In your experience do bank holidays in France and Austria affect tourist sites and museums? Specifically, I'm looking at Whit Monday (6/6/2022 or 5/29/2023) in France and Feast of Corpus Christi (6/16/2022 or 6/15/2023) in Austria. My three planning stage itineraries all include France either in Paris or day trip to Chantilly and one itinerary includes Austria when we'd be in Salzburg.
As always, thanks for your help.
Edit: date of Whit Monday 2023 corrected.
