In the Prayer of the Church, prayed through the hours of each day by many Christians, and which priests and many Religious communities pray on behalf of all people, the journey of Advent moves up a gear on December 17 when the date appears alongside the day of the week in the Breviary. This marks the last week of preparation for Christmas, with each of these seven days marked with one of the “O antiphons”

Fr. Z’s blog gives a helpful introduction and a links if you wish to pray with these antiphons over the next week.
