The Christian Calendar, also known as the Church Calendar, organizes the year around significant events in the life of Jesus Christ and the Christian faith. It includes seasons such as Advent, Christmas, Lent, Easter, and Pentecost, each with its own themes and observances. The calendar begins with Advent, a time of preparation for Christmas, which celebrates the birth of Jesus. Following Christmas, the calendar moves through the Lenten season, leading to Easter, which commemorates the resurrection of Jesus. The year concludes with Ordinary Time, a period of reflection and growth in faith.
