I'm from Romania, and Monday is the first day of the week here.

When we hear that in other countries Sunday is considered the first day of the week, sounds almost as weird as being told that they consider "z" to be the first letter of the alphabet.

Also, it is very frustrating when a UI uses Sunday as the first day of the week, and I encounter that quite often.

I'm from Canada, and it's probably because of all the US calendars we tend to get, but I'm used to Sunday being the first day on the calendar while mentally, I consider Monday the first day of the week. So I plan things where "next week" means "after Sunday" but I'm used to seeing weekend days bordering the weekdays on a month-long calendar. I tend to think Sunday = 0 also. It's kind of like metric vs. imperial. Canadians never did fully switch over, e.g. for weight, height or indoor thermostats (for some folks).

"Weird" is in the eye of the beholder. As someone who grew up with Sunday always being considered the first day of the week, I find it weird to see places where day one is Monday.

tl;dr You're weird! No, you're weird!

Is it frustrating, though? I've seen it start on both days many times but it's never been frustrating, despite one being clearly different from what I've learned all my life.

Well, when I try to get something done in a calendar, having to do that remapping of the beginning and end of the weeks mentally... it gets in the way.
