Advent Christmas is a religious tradition observed by many Christians during the period leading up to Christmas. It typically spans four weeks and involves a series of devotional activities, such as lighting candles on an advent wreath, reading passages from the Bible, and reflecting on the meaning of Christmas. The advent period begins four Sundays before Christmas Day, and each Sunday represents a different aspect of the Christmas story. It's a time for preparing our hearts and minds for the celebration of Jesus' birth.
