The liturgical year is a calendar used by many Christian denominations to organize the annual cycle of religious events and celebrations. It is divided into different seasons, each with its own themes and observances, such as Advent, Christmas, Lent, and Easter. These seasons help guide the worship and spiritual practices of the community throughout the year. Each season of the liturgical year has specific readings, prayers, and rituals that reflect the life of Jesus Christ and the teachings of the Christian faith. The year begins with Advent, a time of preparation for the celebration of Christmas, and culminates with Pentecost, which commemorates the descent of the Holy Spirit upon the apostles.
