The Advent wreath is a Christian tradition that marks the four weeks leading up to Christmas. It is a circular wreath made of evergreen branches with four candles, sometimes with a fifth white candle in the center. The wreath is lit on each of the four Sundays of Advent, with an additional candle being lit on each subsequent Sunday until all four candles are lit. The wreath is often accompanied by Bible readings, devotions, and prayers. The custom originated in family settings, but has also become common in public worship.
