The Catholic Liturgical Calendar is a system that organizes the annual cycle of the Church's celebrations and observances. It includes important seasons such as Advent, Christmas, Lent, and Easter, each with its own themes and rituals. The calendar helps the faithful to commemorate significant events in the life of Jesus Christ and the Saints. Each season is marked by specific colors, readings, and prayers that guide worship and reflection. The calendar also includes feast days dedicated to various Saints and important events in the Church's history, providing a rhythm to the spiritual life of the Catholic community throughout the year.
