The Liturgical Calendar is also known as the church year or Christian year, as well as the kalendar marked by Advent, Christmas, Lent, The Paschal Triduum or Three Days, Easter, and Ordinary Time. The Liturgical Calendar begins on the first Sunday of Advent, which usually occurs around the beginning of December or the end of November, and ends on the feast of Christ the King. Distinct liturgical colours may appear in connection with different seasons of the liturgical year.
