The Church Calendar is a system used by many Christian denominations to organize the year around significant events in the life of Jesus Christ and the history of the Church. It includes seasons such as Advent, Christmas, Lent, Easter, and Ordinary Time, each with its own themes and observances. Each season has specific days that commemorate important events, such as Holy Week, which includes Good Friday and Easter Sunday. The calendar helps guide worship, teaching, and personal reflection, allowing believers to engage with their faith throughout the year.
