I just want to pick one so we finally can all agree on days like today, 2/2/26

February 2nd is better conversationally, so 2/2/26 instead of The Second of February, which is 2/2/26… wait…

I’ve always used YYYYMMDD. The military required it for all signed documents. As a dev it helps to keep track of file versions;

DD/MM/YY is the only sensible way to format a date – from the smallest time unit to the biggest time unit, in acending order.
R_Nelle on
For daily use DD/MM/YYYY is more useful cause year you know bro..
But for storage YYYY/MM/DD is more reliable and useful…
The other one doesn’t make sense

MDY is based on the order you say it. “February Second, Twenty Twenty-Six.” (Obviously, some people say “Second of February,” but the point stands that both of these are commonly used, just like how MDY and DMY are both commonly used.) I don’t understand why some people find this so difficult.

Month Day Year makes sense if you sort it in ascending descending format.
You don’t say 21st of June. You say June 21st and reads faster.

Mmhh… MM/DD/YY is better conversely, but not logically. If we sort time measures by how long a single unit lasts, we’d get Seconds:Minutes:Hours:Days:Months:Years. And tbf, logic is more universal that language.

just always use YYYYMMDD, because why would you sort your files in a random order. You can only properly sort it when using YYYYMMDD.

How about dd/yy/mm?

It’s just YY/MM/DD but we break it up with a comma so the most unchanging number comes last

MM/DD/YYYY makes sense when you think about how people actually talk. Saying “it’s February 2nd” is faster and simpler than saying “it’s the 2nd of February.” It’s only a two syllable difference but I don’t think I’ll ever say “it’s the (day) of (month),” I’ll always say “it’s (month) (day)”

MDY Is definitely the best, its from most importance to least importance in most functions. Most people know what year it is or if they dont they know the general time period.
If I told you “it happened on the 5th” youd immediately be thinking in your head “the 5th of what?” However if I just say “it happened in october” you generally don’t need me to tell you the day or year
RyCryst on
Nah fuck DD/MM/YY. Give me that YY/MM/DD also I come from a work background where we dont use numbers for the month. We use Jan, Feb, Ect. Im used to YY/Mon/DD

But when speaking most people I know say it month day year

Luckily we don’t use geometric shapes at all in writing down dates 🙄

I mean what’s the most useful information for most people operationally? What season is it? What part of the cycle, so month has the most information. That’s the ‘big’ question you need to get right for most things. Is your delivery on schedule in the right ball park. Then Day gives you specific info that’s really useful. Year typically isn’t that important for most communiques or it’s the big thing in which case you don’t need that other info.

The reason we format it that way in the US is because conversationally we say the month first and the day second.
Furthermore the process of switching it after it being so longstanding just isn’t worth the effort.
We understand that it’s day first in the rest of the world.
Idk why this along with rants about Imperial units have to come up in karma farming posts every other week.
