MM/DD/YYYY genuinely causes issues, because it’s very easily misread by the rest of the world, and vise versa for Americans.

I have been mislead more than once, because the MM and DD are both ≤ 12.

MM/DD/YYYY needs to die

Month Day YYYY is fine, because it’s unambiguous when the month is spelled out.

YYYY.MM.DD, or similar, is the only way to sort dates properly anyway.
