Liturgical year

The liturgical year, also called the church year, Christian year, ecclesiastical calendar, or kalendar, consists of the cycle of liturgical days and seasons that determines when feast days, including celebrations of saints, are to be observed, and which portions of scripture are to be read.

Distinct liturgical colours may be used in connection with different seasons of the liturgical year. The dates of the festivals vary somewhat among the different churches, although the sequence and logic is largely the same.
