- 2400 is sometimes used for midnight at the end of a day (e.g. "open until 2400"). It is the same moment as 0000 the next day.

Conversion rules in one minute
| 12-hour time | Rule | Example |
|---|---|---|
| 12:00 AM to 12:59 AM | Hour becomes 00 | 12:15 AM → 0015 |
| 1:00 AM to 11:59 AM | Keep the hour, add a leading zero | 6:30 AM → 0630 |
| 12:00 PM to 12:59 PM | Hour stays 12 | 12:45 PM → 1245 |
| 1:00 PM to 11:59 PM | Add 12 to the hour | 9:10 PM → 2110 |
Going the other way, subtract 12 from any hour of 13 or more and add PM. Hour 00 becomes 12 AM and hour 12 becomes 12 PM. Minutes and seconds never change.
Where 24-hour time is used
- Military and emergency services, where an AM/PM mix-up could be dangerous.
- Hospitals and nursing, for medication schedules and charting.
- Aviation, usually in UTC ("Zulu" time), for example 1430Z.
- Public transport timetables and most countries outside the US, Canada, Australia and a few others, where 24-hour time is the everyday standard in writing.
- Computing: the ISO 8601 standard writes times as hh:mm:ss in 24-hour form, for example 2026-10-19T19:45:00.
Speaking military time
Each time is read as hours then minutes, followed by "hours". Whole hours use "hundred": 0600 is "zero six hundred" and 2000 is "twenty hundred". Minutes below 10 are read with "zero": 1405 is "fourteen zero five". Some speakers say "oh" instead of "zero" (for example "oh six hundred"), and in casual use the word "hours" is often dropped. On the radio, aviators and the military often read each digit separately, such as "one niner four five".
The phonetic word "niner" is used for 9 in radio speech to avoid confusion with the German "nein". Time zones are added with a letter, such as Z (Zulu, UTC) or R (Romeo, UTC−5).

Frequently asked questions
How do I convert PM times to military time?
Add 12 to the hour for any time from 1:00 PM to 11:59 PM and drop the colon. For example 7:45 PM becomes 19:45, or 1945 in military time. Noon (12 PM) stays 1200.
How do I convert military time to standard time?
If the hour is 13 or more, subtract 12 and add PM: 1945 becomes 7:45 PM. Hours 01 to 11 are AM, 12 is PM (noon) and 00 is 12 AM (midnight): 0030 is 12:30 AM.
Is midnight 0000 or 2400?
Midnight at the start of a day is 0000. Some schedules use 2400 to mean midnight at the end of a day, for example "open 0800 to 2400". Both refer to the same moment; most clocks show 00:00.
How do you say military time out loud?
Say the hours and minutes as two numbers and add "hours". 1945 is "nineteen forty-five hours", 0700 is "zero seven hundred hours" and 1305 is "thirteen zero five hours". A leading zero is usually spoken as "zero".
Is 12:00 AM midnight or noon?
12:00 AM is midnight (0000) and 12:00 PM is noon (1200). Because this is easy to mix up, schedules in medicine, aviation and the military use 24-hour time.
What is the difference between 24-hour time and military time?
They are the same clock. Military style usually drops the colon (1945) and is spoken with "hours", while civilian 24-hour time is written with a colon (19:45).
