My latest round of Luxembourg research has me stumbling across “7bre” and “8bre” a lot. At first glance, they made absolutely no sense. And then I realized that they’re actually a clever clerk’s shorthand.
For what? Figuring it out actually requires a little math.
7 written out is sept in French. Sept+ bre? Septembre – or September in English.
8bre is therefore October.
Knowing that should make your research a little easier!
