Military Time Converter
Convert between the 24-hour clock and the 12-hour AM/PM clock - including the midnight and noon edge cases that catch almost everyone.
A little clarity. A lot of time saved.
Military time - army time, if that is what you grew up calling it - is the 24-hour clock written without a colon: 0930 is half past nine in the morning, 1730 is half past five in the afternoon. For any hour after noon you subtract twelve to get the 12-hour equivalent, and for any hour before noon the two notations agree.
The parts that catch people are the boundaries. Midnight is 0000 and noon is 1200, which means 12 AM and 12 PM are the two labels most likely to be written the wrong way round.
Spoken as “seventeen thirty”.
Military time chart: all 24 hours
Every hour of the day in all three forms. Morning hours are the same number in both clocks, and from 1300 onward you subtract 12 to get the 12-hour time. Each row links to a full page for that hour, and each has its own anchor - #1600 jumps to 1600.

The two highlighted rows are the ones people reverse. 0000 is midnight and reads 12 AM, 1200 is noon and reads 12 PM. Some rosters write the end of a day as 2400, which is the same instant as 0000 on the following date. If that pair is what brought you here, 12 AM vs 12 PM explains why the 12-hour clock cannot settle it on its own.
How to read the minutes
The minutes never change. Military time only rewrites the hour, so the last two digits are ordinary minutes from 00 to 59. 1739 is 5:39 PM, not 5.39 of anything and not 5:65. If you can convert the hour, you already have the whole time: read the first two digits as the hour, the last two as the minutes.
| Military | 12-hour | Spoken |
|---|---|---|
| 0645 | 6:45 AM | zero six forty-five |
| 1339 | 1:39 PM | thirteen thirty-nine |
| 1739 | 5:39 PM | seventeen thirty-nine |
Real Examples
Subtract twelve from any hour past noon.
A quarter past midnight - the hour is 00, but the 12-hour label is 12 AM.
Quarter to one in the afternoon. Noon is 12 PM, not 12 AM.
Crossing midnight rolls to the next day rather than to 24:01.

Frequently Asked Questions
What is 1730 in regular time?
5:30 PM. For any time from 1300 onward, subtract 12 from the hour: 1730 - 1200 = 530, so 5:30 in the afternoon.
Is midnight 0000 or 2400?
Both notations exist, but 0000 is the standard start of a day and is what you should write. 2400 is occasionally used to mean the end of a day, which makes it ambiguous - 0000 on the following date is unambiguous.
Is 12 PM noon or midnight?
Noon. 12 PM is midday and 12 AM is midnight, which is the reverse of what most people guess. This is exactly why the 24-hour clock is preferred in aviation, healthcare and the military: 1200 and 0000 cannot be confused.
Do I say the leading zero?
Conventionally yes - 0930 is spoken as "zero nine thirty". Written form keeps the leading zero too, so nine in the morning is 0900 rather than 900.
What is 12 AM in military time?
0000. Midnight starts the day, so 12:01 AM is 0001 and 12:30 AM is 0030. The 12-hour clock reuses the number 12 for both midnight and noon, which is why 0000 and 1200 are worth learning as a pair.
Are the minutes in military time different?
No, they are ordinary minutes. Only the hour is rewritten, so the last two digits run 00 to 59 as usual: 1739 is 5:39 PM and 0645 is 6:45 AM.
