The Liturgical Calendar begins every year during the month of November on the First Sunday of Advent and runs through to the Solemnity of Christ the King.
The "Lectionary," the Mass readings from the Holy Bible, follows a Sunday cycle and a weekday cycle. The Liturgical Calendar follows a three-year cycle, each year being represented by the letters, A, B, and C. During the year A cycle, the Gospel of Matthew is the primary Gospel that is used for the readings. In year B, Mark is the primary Gospel. In year C, Luke is the primary Gospel. The Gospel of John is proclaimed on particular Sundays in each of the years.
