MM-DD-YY  is just as wrong as DD-MM-YY.

YY-MM-DD is the most logical as it arranges units from greatest to least significant, similar to the decimal place value system. Just as it is with timestamps: HH:MM:SS.

Another way to think about it is that if you were sorting log files or screenshots (with timestamps in their filename) lexicographically (or "alphabetically") they would also sort chronogically. I also realize this is an argument in favor of 24-hour time, which I don't use unless  I am putting timestamps in a file name for this exact reason.

No, it's not just as wrong. It's more wrong because it is out of sequence. DD-MM-YY is not the best format, for the reasons you state, but at least it is in a logical order: smallest, middle, largest. MM-DD-YY is in a dumb order: middle, smallest, largest. It makes no sense.

It might not make sense to you, but when we think of dates here in the US, month comes first since it's the big target and the date then provides added precision. The year is usually the current year, so it's only in the exception that the year notation takes on any importance. So you see, there are logical contortions we can use to justify any arbitrary notation. IMHO, saying that MMDDYY is "more wrong" than DDMMYY is splitting hairs. Both are wrong. If DDMMYY is less wrong, it isn't much less.

Like religion, one's preference is almost wholly based on what we are taught to prefer by our parents, teachers, etc. And also like religion, many are prone to defend that preference vigorously without much objective basis. The only notation that has any significant advantage that I can see is YYMMDD (HHSS) and is the only notation I use when identifying samples, etc. It wasn't until I started using spreadsheets about 30 year ago that I realized how badly my preconceived preference for MMDDYY was. Had I grown up with DDMMYY, that veil would have torn just as easily.

I'd say DDMMYY is less wrong because you're starting at one end and working your way through the broader categories, rather than starting in the middle and going both ways. Maybe you only need DD. Maybe you need DDMM, or all three/four. Although adding that 4th level it's out of order again. So best to use YYYYMMDD.

In a perfect world I'm YYYMMDD.  But since we're not in a perfect world, I do my best to use 3 letters for the month and all 4 digits for the year, so no matter the order it's not ambiguous.

Current preferred usage:  2007-JUL-07

Also 07-JUL-2007, or even JUL-07-2007.  Some look more awkward, but none are ambiguous.  Spare me from 07-07-07

I thought this is the general scientific method of describing dates.

Hey, 07-07-07 is pretty unambiguous!

Dunno.  I would have expected numbers to be the absolute standard, just because the letters are in English but the numbers are more universal.

Haha my cousin got married on 07-07-07.  How about those three special days, their 1 day, 1 month, and 1 year anniversaries?  I've seen engineered drawings that would describe all three of those dates as 08-07-07 on the same list, one after another.

Do you mean 1907, 2007, or 2107?

It's always more complicated than that.

Pretty, in this case, means, "All the ones I'm alive for." ;)

My son-in-law and his wife specifically selected 08/08/08 as a wedding date, to make anniversaries easier to remember!

Or we could do it Japanese-style and use a counter symbol (or unit suffix) for each time unit: i.e. 2018年07月11日, although that is admittedly cumbersome.

Turns out YYYY-MM-DD is the ISO standard?
