Didn't know where to but the 15th of August; L'Assomption and the feast day of the "invisible nation" - Louisiana, Canada? Doubtless other places as well. Big parties in Acadia north, and in Louisiana?
Bank holiday in France, too, and the symbolic end of the summer holiday season for many people now. Even though lots of people are still gone, things will start returning to normal, well not tomorrow because it is Friday but as of Monday the 19th.
