The Liturgical Calendar is no ordinary calendar and its purpose is not to simply mark the passage of time, but to celebrate and understand more fully the entire revelation of Jesus Christ. From his incarnation and birth until the day of Pentecost, and the expectation of his return in glory, we enter into the paschal mystery – the passion, death, resurrection and ascension of Jesus.
The Liturgical Year is marked by special seasons – Advent, Christmas, Lent, the Triduum, Easter, and Ordinary Time. It begins on the first Sunday of Advent and ends on the feast of Christ the King. The calendar tells us what readings the Church has designated to be used for each day and it names the special feasts and commemorations celebrated during each season. It even indicates the color of the vestments to be worn by the priest during each celebration of the liturgy.
The Liturgical Calendar is often depicted as a circle where each spoke in this calendar wheel represents a week and each period of liturgical time is a different color.
