I have some St. Andrew chaplets in my Etsy shop, and I am making more just now.
The Chaplet of St. Andrew is traditionally prayed during Advent, from the Feast of St. Andrew on November 30, until Christmas. The prayer is prayed fifteen times a day, and the fifteen beads help you keep track.
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.
