ISO8601 is YYYY-MM-DD nothing to do with weeks and isn;t the only difference of RFC3339 that you can use a space instead of a T in between the date and time?
Also RFC3339 is only an internet standard while ISO is a generally international standard?
Yeah I know, but it also has a different use case. As far as I know RFC3339 is mostly used for programming while ISO8601 is the standard for international communication and I wish people would use it more. I have processed American invoices in the wrong month because of their date structure.
I have no reason to it, but I always write my date ISO 8601 (YYYY-MM-DD)
No idea what you based those claims on, but the spec itself (I have the pdf) and Wikipedia’s summary disagree. ISO8601 allows for YYY-MM-DD yes but it allows for a bunch of silly stuff.
The omitting of timezones doesn’t matter to a vast majority of the world, since most countries only have one time zone so I don’t see a reason why that is relevant in most use cases.
ISO is a general standard, it’s in the name and the RFC is created for the internet, that is also in the name/description of the RF.
Using 2025-164 can be handy, I actually use the day of the year to check what invoices from previous year are open since those are the invoices that are due 164 days or more.

ISO8601 is much much looser than RFC3339:

Both “2025-W24-4” and “2025‐163” are valid representations of today’s date in ISO8601.
(Also the optional timezone makes it utterly useless.)
