The concept of Monday being the first day of the week isn't what surprises me. It was interesting to see the first day of the first week of 2019 is a date in 2018. EDIT: And I'm not in any way rendering judgment, merely uttering surprise. (The country that claims me as its citizen is irrelevant, and obviously we are indeed discussing ISO's definition of a "week". )

If weeks are to be considered as a unit that exists "in" a year, then there is no non-surprising solution to this notion of the first and last week of the year.

  Depends on your threshold of surprise. I would say that the end of a week going into the next year is much less surprising or even non-surprising.

    It's surprising that a day in 2019 is not part of a week in 2019.

      Out of context yes. In context the direction matters. If I say that 3am on Saturday is part of "Friday night", that's not very surprising. If I say that 10pm on Monday is part of "Tuesday morning", that's quite surprising.

> (The country that claims me as its citizen is irrelevant) The country is indeed irrelevant. The culture however is not: as I noted, this week ordinal definition is standard in europe, and the only people I've seen 1. not know about this definition of the week (and the concept of week-year) and 2. care enough to express any sort of surprise, have been american. > we are indeed discussing ISO's definition of a "week". The information in my comment was that this is the standard week in europe, any time somebody talks in weeks (which is common in many, many businesses, people'll tell you they'll do a job W23, or will ship your order W36), that's the one they're talking about.

I think there was some bug in a big service (Twitter? very unsure) a few years ago related to this conflict of ISO and 'real' year

Well, there are I think only two reasonable definitions. One leads to the first day of the week being in the previous year; the other to the first day of the first week being six days into the year. Each is independently 'surprising' in that it seems 'obviously wrong' without thinking about it.
