Military time converter
Type 3 or 4 digits, like 0930, 930, or 1700. A colon is fine too.
How to read military time
Military time is a 24-hour way of writing the time with four digits and no colon. It counts the hours from 00 to 23, so there is no AM or PM. These rules cover every case:
- Before noon (AM): drop the colon and make it four digits. 9:30 AM is 0930.
- After noon (PM): add 12 to the hour. 4:24 PM is 4 + 12 = 16, so 1624.
- Noon: 12:00 PM is 1200. Don't add 12 to it.
- Midnight: 12:00 AM is 0000. 12:45 AM is 0045.
- Going back to standard: if the hour is 13 or more, subtract 12 and use PM. 1915 is 7:15 PM.
Not sure which of 12 AM and 12 PM is midnight? 12 AM vs 12 PM explained also covers which day midnight belongs to.

The 24-hour clock
The 24-hour clock numbers the hours of the day from 00 to 23, starting at midnight. There's no AM or PM. After 12:59 in the afternoon the clock keeps counting to 13:00, and it reaches 23:59 one minute before the next midnight. The converter above shows the 24-hour form (HH:MM) next to every answer, so you can copy whichever one you need.
How to read it
The first two digits are the hour and the last two are the minutes. Hours 00 through 11 are the morning, 12 is the noon hour, and 13 through 23 are the afternoon and evening. So 08:15 is 8:15 in the morning and 20:15 is 8:15 at night. You can type times like 19:30 straight into the online alarm clock too.
To switch between 24-hour and 12-hour time, use the rules under How to read military time above and keep the colon: 19:00 is 7:00 PM, just like 1900.
Colon or no colon
Military time uses the same numbers as the 24-hour clock. The difference is the colon and how it is said:
| Format | Written | Said as |
|---|---|---|
| 24-hour clock | 17:00 | seventeen hundred, or five o'clock |
| Military time | 1700 | seventeen hundred hours |
00:00 or 24:00?
Midnight is normally written 00:00, the start of a new day. Some schedules write 24:00, or 2400, for the end of a day instead. The US National Institute of Standards and Technology describes that convention, 0000 for midnight at the start of a day and 2400 for the end, and notes that 12 a.m. and 12 p.m. are ambiguous and shouldn't be used. NIST also suggests 11:59 p.m. or 12:01 a.m. for deadlines, which leaves no doubt about the day. There's more on that in 12 AM vs 12 PM explained.
Military time questions
What time is 2000 in military time?
2000 is 8:00 PM. Subtract 12 from any hour of 13 or more to get the PM hour: 20 − 12 = 8.
What time is 1830 in military time?
1830 is 6:30 PM. The hour is 18, and 18 − 12 = 6, so it's 6:30 in the evening.
What is 5 PM in military time?
5 PM is 1700. Add 12 to any PM hour from 1 to 11: 5 + 12 = 17, written as 1700 and said as seventeen hundred hours.
What time is 1600 in military time?
1600 is 4:00 PM, because 16 − 12 = 4.
Is midnight 0000 or 2400?
Midnight is normally written 0000, the start of the new day. Some schedules use 2400 to mark the end of a day, so this converter accepts 2400 and shows it as 0000 on the next day. The minute after midnight is 0001, and 12:30 AM is 0030.
Is military time the same as the 24-hour clock?
The hours are the same. The difference is in how it's written and said. The 24-hour clock usually has a colon, as in 17:00, while military time drops the colon and adds hours when spoken, as in seventeen hundred hours.
How do you say military time out loud?
On the hour, say the hour followed by hundred hours, so 1700 is seventeen hundred hours and 0600 is zero six hundred hours. Otherwise say the two pairs of digits, so 1430 is fourteen thirty hours. Habits differ between services and countries, and some people say oh instead of zero.

The military time converter on TimerCalculator.com was built by Cedrick Reese. The converter and the chart run on one function, so the chart can't drift from the answers. It was set up this way after a hand-typed chart on another converter site turned out to list 1830 as 2:30 PM. For this version, an automated browser test fed 0000, 0045, 1200, 1215, 1830, 2359, and 2400 into the converter, then checked that the chart rows for 0000, 1200, and 1830 showed the same answers. Military time rules don't change, so there's no outside data to keep current.
