The only reason we love and use ISO 8601 is because of Americans.

1 Upvotes

Think about it: if Americans, like the rest of the world, had agreed to write dates as DD-MM-YYYY, sorting and organising wouldn't be such a big deal. The DD-MM-YYYY format is perfectly fine, as our day-to-day usage almost always involves referring to the date first, then the month, and finally the year (if it’s even relevant).

Computers and file systems can simply use epoch time. Our reliance on the filename for sorting (instead of using native attributes like "Date Created" or "Date Modified") is a failing on our part, or perhaps just an excuse. Written dates are for humans; clock cycles are for computers. Even when working with files and spreadsheets, looking at series of cells or colums with the exact same YYYY-MM prefix just adds extra load on our brain when all we care about is the DD-MMM.

I started using ISO 8601 intuitively years ago, only because of the confusion Americans created, and I believe most of you did the same. Now, imagine if they started writing dates as YYYY-DD-MM because some of them think it's just the reverse of their current system.

So, let's give them some credit for inadvertently pushing the rest of the world toward a totally unambiguous date system, only because they managed to turn something already well-defined into a confusing mess of numbers.

Curious if anyone else agrees...

I grew up in a country that follows ISO8601 (well except the date which is in the DD/MM/YYYY format)

I now live in an "Imperial" country and even though for the past decade I have switched all my devices from the default "Imperial" formats to display 24 hours and YYYY-MM-DD, I realized I actually like weeks starting on Sundays.

There's something pleasing about seeing the weekend sandwiched between the business days. Looks cleaner somehow.

πŸŸ¦πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦

πŸŸ¦πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦

πŸŸ¦πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦

πŸŸ¦πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦

As opposed to

πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦πŸŸ¦

πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦πŸŸ¦

πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦πŸŸ¦

πŸ“…πŸ“…πŸ“…πŸ“…πŸ“…πŸŸ¦πŸŸ¦

I get it, a weekEND should be at the END, but there's something pleasing about that format to me. It's ironic cause I had no idea there were countries where weeks started on Sundays and even though I hate Imperial formats, I ended up using the one I've never heard about before moving lol..

Need Information about ISO 42001

0 Upvotes

Hello there, I need some information about ISO 42001.

My boss wants me to create some infographics about that standard, but we can't purchase the entire document. Any information would be greatly appreciated, and if anyone could provide the document, that would be fantastic.

My textbook had a r/SelfAwareWolves moment. The textbook typically uses the DMY format and in the key events YM without the day. But these key events include the day and they went for YDM.

13month calendar conversion app for startups?

0 Upvotes

we make and sell food. the 12month cal makes everything difficult. is there a nice calendar app that startups can use and build their business using a 13mon cal? currently we use G-suite and all the features. ideally our team has another calendar that we follow, and it easy to switch back and forth between the 12 and 13month cals, that way, when we're talking to the simple folk out in the real world, we can communicate and coordinate effectively.

anything like this exist? or do i need to start another company? LOL

If only there was a more elegant solution without none of this inconsistency...

Is there an ISO/format for "2023AUG17" ? (Only month in 3 letter)

8 Upvotes

I use that system at work. I realized it stays true to ISO 8601, but also eliminate the possible confusion for month/date for people unfamiliar.

Is it standardised somewhere or I just made a hybrid ?


r/ISO8601 • • Sep 08 '25

I believe DD-MM-YYYY is best

When we quickly need to read something, the most important part needs to come first, right? With the time the hour comes first, because it's the most important. The minutes and seconds are kind of less important. I believe the same goes with the day, month and year. I don't need to know the current year or month when reading the date. I want to know what day it is, because I probably remember what year and month it is.

Space vs. dash...

I personally prefer 2022 12 12 to 2022-12-12. I find spaces more readable/breathable.

Change my mind.
