St. Andrew's Novena
St. Andrew's Novena is a prayer that is recited fifteen times a day, starting on the Feast of St. Andrew November 30, until Christmas. I know a novena is for nine days, but this one is for 25 days. The prayer is very short, so it's not a hardship.
As Catholics, we know we're praying to God, not St. Andrew. It's called St. Andrew's Novena because it starts on the Feast of St. Andrew, that's why.
It's a good way to focus on Christmas,because of the meaning of the prayer:
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 piercing cold. In that hour, vouchsafe, O my God! to hear my prayer and grant my desires, through the merits of Our Saviour Jesus Christ, and of His Blessed Mother. Amen.
