This reminds me of the time when I removed en-US from windows, leaving just en-GB, and it blue screened.

It's both surprising and irritating how many US-centric things are just assumed. (Don't even get me started on paper sizes...! ;) )

The amount of times that darn keyboard selector appears for no reason in Windows because its once again added en-US as a language, which it then switches to randomly for seemingly no reason and all of a sudden my symbols are all in the wrong places. One day someone at Microsoft is going to look at that bug and fix it....

I discovered just this week that the numbering of weeks within the year is different between US and Europe, thus, cal -w can show different numbers for some years depending on the locale. Outlook can probably also show different things depending on the system settings.

Europe uses the algo according to the ISO 8601 standard, where the week no.1 is the one with January 1st occuring between Monday and Thursday, inclusive. If the 1st happens on Friday or later within a week, it's considered a week no.52 or 53 of the previous year.

US does not use this scheme and [EDITED] I am not sure what method is applied there.

Some companies use week numbers in business talks, planning and scheduling, so be aware who is speaking about which weeks!

Even the concept "within that week" depends on whether you consider the week to begin on Monday or Sunday. (or elsewhere I suppose)

[kunley]

Yes but for the purpose of mentioned ISO 8601, the start of the week is assumed to be Monday.

As someone that changes the default as well, yep a pain.
