Why is it that Americans refer to 24 hour time as military time? I understand that the military uses the 24hr format but I don’t understand why the general public would refer to it like that?
It makes it seem like it’s a foreign concept where as in a lot of countries it’s the norm.

Because the average American is much more likely to bump into American military personnel than people from countries that use 24 hour time. It’s really as simple as that.
And this isn’t because we’re uncultured swine, it’s because we’re separated by two oceans from most countries.
The entirety of South America uses 24hr time.
Which is a few countries south of the US and connected to NA by a nearly impassible forest and no roads… Might as well be another ocean.

Australia isn’t real.
Paradise, Heaven, Eden, Australia, whatever it is.
It’s a penal colony…
The entire US logistics chain runs on 24 hour time, even the 100% domestic aspects.
The logistics chain would also save tens of billions of dollars in lost revenue every year if we ended daylight savings time and time zones, and collectively is one of the biggest lobbies for those changes
I would love to know why if you have more info to share
Logistics uses 24 hr clocks to be as precise as possible
The reasoning for lost revenue is a long story, but to heavily TLDR it, the entire logistics chain is basically a giant house of cards, and every mistake compounds repeatedly. Everything from a scheduling error at one warehouse to a driver not knowing about weird time zones (like AZ), to international miscommunications, all pile up on both their own individual load/order and every other step in the chain. A mistake at one manufacturer rolls to the next manufacturer, which then snowballs to the receiver, influencing timing on the last mile delivery.
Because of the heavily interconnected nature, any mistake in documentation, ordering, or timing causes significant delays and missed revenue elsewhere.
Thank you! That makes sense, i appreciate your time and thoroughness of your response!
Lots of good answers here, but I don’t see anyone mentioning the minor differences between military time and 24 hour. With military time, they don’t use a colon when writing it, and they always verbally say the leading zero. So a time using a 24 hour clock is written 06:00 or 6:00 and said verbally as “six o’clock”, but with military time, it is written as 0600 and said verbally as “Oh six hundred hours”.
That’s it. That’s the only difference. Though many Americans do indeed incorrectly call any 24 hour clock “military time”. I myself used to say it incorrectly when I was a kid because my parents said it incorrectly.
Related question. Do 24 hour clock folks say fourteen o’clock if they’re talking about 2pm?
I’m german. if it’s completely unambiguous, we simply say “dinner is at 6” or “my shift ends at 4”. but when you want to make sure that there’s no room for confusion we say “let’s meet at 21 o’clock”.
I’m Dutch. Usually we just say something like “2 in the afternoon” instead of 14:00 or 2 PM. But digital clocks and writing etc will use 24 hours. Every now and then people will use it though, saying 14:30 as “fourteen hours thirty”, but that’s quite rare and sounds a bit formal (or goofy).
In France, people commonly use the 24h format. Any time given in a formal setting (given on TV, opening hours for a business, etc.) will be in 24h format. Some people still use 12h though.
In French, it’s pretty common to say 14 o’clock.
La fête est à quatorze heures.
Which is French for “I expect you’ll show up some time between 15:00 and 19:00.”
In my country younger individuals like me use the 24 hour system a lot verbally. Older generations from before smartphones (which always use 24 hour) uses the 12 hour system more.
But in general I would argue that people use the 24 hour system when talking about something which needs precision, like when the train arrives. And the 12 hour system when talking about something like when to meet a friend (it’s still very important to arrive on time though, regardless of how imprecise the time was, “about five” means five.)
I’m a nurse who uses 24-hr time at work and it’s about 50/50 with me saying “fourteen hundred” or “2pm” when speaking. I generally find that my colleagues understand both and use both interchangeably.
They say fourteen hundred or 2 o’clock. I’ve never really heard anyone say 14 o’clock.
We definitely just called it 14 where I grew up
We called it 14 in Alabama. You’re talking about age of censent, right?
In both Polish and German people say fourteen o’clock.
In Denmark we say “2 o’clock” or just “14”, sometimes also “14 o’clock”. No one says fourteen hundred, except perhaps for a few military wannabes.
If it’s quarter past 2, we’d usually say “14-15”. Half past 2 would be “14-30”, you get the idea.
If we mean to say “from 2 o’clock to 3 o’clock”, we’ll say “14 to 15”, which I imagine can be confusing for the uninitiated, as the only difference from “quarter past 2” would be a “to”.
For those downvoting me, what do you say? I imagine it must be other Danes or neighboring countries, as one surely wouldn’t downvote a culturally dependant statement if not from said culture.
Same in Norway, unsurprisingly, but we do say 14 0 0 (fjorten null null) if making it clear that we mean 1400 exact. Otherwise like you said, klokken 14 or klokken 2.
I basically always write the time as a four-figure number, and verbally refer to 1400 as “two o’clock”, “two in the afternoon” etc. in English but “viertien uur” or “twee uur” in Dutch.
Edit: I used to work in a train station in the UK, and we’d always say train times as (one- or two-figure number)(0 like “o” if it’s there)(one- or two-figure number). So 1400 is fourteen-o-o, 1407 is fourteen-o-seven, 1412 is fourteen twelve, 0502 is five-o-two. Among staff, we’d refer to them just by the minutes, so the o-two, the seventeen, the forty-eight, etc.
1400 (fourteen hundred)
Like the bastardization of the 24h clock by the television companies, doesn’t Amarican military time also allow for relative time instead of absolute? Like writing 5:00 on the second day of a time critical mission as 2900?
I’m pretty sure I heard this somewhere, though I have yet to verify this claim.
Sort of? Ime you’ll sometimes hear/see things like T+2900, meaning 2900 minutes after T (T being a common placeholder for “the moment the operation began”). But unless the mission started at 0000, T+2900 doesn’t mean 0500, it means +2900 since T
By the time I solve for T, the mission will be over.
I guess that does make sense, and definitely not as bad as I had misunderstood it to be.
It feels a little weird, and I’m not sure if T+29:00 or equivalents are allowed in ISO 8601, but I have seen computer programs that represent time differences in similar ways.
Thank you for the clarification!
So they say 17 o’clock?
Mil - seventeen-hundred Civ - seventeen-o’clock
As a civilian who uses the 24h system, I say “five o’clock”, but write “1700”
I say 17 o’clock.
Doesn’t military time also use 24th hour followed by hour 1 instead of 0?
Army here, we always say 0000 for midnight, but honestly that’s probably just because it’s what our phones and watches call it. Perhaps it was different before electronic timekeeping was the norm.
That’s interesting. Marine here and once when I was deployed and writing up “significant event” reports for briefs, the Watch Officer never wanted to say 0000. He thought it would be too confusing when looking back and trying to figure which day it actually was. Is 0000 on 20231023 Monday at midnight or Sunday at midnight? He had us use either 2359 or 0001 and the date to clarify. 0000 didn’t exist for him, but it might have just been his own personal pet peeve.
It’s pretty commonly done with 12hr time too, for the same reason: to help protect against stupidity.
00:00 is the time with the new (“tomorrow”) date, 24:00 is the time with the old (“yesterday”) date.
24:00 isnt really used, in my experience. Also, many people dont mentally switch dates until they went to bed.
Watch officers HATE this one ambiguous millitary time/dating convention
That’s interesting. How do they say it out loud? If 6am / 6:00 / 0600 is said “oh six hundred”, is 0000 “oh oh hundred”? “oh zero hundred”? “zero thousand”? “quadruple oh”?
Oh-zero-hundred or zero-hundred if we gotta. Generally… Midnight lol
oh oh oh oh
zero zero zero zero
oh zero hundred
midnight
twelve
what a trip
Zero-Dark-Thirty
Given how they use different systems to measure almost everything than the rest of the world, I’d say I’m OK with them not using the 24h format, I’d expect them to use something like the 27 American hours, divided in 109 minutes of 31 seconds each.
You mean the 50 hour freedom clock? One hour for each state, yee-haw!
You mean freedom minutes, right??
Sorry, you’re right. And stars and stripes minutes
The freedom clock, where hours are called “freedoms”, minutes are called “stars” and seconds are called “stripes”.
Stop giving them ideas!
Ljbol
Agreed
HOOAH
Its because in America most people’s only experience with it is when the movie says “meet here at 0700 hrs.” Really isn’t much deeper than that, we also call “ranger green” “ranger green” whether an army ranger is wearing it or not, despite it really being “just a shade of green.” Sometimes things are just called things.
If this was a case of things just being called things, it would be its own word. For example, a door is called a door because things are just called things. But military time is obviously a reference to something entirely different, that doesn’t actually have anything to do with time. So there’s more to it than just being called that.
Ranger green is called like that, because it’s the shade of green rangers wear. And not “just because”. Same with military time. It’s called like that because people associate it with military, be it from seeing it in military movies, or by using it in the military themselves.
Ah but when is a door not a door?
When it’s ajar.
Where’s lemmy gold when we need it?
+10pts
When it’s a window.
There is no spoon.
When it’s a painting
“Ranger Green” the hell is that?
I’m an army veteran and I’ve never heard that term. Army Green, yes, but that’s pretty rare, too.
What color even is “Ranger Green” other than OD?
Do I look like a swatch to you?
Just remember, civilian Americans aren’t the one who named the time system that includes “Oh Six Hundred Hours” Military Time. It was the Goddamned Military. And when the Goddamned Military fucking tells you what something is called, you fucking call it that. No questions.
So we could flip our clock displays to 24 hour time and meet at 14 o’clock, but we’d still be civilians and unworthy to use Military Time. So why bother? Working 9 to 5 is bad enough, working 9 to 17 sounds too fucking exhausting.
Wow, 9-17 really does sound like a long fucking day, whereas 9-5 sounds way shorter.
But they’re both the same and both far too much time spent at work.
8 hours vs. -4 hours. I know what shift I’m picking, suckers.
0900-1700
The military have longer days than us plebs. They have twenty-four hundred hours when we get a measly twenty-four.
Unfair.
It’s called genericide. They encounter the 24 hour measure of time primarily through the US military and its service members so all 24 hour time generally gets called military time.
Similar to why facial tissue is often Kleenex or adhesive bandages are Band-aids in the US.
Hardcore name
I was worried for all the geners.
Here in California, I’ve heard both “military time” and “24 hour time” used interchangeably for writing the time as “03:45” or “16:20”. That said, I’ve heard – citation needed – that proper military time does not use the colon, such as “1600”, pronounced as “sixteen hundred hours”.
As for why the public might refer to this generally as “military time”, it may just be that that’s the most common, well-known use-case in the States, outside of the sciences. I personally use 24 hour time on all my devices, but I’ve come across many people who prefer clockfaces or AM/PM, probably out of habit.
By the book, you’re right. No colon when written, and if the last two digits aren’t “00” they are supposed to be pronounced individually.
4:45pm = 1645 = “Sixteen Four Five hours”. (Or “Fooor fife” if you’re a pedant about radios.)
That’s all well and good trivia, in practice it’s usually said “Sixteen forty five” because yeah ain’t nobody got time for all that.
As a fairly-new ham radio operator, I need to improve my numbers pronunciation so maybe I’ll start reading the time like that and see how other people react.
Already, I get a number of confused-then-resigned looks when saying “sixteen o’clock” haha
I’ve heard the same with regards to proper military time not having the colon.
In Switzerland it works like that too.
“Normal time” for us is 24h with colon so 18:00
While “Military time” is without colon, so 1800 and is then pronounced as achtzehnhundert (eighteen hundred).
We don’t use colons in our time in the American hospital system. We use them for a lot of other things though. (Pun)
It took me a second to realise what the pun was…
I spent 20 years in the US military. I had to quickly learn “military time” in order to function, as we were taught 12-hr time growing up in school. I was surprised when I traveled the world and discovered that everyone else uses “military time” (read: international time) as well. I guess Americans just really wanna do their own thing.
I exclusively use military time nowadays. If someone doesn’t understand the time I stated, I’ll correct it to 12-hr time on the spot, as converting is super easy. Just count back 2 hours and drop the 10’s digit by one; e.g. 1600 = 4 PM. 2200 = 10 PM. Etc.
Let’s go out to eat, I made reservations for 7.
Are we having breakfast or dinner?
Without context, tough to tell. That’s why 24hr is superior.
Lunch. It’s 7 people.
Dinner, because if it’s earlier than 7 AM and you’re inviting me to an impromptu breakfast, we’re not friends anymore, and I’m going back to sleep.
Saturday, I’m going to bed at 9. Forensic that one out.
Except that’s not actually an issue in practice. In a real-world conversation you would disambiguate with “Let’s get breakfast” or “Let’s get dinner” if you’re not referring to the immediate future. I honestly can’t think of a single time that I’ve been genuinely confused in this way.
Edit: Also, when would you ever make reservations for breakfast? Unless this is a joke that’s gone over my head.
Closest thing I can think of is making reservations for Brunch. Some places it’s necessary.
Brunch wouldn’t be at 7 though
When it’s unclear I’ll say 7 in the evening, or 7 in the morning, 7pm, 7am. 7 at night, supper at 7, whichever one isn’t pitch dark. There are many ways to go about it.
Local or Zulu?
Oh wow. That explains a lot. I always thought that when Americans said “military time”, they meant Zulu time, that is 24h time UTC.
TIL it’s just sparkling 24h local time.
Glad I’m not the only one. I also thought “military” was always UTC and “24” was local time.
The average American is likely to have more interaction with American service men and women than Europeans. Most Latin immigrants I know use the 12 hour clock. While the 24 hour clock is preferred in many countries, they are not the countries that immigrate to the US in large enough numbers to influence us or expose us to the 24 hour clock like our own military does.
Wait, how would you know whether migrants use the 24 hour clock?
You’re not supposed to say “we meet at fifteen thirty”, you just say half past three or, in non-English languages sometimes “three in the afternoon”.
You only write it as 24 hours because it saves you having to add extra letters to solve the ambiguity. When I interact with Americans I also write “three PM”, it’s just being polite.
You’re not supposed to say “we meet at fifteen thirty”, you just say half past three or, in non-English languages sometimes “three in the afternoon”.
Uh, why not? Absolutely you can say “half past 15 hours”, and plenty of places do.
I have all my clocks and watches set to 24h like a normal person and I’ve never heard a human being say that out loud or said it myself.
Outside of American movies featuring the military, I suppose, which answers the OP’s question.
Never seen that spoken myself. Do yo have any examples? I’m genuinely curious
IMHO, I don’t think that would change anything (with regards to immigrant influence).
EDIT For those downvoting me, I’ll explain it more for you. The vast majority of the world currently uses the metric system. Only three countries officially use the imperial system (UK has mixed usage, including them would bring the number to four.). If the majority of the world uses one system, and the US hasn’t changed, how will migrants influence the country enough to change?
Because that’s exactly how we see it. It IS a completely foreign concept. The general public does not use 24hr at all. The only time we ever hear it, is when someone in the military says it.
For the people where 24h time is normal …. Is that a more recent development it’s the ubiquity of digital clocks, or would people have also used 24h time with analog clocks, despite them not having a way to display that?
—- looking around, realizing I still hav analog clocks all over because I wanted my kids to be familiar with them. That boat sailed
I have owned multiple analog watches with a 24 hour face so it isn’t like they don’t exist they just are far from common place.
For the people where 24h time is normal …. Is that a more recent development it’s the ubiquity of digital clocks, or would people have also used 24h time with analog clocks, despite them not having a way to display that?
I’ve been born in central Europe in the 80’s before digital clocks became the norm. 24h was normal even then when writing the precise time. For example in TV schedules. When talking we normally use 12h but without adding AM or PM as it most often is obvious from the context. When it’s not then we add “in the morning” “at night”. Actually speaking time in a 24h format is very rare. But since it’s always encountered in writing, every child learns very early how the 24h system works.
Fascinating. Here in the US it seems similar when talking, but I almost never see 24 hour time, even in writing, except in “military” or similar context. Plus I really haven’t noticed any changes in these habits during my adult lifetime.
we have analog clocks because my wife has forbidden us from living in a minimalist glass and chrome cube where the only decoration is neon lighting and we only wear latex body suits and sunglasses indoors 😿
You have a very cool picture of the future though
In Brazil it has just always been this way. We have normal 12h clock faces and we are used to both 24h and 12h time. The curious thing is that we are used to read and write in 24h, but in speaking the vast majority uses 12h. Probably because it’s shorter to say “nove e meia” than “vinte e uma e trinta” for 09:30/21:30
Note Zulu Time (mission time) is equal to Greenwich Mean Time (GMT) everywhere in the world.
GMT observes daylight savings as it is in Greenwich England, this is not consistent between countries. UTC does not observe daylight savings.
Er, not sure if I understand you but In Greenwich we use GMT in winter and BST in summer so GMT doesn’t change.
Different countries that observe DTS pick different days to do the switches. Also the closer to the equator you wre the higher likelyhood they dont observe it at all.
The point is that GMT isn’t changing, the region is switching to an entirely different time zone, BST (British Summer Time). If your time is based on GMT, it won’t change due to British daylight saving time because GMT never changes.
For a similar example, in the part of the US that uses Mountain Time, states observe MST (Mountain Standard Time) in the winter, and most switch to MDT (Mountain Daylight Time) in the summer. However, Arizona doesn’t observe daylight saving time, so they remain on MST. MST always stays the same (GMT-7), the time is only changing because the states are observing a different time zone. The same happens with GMT and BST, it’s just harder to see because you can’t pick out areas that remain on GMT all year.
But in Europe we don’t say German Mean Time or Spanish Mean Time when changing to summer time. We increment GMT+1. So it becomes GMT+2. Then we revert back to GMT+1 in winter.
Incorrect - GMT is a timezone which the UK (and some other countries) observe in winter. In summer, the UK observes BST.
Good explanation here: https://www.timeanddate.com/time/gmt-utc-time.html
Thank you for the correction and the reference. The only time I can think of where these sort of distinction would come into play anyway would be if you asked a person in London the time from somewhere else vs. looking it up on a website. I dont exactly have any UK friends I call to look at clocks for me.
All time should work this way. 24 hr time running on GMT.
If someone in Cali wakes up at 1600, the only thing they change is their clocks and calendars, once.
We do all base our time off GMT +/- whatever your timezone is.
