you should also always specify YYYY-MM-DD because often M and D ignores leading zeros, YY means the 2 digit suffix, and Y… well, i don’t even know what that is but i’m sure it’s something less specific than YYYY
if we’re going to be picky about being clear about things, let’s be truly clear about things
you should never make the assumption that software you use is smart, or even not complete garbage
…and file managers aren’t the only things that display lists of files. low-level tooling should not be “smart” beyond the most basic sorting without specifically being told first
sadly for everyone that’s factually incorrect, but the phrase DD/MM/YYYY > MM/DD/YYYY does not preclude YYYYMMDD > DD/MM/YYYY > MM/DD/YYYY
i reckon Y might be something like years since 1970 or some other epoch (we do things like week number of the year, day number of the year, etc so i think that’s kinda similar)
