For Catholics, the liturgical calendar marks the Church year, a sequence of seasons and feasts celebrated in the liturgy during a year’s time. The liturgical calendar uses terms and measurements similar to a typical calendar. However, the liturgical calendar’s purpose is to celebrate and understand the mystery of Jesus Christ and the expectation of his return in glory. In each liturgical year, we celebrate the entire life and paschal mystery of Jesus Christ. Liturgies celebrated during different seasons have distinctive music and specific readings, prayers, rituals, and colors.
