Streichtag is a German term for special punishment days, a concept that was introduced in some European convent schools. The term Streich- is related to the English word "strike" and is in this context an antiquated German term for the strokes (cuts) of corporal punishment. "-Tag" means "day".
There seem to have been two concepts behind the idea of the Streichtag:
- Either, for each individual student was recorded a list of actual punishable offenses committed. These were summed up in lists and the resulting "bill" was settled on the Streichtag.
- And/Or, on that special day, every student was punished, guilty or not. This was a kind of maintenance spanking -- to keep the students "in line" and to punish any unknown misdeeds that had escaped the attention of the schoolmasters.
A true story is recorded of a dramatic event that happened in the convent school of St. Gallen in Switzerland. When a Streichtag came and the dreaded mass-punishments were to take place, a boy was sent to go and fetch the birch rods. Out of terror he pulled a burning piece of wood from the fireplace and put the roof on fire, shouting for help. The flames consumed several of the convent's buildings before they were put out.
