lol, bear - this is what the church made out of the tradition. it started here:
''The first Adventskranz in Germany was done by Johann Hinrich Wichern (pictured right) in 1839 in front of the orphanage "Rough House." On a wooden hoop he attached 23 candles, four large white candles symbolizing the Sundays until Christmas Day, 19 small red candles, the weekdays until Christmas.
Every day the children lit a candle and on Christmas Eve all the candles were burning. Johann Hinrich Wichern used evergreen wreaths from the 1860''
and another one with not much better german

to recap:
''The candles used to be red during the Advent time, allegorical for the blood that Jesus Christ shed for humanity.
From Hamburg, the Advent wreath started its triumphal procession out to the Christian world: In 1925 an Advent wreath with four candles was set up in a catholic church in Cologne for the first time. Since 1930 as well in Munich''.
google translate is beyond hope but you get the drift, lol
