Hell, the weird American "write it like you say it month dayeth of year" would be fine if they didn't use slashes. Sure it doesn't sort well but at least it wouldn't be ambiguous. Nobody would be confused if today was written 03-25/2023.
No, it doesn't. I mean, in certain contexts it can, but it doesn't exclusively in general, any more than it means “and/or” exclusively in general (though, it does mean “and/or” in “and/or” which probably isn’t something you should think about too much.)
It can just be a separator, as it is in American dates.
Fair point about and/or, but there's still a consistent pattern to that usage - also he/she, etc. I'm having trouble coming up with cases besides US dates where it isn't used to mean one of these two things:
"of": like one half (1/2) meaning one of two, or km/h meaning kilometers per hour, or page 14/55. In these contexts it means something within something else. In both cases there's the strong mathematical connotation of a numerator and a denominator.
"or": like in and/or or he/she.
The symbol has clear connotations, and the American date-format deviates from those.
