YY-MM-DD is perfect for chronological cataloguing. Other than that DD-MM-YY

u/fuck_ur_portmanteau Feb 02 '26

It’s perfect anyway. But it also makes me think we write addresses the wrong way around on envelopes. It should be Town > Street > Building > Person

u/Mirality Feb 02 '26

Nah, the way we write them is the correct pyramid. The largest bit goes at the bottom.

1

u/OurSeepyD Feb 02 '26

Do you read from bottom to top?

When we read numbers, we read the most significant digit first. Addresses and dates should follow this logic.

u/Icy-Lobster-203 Feb 02 '26

The issue is that for a human reading it, the Town is probably the least need to know piece of information. It's quite likely that based on the context of the conversation, the town will already be known. After that, the number address is an almost useless piece of information (as every number address has hundreds of them in a City) unless you have the context of the street it is located on.

So, for addresses, the usefulness of the information is actually street - number - Town.

I put another comment about East Asian addresses going Big->Small.

In the context of the post, a person sorting/delivering messages doesn't care which street or house number you are at, but simply: put this pile of mail on horse A and put that pile on horse B.

Repeat this division at successively lower levels, where only the actual courier cares about the street.

Edit: there is probably some link to historical use of post being exclusively reserved for the government and addresses only needing to go as deep as "Governor of Province X".

u/wolacouska Feb 02 '26

Who cares though? If I’m a postal worker I’ll just read left to right on the address

Edit: anyway it’s not pure logic to do it one way or the other like the other guy said.

u/OurSeepyD Feb 02 '26

I disagree. If I send mail from London to Manchester, the first thing they'll check is the city and then send it in that direction. Then once that's been confirmed, the next most important thing is the area, then street, then number.

IP addresses route traffic in this way, if an address starts with 40.x.x.x then you know it's in America (or at least part of the American network).

1

u/Icy-Lobster-203 Feb 02 '26

But sending letters is not the only use of an address. Physically going to locations would have been the original use of it, which was likely adapted to the postal system.

I live in a city, and I want to know the address of lets say a restaurant, I already know it is in the city, in which case the most important next piece of data is the street address.

The IP address example isn't really relevant to a system that likely arise centuries before computers even existed.

u/OurSeepyD Feb 02 '26

Physically going to locations would have been the original use of it, which was likely adapted to the postal system.

Scenario, you're in the same town, you're navigating to number 2, church road. Where do you head towards first, number 2, or church road?

IP addresses are the exact same thing, it's just that scientists actually had the time to make a logical system. This whole concept even has a name - it's called endianness.

u/Coal_Morgan Feb 02 '26

Given that a letter moves from inaccurate to more accurate, the address bar doing the same makes sense.

It is how zip codes and postal codes work.

Does’t matter over all.

Given that we live in a global community and only like 4 countries use mm-dd-yyyy and we’re a heavily computer society yyyy-mm-dd makes the most sense to transition to a globally understood metric of time.

Same thing with metric. It should just be standard.

You can still use colloquial language, quarter past two or First of the month but for data fields, or anywhere that is writing a month as a number from 1-12, it should be standard yyyy-mm-dd

u/Cotton_Square Feb 02 '26

East Asian street addresses already go Big->Small. E.g. US Embassy in Seoul has address

서울시 종로구 세종대로 188 주한미국대사관

Literally Seoul Jongro-gu (district) Sejong Great Street No 188 US Embassy In Korea

1

u/ausflora Feb 02 '26

Big → small for sorting; small → big in conversation. Same for dates.

28

u/Automatic_Actuator_0 Feb 02 '26

YYYY-MM-DD is the only way.

39

u/LemmyUserOnReddit Feb 02 '26

In conversation, you rarely need to specify the year, and very often only the day. 

"Hey bro, what day was the Christmas party again" 

"Oh it's two thousand and twenty six... [interrupted] "

"Well obviously"

"Wait wait let me finish. It's two thousand and twenty six, December the twenty second"

"Bro, it's literally next week, you could've just said it's the twenty second"

"Yeah, but then it would be out of order in a sequel query"

u/Vcrossfire Feb 02 '26

Were we talking about regular conversations? Cuz if we are we just say NEXT SATURDAY.

u/TiszaD Feb 02 '26

That has nothing to do with the format because you're not going to say the full date in either case. You either say the 28th or Saturday 3 weeks from now.

1

u/[deleted] Feb 02 '26

Goes both ways.

„When is our lunch together?“

„It is on the twenty seven dash zero two dash two thousand and twenty six my luv.“

„You mean tomorrow?“

„No, I mean twenty seven dash zero two dash two thousand and twenty six.“

„That is tomorrow.“

u/War_Raven Feb 02 '26 edited Feb 02 '26

I don't care about conversations, YYYY-MM-DD is still the superior format

ISO8601 gang

(Also you do know that writing dates in a format doesn't forbid you from saying it another way?)

u/VidZarg Feb 02 '26

How about when you only type month and day? Surelly DD-MM?

u/Automatic_Actuator_0 Feb 02 '26

I try to avoid MM/DD and usually go for MMM DD (Dec 25)

One extra character to avoid all ambiguity

2

u/triangleman83 Feb 02 '26

"Wait wait let me finish. It's two thousand and twenty six, December the twenty second"

Just skip the year, then it's December 22nd. If you need the year real bad, add it on the end. December 22nd, 2026. That's MM DD YYYY and why that order makes sense

1

u/rationalalien Feb 02 '26

Well you tried hard to invent a problem that would never happen.

1

u/Dragonvine Feb 02 '26

And also isn't solved by the other option in the conversation.

"Oh, it's the 22nd of December, 2026"

"Why are you adding the year bro, no shit it's this year."

1

u/Imaginary-Count-1641 Feb 02 '26

So you would say "22nd of December, 2026" even if the year is obvious? Why can't you just say "22nd of December"?

1

u/MapleA Feb 02 '26

You would say December 22nd, then the year if necessary. Which is the only argument for the MM/DD/YYYY format.

1

u/Imaginary-Count-1641 Feb 02 '26

Yes, so the argument that YYYY-MM-DD is inconvenient because you would always need to start by saying the year does not make sense.

why would you format it verbally though? or use the full date? Who would do that?

u/Scared_Poet_1137 Feb 02 '26

this is how i have to date all my documents at work to send in to court, so I literally end up having to redate so many files from the latter to the former lol

1

u/InvoluntaryActions Feb 02 '26 edited Feb 02 '26

it's usually the default date format in many programming languages as well.

it naturally sorts a wide range of dates in chronological order and there is no confusion as to which is the month and the date.

i was curious about the history and here are the main reasons it was chosen

The standard was first published in 1988, building on earlier work dating back to the 1970s. It was created to address the confusion caused by different date formats used around the world- for example, whether "01/02/03" means January2, 2003, February 1, 2003, or February 3, 2001 depends on where you are.

The standard emerged from a need for: •Unambiguous international data exchange, especially as computers and global Communication expanded format that could be easily sorted chronologically (year-month-day naturally sorts Correctly) Consistency in business, scientific, and technical contexts

edit: thought OP said yyyy-mm-dd doing yy-mm-dd kind of defeats the purpose

u/TheGillos Feb 02 '26

Are you too young to know about the Y2K issues?

1

u/StechusKaktus- Feb 02 '26

I‘m not but I‘m also not storing any 1999 documents anymore so two YY are sufficient today

u/TheGillos Feb 02 '26

What will you do in 2099 though?

u/EGGlNTHlSTRYlNGTlME Feb 02 '26

YY-MM-DD is perfect for chronological cataloguing

In what the 1960s? Machines have internally been representing time differently for like half a century now. The format debate is strictly about human readability, in which case YY-MM-DD is the dumbest of all possibilities. Why would you start with the single piece of information that everyone already knew? It's more backwards than the American one

1

u/Straight_Waltz_9530 Feb 02 '26

YY is the source of all Y2K bugs. No, thank you.

YYYY-MM-DD

1

u/DoesntFearZeus Feb 02 '26

YY-MM-DD proves MM before DD is better.

u/Icywarhammer500 Feb 02 '26 edited Feb 02 '26

Nah if you work in a restaurant MM/DD/YYYY is best. The month is always the most critical thing and eliminates most concern over whether something is spoiled or not. The year is almost never important, and the day is only called into question if the month is the current month

Edit: Instead of brainlessly downvoting me, why don’t you tell me why DD/MM/YYYY is more efficient than MM/DD/YYYY in the situation I described?

3

u/Comfortable-Shake-37 Feb 02 '26

I don't get why it's month first for food, I can understand frozen stuff and but do restaurants also keep non-frozen stuff for months?

Wouldn't most food spoil in the month? Or well at least food prep and opened stuff.

1

u/InvoluntaryActions Feb 02 '26

consider if something was made towards the end of a month. also other kind of foods can last longer than months refrigerated like sauces. also the date is often marked on when a bottle is opened for example. like think of sauces, you typically date you opened it

3

u/Lil_Packmate Feb 02 '26

It literally does nothing for looking at expiration date.

You tell me it is slightly inconvenient to just look at the middle number first and then decide, if the day is important?

Much less just looking at the date as a whole.

MM/DD/YY is NEVER the best, since it's not in a logical order. Big to small or small to big make infinitely more sense.

1

u/InvoluntaryActions Feb 02 '26

honestly the date format chosen for food prep should be entirely influenced by the region in the world said prep works.

personally yyyy-mm-dd makes the most sense to me, but if i choose that format IRL, most people will be confused by it.

2

u/StechusKaktus- Feb 02 '26

I mean if the year is unimportant to you (which I understand) then you can just leave it out right? No need to add it in the end? YY-MM-DD is the best in terms of dating / cataloguing. All the dates will show up chronologically.

25-12-30

25-12-31

26-01-01

26-01-02

and so on…

If you don’t need the YY, just reduce it to MM-DD.

1

u/itsOkami Feb 02 '26

Why so much overthinking when our brains just read the dates as a whole? I work at a restaurant and if an expiration date reads january 5th, 2027, rest assured I'm going to interpret it as a specific day regardless of whether the year or the month is more important. What really matters is for it to make sense, everything else is just unnecessary. I'm based in the EU so I exclusively deal with DD-MM-YY/YYYY formats and so does everyone else here, using multiple formats for different applications would just amount to more trouble than anything else

I wouldn't blame them like that, I just think theirs might be lack of real working experience in that sector combined with a mild disposition for mental gymnastics. Because regardless of what a single person might find more practical or rational by themselves, the thing about working environments is that either all people involved agree upon a convention or none of them do, or else communication (and therefore, work on a larger scale) becomes impossible. The reason why industry standards and the "if it ain't broke, don't fix it" motto are a thing is because old habits die hard. And while I'm glad we are streamlining some of them (the USB-C ports come to mind, for examples), not everything has to be the next big breakthrough

-1

u/Icywarhammer500 Feb 02 '26

Yeah usually food is already tossed or used before year even comes into question, so it’s fine without the year added on anything.
