What mystery is recited every Saturday?

The mystery recited every Saturday in the Catholic tradition is the Joyful Mysteries of the Rosary. These mysteries focus on key events in the early life of Jesus and Mary, such as the Annunciation and the Nativity. While the Joyful Mysteries are typically prayed on Mondays and Thursdays, they can also be recited on Saturdays, especially during the Advent and Christmas seasons.
