Lent is the 40 days before Easter and Advent is the 4 Sundays before Christmas.

The Glorious Mysteries are prayed on a Wednesdays and most Sundays. The exception are the Sundays of Lent, on which the Sorrowful Mysteries are prayed and the Sundays of Advent, on which the Joyful Mysteries are prayed.
