Christmas candles can be found on Advent wreaths or Christmas trees.
On Advent wreaths a candle is lit more on each of the four Advent Sundays, so that the weeks can be counted up to Christmas. This tradition first occurred in 1839 in northern Germany.
In addition to Christmas balls and Christmas candles decorate due Christmas trees in the Christmas period, the first Christmas trees were not lit. This tradition did not appear until the 17th century.
