At midnight in the piercing cold....

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, [here mention your request] through the merits of Our Saviour Jesus Christ, and of His blessed Mother. Amen.
