for me, the section that changes the most goes last..
in a whole year, the YYYY never changes, the MM changes only 12 times.. i never implementing the day.. there's only so many possibilities i could have had for saved files in June. i just go straight to description
I like that for files, but not for written documents. When I label things I try to use the most intuitive/least confusing way I can think of: DD mmm YYYY. This comment is posted on 23 NOV 2023, for example.
I do prefer the abbreviated month with the yyyy mmm dd format. It makes things relatively easy to sort but you also don't have to worry about confusing others if you are referring to the 10th month or day for example.
