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.

If you weren't used to regular calendars you wouldn't know that "August 10" means "about the middle of winter" either

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.

I find week numbers very cumbersome to use. Most calendars don't have them by default and most everyday interactions around dates don't involve them. As a result it's a burdensome and unroutined lookup in some arbitrary calendar somewhere just to figure out ballpark distances from current moment. I much prefer date ranges.

It is a communicative convention. If you're the only person following a convention, it isn't. At least this is an additive one - unlike imperial/metric, it isn't a unit replacement. Even if you like "better" measures, you may want to stick with local ones. Little story - I noodle around with metalwork, and have some machinery. Because I lived in Europe for a bit, I am comfortable with metric, and metric mental math i…

It might be a mistake in the US, but of course machine shops outside the US are all metric - conversely, operating an imperial machine shop might be quite annoying outside the US.

Interestingly the US industry didn't switch to metric citing "conversion cost" (in the late 19th / early 20th century). Instead we continue to waste billions every year since: keeping double stock, projects failing (see: space), US engineers struggling with the system everyone else uses (and vice versa, though to a lesser extent, since US-made components and machinery are relatively irrelevant in industry) etc.

Presumably because then you know that the majority of week 1 is in the new year.

Yes exactly. Week 1 is the first week where the majority of the days in the week are in the new year. If Thursday is in the new year, so is also Friday, Saturday and Sunday and with those four days in the new year, it is always the majority of the week.

> If Thursday is in the new year, so is also Friday, Saturday and Sunday and with those four days in the new year, it is always the majority of the week.

That's only if you count Sunday as the last day of a week, instead of it being the first day of the following week.

August 10 is actually the middle of summer oO

EDIT: you are all lying, if christmas movies have taught me anything it is snowing everywhere in the world in december.

Here in Sweden, every calendar includes week numbers. You can enable viewing them in Outlook (I guess both ISO weeks and US style week numbering). Due to some school holidays always falling on the same week (Winter holiday on week 9 in Stockholm, for example), they have impact outside workplaces.

Schools of course find planning the year in weeks very convenient. This bleeds over into holiday planning at workplaces.

ISO counts Monday as the first day of the week.

I live in Canada, we use metric, I had to learn imperial when I started at a machine shop. The machines all worked to .0001 inches and we measured our pieces to 1/16" accuracy. Personally, despite using metric all my life and using it for almost everything else i've done. Using imperial and fractions of inches for that kind of work was more intuitive for me and a lot easier to figure out in my head. I find it a lot easier to mentally add fractions than decimals.

Most calendars in the US sold for "business" use show week numbers on each Sunday since week numbers are often used by people in payroll and finance. So it's not too hard to get a calendar that shows them and I also find it useful for things like working out 2/3 week sprints into the future.
