There are a couple I have in mind. Like many techies, I am a huge fan of RSS for content distribution and XMPP for federated communication.
The really niche one I like is S-expressions as a data format and configuration in place of json, yaml, toml, etc.
I am a big fan of Plaintext formats, although I wish markdown had a few more features like tables.
The year is the information that most of the time is the least significant in a date, in day to day use.
DDMMYY is perfect for daily usage.
DDMMYY is perfect for daily usage.
Except that DDMMYY has the huge ambiguity issue of people potentially interpreting it as MMDDYY. And it’s not straight sortable.
My team switched to using YYYY-MM-DD in all our inner communication and documents. The “daily date use” is not the issue you think it is.

Yes and YYYY-MM-DD can potentially be interpreted as YYYY-DD-MM. So that is an zero argument.
I never said that the date format should never used, just that significants is a arbitrary value, what significant means depends on the context. If YYYY-MM-DD would be so great in everyday use then more or even most people would use it, because people, in general, tend to do things that make their life easier.
There is no superior date format, there are just date format that are better for specific use cases.

That is great for your team, but I don’t think that your team has a size large enough to have any kind of statistically relevance at all. So it is a great example for a specific use case but not an argument for general use at all.

No country uses “year day month” ordered dates as standard. "Month day year, " on the other hand, has huge use. It’s the conventions that cause the potential for ambiguity and confusion.

Entire countries, like China, Japan, Korea, etc., use YYYY-MM-DD as their date standard already.
My point was that once you adjust, it actually isn’t painful to use as it first appears it could be, and has great advantages. I didn’t say there wasn’t an adjustment hurdle that many people would bawk at.

Your day to day use isn’t everyone else’s. We use times for a lot more than “I wonder what day it is today.” When it comes to recording events, or planning future events, pretty much everyone needs to include the year. Getting things wrong by a single digit is presented exactly in order of significance in YYYY-MM-DD.
And no matter what, the first digit of a two-digit day or two-digit month is still more significant in a mathematical sense, even if you think that you’re more likely to need the day or the month. The 15th of May is only one digit off of the 5th of May, but that first digit in a DD/MM format is more significant in a mathematical sense and less likely to change on a day to day basis.
For any scheduled date it is irrelevant if you miss it for a day, a month or a year. So from that perspective every part of it is exactly the same, if the date is wrong then it is wrong. You say that it is sorted in the order of most significants, so for a date it is more significant if it happend 1024, 2024 or 9024? That may be relevant for historical or scientific purposes but not much people need that kind of precision. Most people use calendars for stuff days or month ahead or below, not years or decades.
If I get my tax bill, I don’t care for the year in the date because I know that the government wants the money this year not next or on ten. If I have a job interview, I don’t care for the year, the day and months is what is relevant. It has a reason why the year is often removed completely when dates are noted or made. Because it Is obvious.
Yes I can see why YYYY-MM-DD is nice for stuff like archiving purposes, it makes sorting and grouping very easy but there they already use the best system for the job.
For digital documents I would say that date and time information should be stored in a defined computer readable standard so that the document viewer can render or use it in any way needed. That could be swatch internet time as far as I care because hopefully I would never look at the raw data at all.

Most significant to least significant digit has a strict mathematical definition, that you don’t seem to be following, and applies to all numbers, not just numerical representations of dates.
And most importantly, the YYYY-MM-DD format is extensible into hh:mm:as too, within the same schema, out to the level of precision appropriate for the context. I can identify a specific year when the month doesn’t matter, a specific month when the day doesn’t matter, a specific day when the hour doesn’t matter, and on down to minutes, seconds, and decimal portions of seconds to whatever precision I’d like.
