Reading the digits is only half the skill. The moment you have to say military time to a colleague, a dispatcher or a radio, a second set of conventions appears: whether the leading nought is zero or oh, whether 1745 is two numbers or four, whether the word hours belongs at the end, and what the letter tacked on after the digits is doing there. None of it is difficult, but getting it wrong marks you out immediately.
This guide covers the on-the-hour form, times with minutes, the zero-versus-oh question, when hours is said and when it is dropped, and how the NATO phonetic alphabet turns a time into a time zone. Read it alongside the live military time now clock and say each reading aloud as it changes.
How to Say Military Time on the Hour
On-the-hour times end in the word hundred. 0700 is zero seven hundred, 1300 is thirteen hundred, 1900 is nineteen hundred. The hundred stands in for the two zero minutes, and it is never used when real minutes are present.
Hours below ten are voiced digit by digit, so 0400 is zero four hundred rather than four hundred. Hours from ten upward are said as whole numbers: 1000 is ten hundred, 1500 is fifteen hundred, 2200 is twenty-two hundred. Midnight and noon are the two that people stumble over. 1200 is twelve hundred, straightforwardly, while 0000 is usually spoken as zero zero zero zero or simply as midnight, since zero hundred sounds wrong to most ears.
Zero Seven Hundred or Oh Seven Hundred?
Say zero. Voice procedure across the US Army, the US Navy and the Royal Navy treats zero as a distinct sound precisely because oh is also the letter O, and on a degraded radio link the two are indistinguishable.
That said, oh seven hundred is extremely common in ordinary speech, in civilian workplaces that have adopted the 24-hour clock, and in almost every film ever made about the military. Nobody will misunderstand you. The distinction matters when the message is being transmitted rather than spoken across a desk, which is why the same discipline gives us niner for nine, keeping it clear of the German nein on international frequencies used by air traffic control.
How to Say Military Time With Minutes
When minutes are present, drop the word hundred and say two numbers: 1745 is seventeen forty-five and 0915 is zero nine fifteen. The hour keeps its digit-by-digit form below ten, and the minutes are spoken as an ordinary two-digit number.
Minutes under ten need care. 1305 is thirteen zero five, not thirteen five, because the zero is part of the written value and dropping it invites a misheard time. Radio practice goes further and reads the whole group digit by digit, so a controller may issue 1430 as one four three zero. That style is deliberately monotonous: single digits carry through static in a way that fourteen thirty does not. Both forms describe the same four digits, and how to read military time covers what those digits mean before you have to voice them.
When Do You Say the Word Hours?
The word hours is optional and its use is a matter of service custom rather than correctness. United States Army briefings and written orders commonly say fourteen thirty hours; naval usage generally leaves it off; radio voice procedure omits it to save airtime.
There is one place it is genuinely useful: in a sentence where the number could otherwise be mistaken for a quantity. Move at nineteen hundred hours cannot be misheard as a count of anything, whereas a bare nineteen hundred occasionally can. Canadian Forces practice sits close to the American convention, while the Royal Navy leans towards the shorter form. If you are joining an established team, listen for a day and copy what you hear rather than importing a habit from elsewhere.
Saying the Zone Letter: Zulu and the NATO Phonetic Alphabet
A letter spoken after the digits names the time zone the reading belongs to. Zero six thirty Zulu means 0630 UTC, the zone of the Greenwich meridian, and Zulu is simply the NATO phonetic alphabet word for the letter Z.
The full system runs through the alphabet, with each letter standing for a whole-hour offset from UTC, and it is spoken rather than written wherever messages cross borders. Aviation depends on it: ICAO flight plans, air traffic control clearances and meteorological reports are all timed in Zulu so that a single figure means the same instant in every country the aircraft passes through. NATO signal traffic uses the same convention for the same reason. If you need the letters themselves, Zulu time explained sets out the whole A to Z scheme, and the Zulu time clock shows the current UTC reading.
Voicing Times Over a Radio
Radio work strips the spoken form back to its safest possible version: every digit separate, no contractions, no assumed context. A time that would be eighteen forty across a desk is transmitted as one eight four zero, because a listener only has to catch four independent sounds rather than parse two compound numbers.
Emergency medical services follow the same discipline for the same reason. A crew calling a time of arrival is creating a record that will be typed into a dispatch log and later read back in an audit, so the spoken figure and the written figure have to agree exactly. Ambulance and fire services in most English-speaking countries voice military time on air even where the surrounding paperwork still uses AM and PM, and the handover at the hospital door repeats it a third time. Any number that will be transcribed by someone who cannot ask you to repeat it should be given digit by digit.
Common Mistakes When You Say Military Time Aloud
Four habits account for most of the awkwardness:
- Adding AM or PM: saying eighteen hundred PM is redundant. The eighteen has already carried that information.
- Using hundred with real minutes: 1745 is not seventeen hundred forty-five. Hundred belongs only to times ending in double zero.
- Swallowing the leading zero:seven hundred for 0700 loses the digit that makes the form four characters long.
- Skipping the zone letter: in any message that will be read elsewhere, an unmarked time is assumed local, and that assumption is how missed rendezvous happen.
The underlying reason for all of this precision is the same one that put the format in uniform in the first place, examined in why the military uses 24-hour time.
Conclusion
To say military time correctly, voice the hour digit by digit below ten, use hundred only when the minutes are zero, prefer zero over oh, add hours if the people around you do, and name the zone letter whenever the message will travel. A day of deliberate practice fixes all five.
