What Is Military Time?
Military time is the 24-hour clock — hours run from 0000 (midnight) to 2359 (11:59 PM). No AM or PM. No ambiguity about whether "6 o'clock" means morning or evening. When a nurse charts medication at 1430, everyone knows that's 2:30 in the afternoon.
The format is always four digits. The first two are the hour (00–23), the last two are the minutes (00–59). That's the whole system. What trips people up is hours 13–23, which have no 12-hour equivalent — you just subtract 12 to get the PM hour.
Despite the name, military time isn't exclusive to the military. Hospitals, airlines, railroads, emergency services, and most of Europe use the 24-hour clock as standard. If you've ever read a European train schedule, you've read military time.
📊 The 24-hour clock is the international standard (ISO 8601) and is used officially in over 100 countries. The 12-hour AM/PM system is primarily used in the United States, Canada, Australia, and parts of Latin America. — NIST Time & Frequency
How to Convert Military Time to Regular Time
For hours 0100–1159 (AM times)
Drop the leading zero and add AM. 0800 → 8:00 AM. 1100 → 11:00 AM. Minutes stay unchanged — 0830 → 8:30 AM, 0945 → 9:45 AM.
0930 → 9:30 AM · 1115 → 11:15 AM
For hours 1300–2359 (PM times)
Subtract 1200 from the hour, add PM. 1300 → 1:00 PM. 1800 → 6:00 PM. 2145 → 9:45 PM.
1300 − 1200 = 1:00 PM · 2030 − 1200 = 8:30 PM
Special cases: 0000 and 1200
0000 = 12:00 AM (midnight). 1200 = 12:00 PM (noon). These two catch people because the subtraction rule breaks — 1200 minus 1200 is 0, not 12. Just memorize them: 0000 is midnight, 1200 is noon.
How to Convert Regular Time to Military Time
For AM times: add a leading zero if the hour is single-digit, drop the AM, write minutes as-is. 9:30 AM → 0930. 11:15 AM → 1115. 12:00 AM (midnight) → 0000.
For PM times: add 1200 to the hour (except 12:00 PM). 1:00 PM → 1 + 12 = 13 → 1300. 6:45 PM → 6 + 12 = 18 → 1845. 12:00 PM (noon) → 1200.
Quick rule: AM hours → pad to 4 digits, remove colon. PM hours → add 12 to the hour, remove colon. Midnight = 0000. Noon = 1200.
Who Uses Military Time?
The short list: the US military (where the name comes from), hospitals and nursing staff, aviation (all flight plans use UTC in 24-hour format), emergency services (police, fire, EMS), public transportation schedules, and most countries outside North America.
In healthcare, the 12-hour clock is genuinely dangerous. "Give medication at 6" is ambiguous — 6 AM or 6 PM? At a 12-hour interval, that's the difference between a correct dose and a double dose. Hospitals in the US switched to 24-hour charting specifically to eliminate that ambiguity.
Aviation uses Zulu time (UTC in 24-hour format). A flight departure logged at "1430Z" is 2:30 PM UTC, regardless of which time zone the airport is in. Same principle — remove ambiguity, prevent errors.
