How Military Time Works
Military time (also known as the 24-hour clock) runs from midnight to midnight. Unlike the standard 12-hour clock which repeats the cycle of 1 to 12 twice a day (AM and PM), the 24-hour clock continues counting up after noon.
This format eliminates confusion between "morning" and "evening" hours, making it the standard for emergency services, aviation, healthcare, and the military.
Quick Conversion Rules
- Midnight to 12:59 PM: The hours are mostly the same.
Exception: 12:00 AM is 00:00. - 1:00 PM to 11:59 PM: Add 12 to the hour.
Example: 3:00 PM becomes 15:00 (3 + 12 = 15). - Say the digits: Read each hour digit before adding "hundred" or "hours" so callouts stay clear over radio or phone.
How to pronounce military time
Military time pronunciation keeps instructions unmistakable. Speak the hour digits first, then tack on the minutes and the word hours. When the minutes are 00, swap in hundred instead.
- 0800
- “Zero eight hundred hours” — morning briefings and job-site roll calls.
- 1345
- “Thirteen forty-five hours” — use the whole 24-hour number after noon, then read the minutes.
- 1700
- “Seventeen hundred hours” — late-afternoon shift change or wrap-up reminder.
- 0025
- “Zero zero twenty-five hours” — include both zeros for just-after-midnight events.
Why use the 24-hour clock?
The primary advantage is precision. In high-stakes environments like hospitals or flight control towers, mistaking 6:00 AM for 6:00 PM could be catastrophic. The 24-hour format (06:00 vs 18:00) leaves no room for ambiguity.

Frequently Asked Questions
What is "Zulu" time?
Zulu time is another name for Coordinated Universal Time (UTC). It is used by the military and aviation to ensure all operations are synchronized to a single time zone, avoiding confusion across longitudes.
Is 24:00 a valid time?
Technically, yes. 24:00 can represent the end of the day, while 00:00 represents the start of the next day. However, most digital clocks and systems rollover directly from 23:59 to 00:00.
How do I say military time out loud?
If the time is 07:00, say "zero seven hundred hours." For 15:30, say "fifteen thirty hours." If there are minutes, just say the numbers (e.g., "twenty-three forty-five" for 23:45).
Do I use a colon in military time?
It depends on the context. Standard ISO 8601 usage (14:30) uses a colon. However, traditional military usage often omits it (1430).
