Christmas Trees, erection of, time of
Hereabouts (Rhineland) you put up your tree somewhere between the 4th Sunday of Advent and Cristmas Eve. The frequency distribution would be right shifted.
If you wanted festive cheer during the Advent, you had an Adventskranz with four candles. Each week you’d light one more. Had some Weihnachtsgebäck (Christmas cookies) and some songs.
As I see my timeline filling up with people setting up their trees, I start feeling old.
