I’m sorry but it doesn’t make sense TO ME. Based on what I was taught, regardless of the month, I think what matters first is to know what day of the month you are in, if at the beginning, in the middle or at the end of said month. After you know that, you can find out the month to know where you are in the year.
What is the benefit of doing it the other way around?
EDIT: To avoid misunderstandings:
- I am NOT making fun OF ANYONE.
- I am NOT negatively judging ANYTHING.
- I am totally open to being corrected and LEARN.
- This post is out of pure and honest CURIOSITY.
So PLEASE, don’t take it the wrong way.
Ignoring the coding side of things…
It’s relative. And also works easier to navigate the calendar. If we’re planning something for next year I pull up next year’s calendar. If it’s this years and we’re planning something for later this year, when I hear you say August, that’s the month I go to. But if you say the 27th of August, The first thing I heard was the 27th which could possibly be this month or next month if it’s say the 28th today.
American here. No idea. Either DD/MM/YYYY or YYYY/MM/DD are more logical, but here we are. When naming/renaming files and including a date in the name, I’ll usually do YYYYMMDD format somewhere. If I’m emailing/texting others, I use MM/DD/YYYY.
Fun little story, the department I work in recently began to work with some people over in the UK, and even though I brought up the date format differences, we’ve already had someone of gett the month and day flipped and it caused some confusion on our end.
Year is the most significant (read: big) unit in the list, but it is the least significant (pertinent to daily life) unless you’re a time traveler. Of month and day, month is more significant than day in both size and pertinence, so it gets ordered first. But when sorting things into folders or file naming conventions, biggest category is always the best.
You articulated what I was thinking, better than I could have. This is it for me.
I’d add that there’s probably a lot of habit involved, plus the fact that everyone else does it.
So not only am I not used to saying “today is the 4th of May”, everyone around me isn’t used to hearing it either and might think I’m being weird.
To make sure its not December right away. Fuck that entire month. Everyone hates December so much they throw the years biggest party at the end of it.
I write the date a bit different depending on which format its going on.
For example, computers like to sort things alphabetically. If I’m writing electronic diary entries, I’ll name the document as “2025-06-01.”
If I’m hand signing a legal document, I prefer to sign it as “01JUN2025” or “01JUN25” if space is an issue.
If the format is preselected and deviation isn’t allowed, I’ll just write it like everyone else does.
Personally, I like dating things in ascending or descending order. Day month year, or year month day.
I’m a fan of the 01JUN2025 format. It’s unambiguous and uses about the same space as other traditional formats.

Hey! Me too! 🤝
Most significant digits first. You write the thousands place before the hundreds, you write the month before the day. Of course, the whole argument is blow away when you write the year at the end instead of the beginning. (ISO YYYY-MM-DD dates for the win.)

Most significant digits first.
That would only make sense if the US wrote the year first, but they don’t. They just seem to slap the date together in a random order
I think that’s context relevant though. If we think about when dates are most frequently used (news, business, planning) it’s typically within the year (or month will give context).
That added with the fact it’s not uncommon in some situations to just provide month/day.
That being said, I don’t think either is better or worse. Just a preference kinda thing, unlike the issue between metric and imperial units.
regardless of the month, I think what matters first is to know what day of the month you are in
You’re telling me that if you have a list of scheduled dates in the near future to meet with clients/patients/whatever, you first want them sorted by day, and then month?
So this list is the order you want to see these in?
- 4/5/25
- 8/7/25
- 15/6/25
- 16/5/25
- 23/6/25
Doesn’t it make way more sense to see them sorted by month first, then day, so that they’re actually in chronological order.
- 5/4/25
- 5/16/25
- 6/15/25
- 6/23/25
- 7/8/25
The only way you could defend the former listing is if you’re also arguing that it makes sense to sort the list by the middle column, and hopefully we all agree that is just absurd. We don’t alphabetize people by their middle names. You don’t look up a word in the dictionary starting with the letter in the middle.
I jest, but I think this illustrates a real-life, commonplace example of when it makes sense. I agree that MM/DD/YYYY is not in order of magnitude, but I do believe it’s in order of most significance to least significance given the timescales we are typically dealing with.
Such a waste. 2025-06-01. Easy. Chronological.
So,
- OP is asking why month before day rather than day before month
- In your example, it’s not clear whether you are doing Y-M-D or Y-D-M, but I assume you are putting month before day, so we agree on that part. But
- I think we’re all in favor of: Most significant on the left -> Least significant on the right. I’m just arguing that, most if the time, for the most common uses, Month is most significant. It’s just more common that you’re looking at a list of dates that all span the next few months than a list of dates that are all within this month, or beyond a year.
ITT: defensive answers and ISO-8601 supporters.
Yes, I didn’t quite calculate how controversial the topic would be, my bad…
I think the clear answer is that there is no real reason other than habit and sunk cost fallacy.
See also the metric system, A4 paper, and daylight-saving time.
I’m not Mexican, but this reminds me of a Mexican ranchera that says “No cabe duda que es verdad que la costumbre es más fuerte que el amor” (There is no doubt that it is true that habit is stronger than love).
My guess is the month is most relevant to an agrarian society. It tells you where you are in the growing cycle that the entire culture revolves around. The day and year offer little practical utility to a 19th century farmer.
Oh, that make more sense and seems plausible! Thanks!
You already answered your own question, bud.
it doesn’t make sense TO ME. Based on what I was taught
Why do you think other people are different than you?
I’m just curious… Is that a crime?
The short answer is, it’s what we were taught in school. Like many preferences, it’s shaped by the culture we grow up and live in.
I’m sorry but it doesn’t make sense to me.
Of course not, you were raised and live in a different culture; so, your preferences are different.
Ultimately, the right answer is ISO8601. It’s unambiguous and sorts well on computers. But, I don’t think any culture is teaching that as the primary way to write dates, so we’re stuck with the crappy ways.
YYYYMMDD is commonly used throughout East Asia.
There is an American subculture teaching and using ISO 8601; the US military. They don’t call it that, but I learned later that’s what it is. They enforce YYYY-MM-DD on all documents.
Am American and I hate the MM/DD/YY(YY) format. Unfortunately its what’s been taught and used as the standard date format for a long time.
I much prefer the ISO standard of YYYY-MM-DD. It’s the superior format logically moving from the largest calendar unit to the smallest. Also superior for date ordering files.
Yeah, I resently saw it and I agree with you.
Why, when you want to know the time, do you read the hours first then the minutes? Why not just read the minutes and then figure out the hour you’re in?
Convenience…? Is it more convenient to know the month first and the day second? (That’s literally what I’m just asking! No shade! No judge! Only curiosity!)
As an American it was just what we were taught. However, when I started creating code and being pedantic about organizing files by date, I now prefer YYYYMMDD format as it is, chronologically speaking, superior when prefacing files with it. In this case, in my opinion, it’s better to have the year and then month first prior to day.
To each their own, variety is the spice of life.
This is the only format that truly makes sense, as it is both unambiguous and, as you noted, sortable.
What you say is interesting. Having a way of organizing time that suits your needs. That’s why I asked if there was any benefit in the way Americans (and apparently also Chinese) represent time.
Interesting thing about how Chinese time is organized is locations are also stated big to small. Last names then first names etc.
Locations have a last name and a first name in Chinese?
I mean the larger family name comes before the personal name. Implying a connection between number, place, and naming sequences
Chinese is also weird imho. If I remember correctly, they put the details of an action first in a sentece and the verb that defines the action itself goes last with some exceptions.
Hungarian comes to my mind which is similar and always follows the context first, details later rule. They use “yyyy.mm.dd.”, “family name first, given name last”, “country, city, street, street number order for locations”, and the word order of their grammar is similar too, details are always at the end of the sentence.
China’s first name is actually Jim, believe it or not.
ISO is my true north.
It’s not just Americans. There are many countries in Asia where the default is year month day. If you ever had to organize files by name and date this is the supreme sorting order. Both Europe and North America are getting it wrong.
If this gets you mad don’t ever look into how the French count from 80 to 99. Or how languages disagree on what’s blue or green. These things happen.
I know about the Asians. I work in a Chinese run company and we use WeChat for internal communications. When I have to search for a message from a specific date I always get confused by the way the dates are displayed.
