The Nine-Day Devotion is a Catholic tradition of prayer and devotion that takes place over nine consecutive days. It is also known as a Novena, which is derived from the Latin word for nine. The devotion typically involves praying the same set of prayers each day for nine days in a row, often with the intention of asking for a special favor or intercession. It is believed that the nine days of prayer will bring about a spiritual transformation and bring the petitioner closer to God.
