Mm/dd/yyyy

If your filing you probably only have stacks of papers from this year so you put that at the end, and mm/dd is how everyone tells date

>YYYY:MM:DD-HH:MM:SS

>dd/yyyy/mm

M/d/y makes most sense. Month matters because if day is first, it could be any day of the week so its not useful. With month it gives you a good launching point.

>Ah yes, your appointment is on 2018 January 29th

>not using YYYYMMDD

It's ascending order of how many the number is out of. 12 months, 30/31 days, a fuckton of years. Out of context a month by itself, which will be read first, is a lot more useful to know than a day by itself

>set up bios date for my pc
>it's in mm/dd/yyyy format
>day ruined
if only Khrushchev pressed the button when he had opportunity...

dd/mm/yyyyyy

It only works with your language, though and it doesn’t make sense to type it that way even then.
