About the military time converter
This tool converts between 12-hour time (with AM/PM) and 24-hour military time in both directions, live as you type — for example 1:00 PM converts to 1300, and 2130 converts to 9:30 PM.
24-hour "military" time avoids the AM/PM ambiguity of 12-hour clocks, which is why it is standard in the military, healthcare, aviation, and much of the world outside a few English-speaking countries. This converter switches between the two formats instantly and in either direction, supporting both a friendly hour/minute + AM/PM picker and raw text entry (paste something like "2130" or "9:30 PM" and it is parsed automatically).
Common military time conversions
| Military (24h) | 12-hour | Note |
|---|---|---|
| 0000 | 12:00 AM | Midnight |
| 1200 | 12:00 PM | Noon |
| 1300 | 1:00 PM | One hour after noon |
| 2359 | 11:59 PM | Last minute of the day |
When to use it
- Reading a schedule, timetable or log file written in 24-hour time.
- Converting a flight, train or hospital shift time into a more familiar 12-hour format.
- Writing documentation or forms that need to state a time unambiguously.
How to use it
- Enter a time using the hour/minute + AM/PM picker, or type a raw value like "2130" or "9:30 PM" into the text field.
- Read the converted equivalent instantly in the other format.
- Check the reference table for common conversions like noon and midnight.
Tips
- Midnight is always 0000 in 24-hour time, never 2400 — and noon is 1200, not 0000, which trips people up most often.
- When in doubt on a form, 24-hour time removes any AM/PM ambiguity entirely.
FAQ
What is military time?
24-hour time, running from 0000 (midnight) to 2359 (11:59 PM), with no AM/PM needed since each hour of the day has a unique number.
Is noon 1200 or 0000 in military time?
Noon is 1200. Midnight is 0000. This is the single most common point of confusion when converting.
Can I type a time directly instead of using the picker?
Yes — the text field accepts formats like "2130" or "9:30 PM" and parses them automatically.
What is 1400 in regular time?
2:00 PM. For any 24-hour time from 1300 onwards, subtract 12 from the hours to get the PM equivalent, so 1400 becomes 2 PM, 1830 becomes 6:30 PM, and 2100 becomes 9 PM.
Why is 24-hour time used in hospitals and the military?
It removes AM/PM ambiguity. On a 24-hour clock every time in a day has exactly one representation, which matters when a mistaken reading on a medication chart, flight plan or shift roster has real consequences.
Is midnight 0000 or 2400?
Both notations exist. 0000 is the standard start of a day, and 2400 is sometimes used to mark the end of the previous day. They point at the same instant, which is why schedules usually prefer 2359 or 0001 to avoid the ambiguity entirely.
How do you say military time out loud?
Four digits read as hundreds: 1400 is "fourteen hundred", 0700 is "zero seven hundred". Times with minutes are read straight through, so 1435 is "fourteen thirty-five".
How do I convert 12 hour time to military time?
For PM times add 12 to the hour (3:15 PM becomes 1515); for AM times keep the hour and add a leading zero (9:05 AM becomes 0905). Midnight is 0000 and noon is 1200. The converter above does it instantly, both ways between 12 hour and 24 hour time.
