You enable week numbers in your computer's calendar.

interesting, this makes me think of Java that requires an IDE to be usable as a developer.

people have been using computers to make sense of the calendar since at least as far back as the Antikythera Mechanism. "you need a computer to figure it out" isn't a valid criticism of a date system, it's a tautology.

Most calendar systems are complicated because they have conflicting goals. You just can't divide the year into even, intuitive, useful segments and have it line up with one rotation of earth

A more traditional approach to the calendar might have January 1st on the same day of the week every year, with a variable period of holidays at the end of the year that aren't part of the normal week system. If we did things that way, the issue of "where should we start week 1?" couldn't even arise.

There are and have been calenders with intercalendar days, how does that make anything easier? Specifically, not every week would be a full week, which in itself is an exception because now a Monday could be followed by a Sunday.

I very explicitly didn't say this. Rather, I said that not every day would be part of a week.

If your locale supports them, then all calendars would contain them. I worked in many EU countries a couple of decades ago and they all had them in their print and work calendars and the software had it as well.

Tooling support is generally required to know what specific dates holidays are on as well, and we manage.

All this complexity because we have to adhere to some pope from 400 years ago. It's just sad.

What alternative do you propose?

Well, thank you for asking.

Here: https://en.wikipedia.org/wiki/International_Fixed_Calendar

As you can see, there are 13 months with 28 days and 1 day (on leap year this is 2 days). Now I'm a bit of a socialist in heart so that 1 day (or 2 on leap year) I would count as a month so we get 14 salaries. It's a win-win situation. Clean and simple.

That is a surprising amount of complexity, really makes you glad that ISO ironed out all the details, so when I recently told our development team composed of Swiss, German, Portuguese and Danish people that we would be going live in week 4 (of 2020), everyone understood just fine. I still find it strange that some countries have not adopted week numbers. Sure, you can say something like "the week of December 21st",…

That's a bad example. Knowing what week 4 is is easy ("End of January"). What's week 27? Or week 43? Without looking at a calendar I can only roughly guestimate.

Week numbers are easily compared to your present time. If you are in week 19, and you know you have to finish something by week 27, you can easily calculate how many weeks you have until that time.

I don’t need to know what exact dates week 27 is when reasoning about it, for most purposes, I can just do simple math to calculate how many weeks it is away.

how am I supposed to know when week 33 is?

If you’re planning at work, it’ll suffice to know that it’s 34 weeks away, more than half a year. If you work two-week sprints, you can easily calculate how many sprints you’ll have until them.

It’s not a replacement for dates, but a useful shorthand used when dealing with weeks.
