Yeah, your first comment made it sound to me like the country shuts down (grocery stores, home improvement stores, furnite stores, banks, offices, government agencies, taxis, ...) ;-)

I found one Austrian source ( https://www.vol.at/wo-die-produktion-urlaub-macht/3314076 ) mentioning the issue and I can see how it would make sense for some industries to need some maintenance time each year.
