This is a language issue. DMY makes perfect sense in languages where you'd normally say the date in that sequence. The "problem" is that English doesn't do that. The natural flow in English is MDY, e.g. July 4th, 2024. That not how Germanic language (at least those I know) works. In Danish or German you'd say "4th July, 2024", that's just how those languages work.
I do agree that for computing ISO 8601 is the way to go as it sorts correctly.
I'm sure that's true. This seems more like US custom than the whole English language. "July 4th" sound a bit forced and not natural to me, and I am a native English speaker. Not US English though.
I accidentally an important word there. It should be "I'm not sure that's true." It's an English expression that's a bit understated: it means "I'm confident that this is wrong".
You can't always argue from "what feels natural" - that's prone to mere familiarity (1), and someone else who is more used to the other way will have the opposite "feel". It's subjective, and not universal.
In your English maybe. That’s just not a good argument.
