huh... somehow I didn't realize that. Crazy to look at the calendars. Still, the patron time is early Monday morning for Europe, public is Tuesday night.
It's not something I would stress about at all as it doesn't really matter. 2 days later is 2 days later no matter how you look at it. Imo saying that it's the next week (although technically true for me), is stretching it somewhat.
I am trying to find a list with the starting weekdays per country, but I can't really find something useful. I am intrigued now as I am not so sure anymore if it is as clearcut as I was thinking.
Edit:
https://en.wikipedia.org/wiki/Week#Week_numbering
There it says
Monday as first day: EU and most of other European countries, most of Asia and Oceania
Saturday as first day: Much of the Middle East
Sunday as first day: Canada, United States, India, Japan, Taiwan, Hong Kong, Macau, Israel, South Africa, most of Latin America
Again, it doesn't really matter imo, but I find things like this fascinating.
