The Novena consists of five decades of the Rosary each day for twenty-seven days in petition; then immediately five decades each day for an additional twenty-seven days in thanksgiving, whether or not the request has been granted.
The meditations vary from day to day. On the first day meditate on the Joyful Mysteries; on the second day the Luminous Mysteries; on the third day the Sorrowful Mysteries; on the fourth day the Glorious Mysteries. On the fifth day, meditate again on the Joyful Mysteries; and so on throughout the first twenty-seven days.
After the first twenty-seven days, begin the circle again with the Joyful Mysteries.
THANKSGIVING: It does not matter if your petition has not been granted within the first 27 days, proceed to the Thanksgiving cycle anyway.
Say your rosary the way you normally say the rosary, with any additional prayers or meditations you like you do. Just add the Petition and Thanksgiving prayers.
