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!

Do people outside of the US not say dates like “June first” etc? M/D/Y matches that. It’s really not weird at all, even if the international ambiguity is awful.

Yes it is objectively weird.

When you write down “07/01/1967” are you unaware that it is unclear whether you’re referring to July 1st or January 7th?

And despite the fact that you’re writing something down for the express purpose of communicating information, and you’re choosing to shorten it’s written format to save time and space, you’re ok with either

a) just leaving it ambiguous and communicating poorly

or

b) having to write extra words to give it context, taking up more space than just writing out “July 1st, 1967”?

At a fundamental user experience level, it is nonsensical to choose the American date format when your goals are 1) communicating a date and 2) doing it shorter than writing out the words.
