I’m definitely in the “for almost everything” camp. It’s less ambiguous especially when you consider the DD/MM vs MM/DD nonsense between US dates vs elsewhere. Pretty much the only time I don’t use ISO-8601 is when I’m using non-numeric month names like when saying a date out loud.
In Canada we use MM/DD and DD/MM so you never quite know which it is! There’s an expense spreadsheet I fill out for work that uses one format in one place and the other format in another…

I really wonder how americans were able to fuck this one up. There are three ways to arrange these and two of them are acceptable!
Edit: Yes, I meant common ways, not combinatorically possible ways.
Hmmm more like 6 ways but I get your point
Three ways that people actually use. YYYY-MM-DD, DD-MM-YYYY, and MM-DD-YYYY (ew).
AFAIK no-one does YYYY-DD-MM, DD-YYYY-MM, or MM-YYYY-DD… yet. Don’t let the Americans know about these formats, they might just start using them out of spite.
Nah man. Use 8601 for everything. They’re intrinsically chronologically sortable.

ISO-8601 over all other formats. 2023-08-09T21:11:00Z
Simple, sortable, intuitive.
Awful to actually read, though. Using T as a delimiter is mental… At least the hyphen provides some white space
