mother.
