The practice is part of the First Fridays Devotion, which requires nine consecutive months of participation:
Attend Mass: Attend Mass on the first Friday of each month
Receive Communion: Receive Communion at Mass or another time on the first Friday of each month
Confession: Go to confession around the time of each Communion to fulfill the devotion
Pray: Pray for the intentions of the Holy Father
The Catholic Church grants a Plenary indulgence to those who complete the First Fridays Devotion. Some Catholic communities also encourage the practice of the Holy Hour the night before First Fridays or during the Exposition of the Blessed Sacrament on First Fridays.
