The Advent wreath, or Advent crown, is a Christian tradition that symbolizes the passage of the four weeks of Advent in the liturgical calendar of the Western church. The Advent Wreath is traditionally a Lutheran practice, albeit it has spread to many other Christian denominations.
It is usually a horizontal evergreen wreath with four candles and often, a fifth, white candle in the center. Beginning with the First Sunday of Advent, the lighting of a candle can be accompanied by a Bible reading and prayers. An additional candle is lit during each subsequent week until, by the last Sunday before Christmas, all four candles are lit. Some Advent wreaths include a fifth, "Christ" candle which can be lit at Christmas. The custom is observed both in family settings and at public church services.
