Because humans are not computers. That scheme makes sense when you are filling out things that are not nearby in time. For example, filling in your birth date on tax forms.
Otherwise, humans don’t generally need the context of the year. The same is true of the month only if the context is clear (I’ll see you on the 20th implies the very next 20th). A year is much longer and most things are not planned out that far in advance. If they are, they often dont have precise dates in which case a month or even a quarter is more appropriate.
Time is also one of those things where humans are so used to contextual processing that representing the full date adds overhead. 2025/4/20, 4/20/2025, 20/4/2025 all take more processing than “the 20th” or “next Sunday”.
I worked for a company that did their dates multiple ways and it was fucking impossible to know what date was what. It was super frustrating. I’d prefer this, but if you don’t, at least keep it consistent once you start.
If a date starts with the year, everyone will know the thing after it is the month. I’ve never ever seen YYYY/DD/MM. That, to me, seems like it wouldn’t add additional confusion at least.
Why is the format not:
2025/4/12
Biggest time frame to smallest time frame (year, month, then day)?

As a computer scientist, I’ve been doing this everywhere for over 10 years already. Be the change you want to see in the world.

They flipped month and day. If it was the year, you’re right.
ISO Tanf rise up.
Also 2025/04/12
Issues with unix paths. I prefer 2025-04-12.
2009, got it
This is the way.
ISO8601 FTW!
Don’t forget leading zeroes, we’re not half assing this!
02025/04/012
For written format that is ideal but when talking about a date, say in two weeks time, saying the year is redundant.
In my computer engineering course this is literally how we were told to write the date on our lab reports.

my guess is order of relevance.
This is how I do it- my folders and files are super easy to find
Canada uses this
yyyy/mm/dd
