I started using 8601 without even thinking about it for one simple reason. Alphabetical sorting just works with YYYYmmdd

So for example, log20220804.txt

At the very least, use four digit years, not 22 for 2022.

I've been using that format too for the same reason, without knowing about 8601. Day/Month/Year is great for a person (I'm in Aus) since we, as human beings, intrinsically know what year it is, and probably know what month it is if we haven't been on a bender. But string sorting is so much easier using yyyyMMdd format.

yyyymmdd is incorrect, as pointed out explicitly in the xkcd you linked.

The format is yyyy-mm-dd.
