Today is the first of four Sundays leading up to Christmas which in Germany are celebrated as part of Advent. Traditionally, each family decorates a wreath of fir or spruce branches with ornaments much like those hung on the Christmas tree as well as four thick candles. This wreath is known as the Adventskranz or "Advent wreath", and on the first Advent Sunday one of the candles is lit, on the second two, and so on, until all four are burning by the time Christmas arrives.

I think this tradition helps to make the joyful anticipation for Christmas even greater. If you want to see the Adventskranz my mom created last year, you can see that post here. Happy holidays everyone!
