Mhm. I find the list of minimum annual leave by country interesting. [0]

Seems like companies are not obliged to honor this holiday. Personally I think national holidays are probably having a positive impact, because it will give almost all folks an opportunity to rest, maybe do a small vacation, so they’ll come back and be more productive or have spent some savings to boost the economy.

Maybe it'll reduce the number of trading days in a year from 252 to 251. All the quants will need to update their models :)

It doesn't particularly. Federal employees are the only workers that are directly impacted.
