US date/time is actually closer to the ideal notation if you consider that for the majority of date references you don't need the year, so July 4th at 12:45:59 actually makes sense and denotes time from most to least significant digit. If you just shift the year to the front, you have an ideal naming convention and no confusion in identifying month and day.
In European, the date goes from least significant to most significant digits for the year and most to least significant for the time. For all the valid arguments on the side of the metric system vs imperial, if you ever want to shut the argument down for date formatting just ask why they don't keep the same format for date as they do for time, say 59:45:12 4/7/2023? For consistency that is how they should write 59 seconds after 45 minutes after the 12th hour of the 4th day of the 7th month of the year 2023.

This isn't true, the most and least significant parts of a date and time vary dramatically depending on context, and required specificity.
In day to day conversation, the day is the most important, to the extent that people often won't use the date at all but the day of the week, "we're doing X on wednesday evening", etc. The year is a given, and the month doesn't matter because it's either the same, or the next one because tomorrow is the 1st or whatever.
If you're talking about gardening or something broadly seasonal, month is the most important. It doesn't matter if you plant the seeds on the 10th or the 20th, but it should be during February. And obviously years matter when you're talking about things that happened a while ago, and decades if it's a long time, centuries for longer, etc etc.
Having a format that consistently increases, or decreases, specificity over it's length makes sense. Having one that muddles it up is very weird.
Well we agree on the last sentence anyway, but that also illustrates why both D/M/Y and M/D/Y are bad choices.... Because in the cases where you need the year, it means it figures in somehow and you're putting it last.
If the day is the most important, you just say 'the 15th' or 'Wednesday' or whatever. If the month is important, you can say 'May 15th' or the 15th of May (or, I guess 15 May?). But in the US we literally write like that. If the date is all you need, you say the date, if the month is important you give that info first (since if there is going to be confusion over the month, that's more important) so we say the month, then the date. IF we'd gone further and continued that path and actually wrote it YMD, we would have definitely won the high ground and settled our way as better, but because we decided the year could go at the end, we muddied things up and arguable came in second place...but we came in second place to an almost equally dumb, but one step more consistent, format.
DMY:HMS is still really dumb. Just that MDY:HMS is one step dumber.
just ask why they don't keep the same format for date as they do for time, say 59:45:12 4/7/2023? For consistency that is how they should write 59 seconds after 45 minutes after the 12th hour of the 4th day of the 7th month of the year 2023.
By that logic, that time should be written as 45:59:12 in Imperial.
:) fair point...I do admit that MDY is dumb, my only real argument is that MD makes more sense, and that is what is used in the US. The fact that our next step is MDY instead of YMD loses all the credibility, and Minute:Second:Hour is a funny and well deserved mockery of that.
