"There shall be no other date formats before ISO8601. Remember this format and keep it as the system default"
Largest to smallest unit of time. It just makes sense.
Sorting by date would be so much better with yyyymmdd .
ISO 8601, while great, has too many formats. May I introduce RFC 3339 instead?

If you have years of files named similarly with the date, you will love the ISO standard and how it keeps things sorted and easy to read.
I have autohotkey configured to insert the current date in ISO 8601 format into my filenames on keyboard shortcut for just this reason. So organized. So pure.

Glad I can count my own country, Lithuania, among the enlightened.

YYYY-MM-DD:HH:MM:SS
Funny thing, in ISO 8601 date isn't separated by colon. The format is "YYYY-MM-DDTHH:MM:SS+hh:mm". Date is separated by "-", time is separated by ":", date and time are separated by "T" (which is the bit that a lot of people miss). Time zone indicator can also be just "Z" for UTC. Many of these can be omitted if dealing with lesser precision (e.g. HH:MM is a valid timestamp, YYYY-MM is a valid datestamp if referring to just a month). (OK so apparently if you really want to split hairs, timestamps are supposed to be THH:MM etc. Now that's a thing I've never seen anyone use.) Separators can also be omitted though that's apparently not recommended if quick human legibility is of concern. There's also YYYY-Wxx for week numbers.

DD/MM/YY and YY/MM/DD are the only acceptable ones IMO. Throwing a DD in between YY and MM is just weird since days move by faster so they should be at one of the ends and since YY moves the slowest it should be on the other end.
I'm not kidding when I ask: are there really a lot of people using MM/DD/YYYY??
I think most Americans do. Or at least it was taught that way in school when I was growing up. Maybe it’s because of the way we speak dates, like “October 23rd” or “May 9th, 2005”.
Regardless, the only true way to write dates is YYYY-MM-DD.

Pretty much every American I've ever met. Dates on drivers license, bank info, etc - all in MM/DD/YYYY ... or even just MM/DD/YY
I regularly confuse people with YYYY-MM-DD

ISO 8601 format is the best (YYYY-MM-DD).
Came here to say this. I try to name all my docs in the YYYY-MM-DD-descriptive-name.ext format.

YYYY-MM-DD (honestly without dashes) is the only helpful format.
If you name all your files with this as a suffix then your files automatically sort versions of themselves in order when sorting by name.
ISO 8601 baby
Though it ought to be a prefix, not a suffix
Came here to say this, I use DD.MM.YY in day-to-day stuff, but for files it's either YYYY_MM_DD or YY_MM_DD, the automatic ordering is beautiful

It actually makes sense when you put YYYY/MM/DD in filenames as they will be sorted pretty neat (ex: reports)

It is arguably the best way to name large sets of indexed files on a filesystem.
I think that the best argument is that it makes sense when combined with hours minutes and seconds.
yyyy/MM/dd hh:mm:ss
Goes from large to small units.

This meme implies there's an equal battle between MM/DD/YY and DD/MM/YY, which is nonsense. Much like imperial units, only 'murica uses MM/DD/YY.

When you're naming a file, you can't use anything else.
You're not wrong. through much trial and error in the 1990s I learned this was the most efficient & accurate & chronologically searchable way to date things.
YYYY-MM-DD for everything digital, DD-MM-YYYY for everything IRL.
I propose the use of MYDYDM format. So, October 15, 2023 will be written as 121350. Just to make it as confusing as possible.
And then convert that to hexadecimal, making it 1DA06

Iso date format. Anything to do with photos is best to have in this format at the start of the filename.

TBH, Japanese format makes sense when you use it to name files/directories, as sorting by "name" is equivalenti to sorting by "last modified".
equivalenti
Love typos that force me to read comments with an Italian accent
I'm actually italian, lol, but that was a genuine typo.

Japan I can get behind but MM/dd/yyyy is just evil, why would you sandwich days between months and years? You monster

Japan wins this one.
DD/MM for readability, YYYY/MM/DD for alphabetical sorting that's also chronological.
