How to Convert Military Time

The rules and formulas for converting between 12-hour and 24-hour time

Military time (also called the 24-hour clock) counts hours from 0000 (midnight) to 2359 (11:59 PM). It eliminates the ambiguity of AM and PM by using a continuous count from 0 to 23 for hours.

Standard → Military

AM hours (1–11): keep the same, add leading zero
12 AM (midnight) = 0000
12 PM (noon) = 1200
PM hours (1–11): add 12 to the hour

Military → Standard

0000 = 12:00 AM (midnight)
0100–1159 = same hour AM
1200 = 12:00 PM (noon)
1300–2359: subtract 12, add PM

Examples: 3:45 PM → add 12 to 3 → 1545. 0630 → 6:30 AM. 2215 → 22 − 12 = 10 → 10:15 PM.

Key Difference: Military vs 24-Hour

Military time is written without a colon (e.g., 1430), while standard 24-hour time uses a colon (14:30). Military time is also spoken differently: "fourteen thirty hours" vs "fourteen thirty."

Who Uses Military Time

Industries and organizations that rely on the 24-hour clock

Military & Defense

All branches of the U.S. military, NATO, and most armed forces worldwide use 24-hour time to avoid AM/PM confusion in orders and operations.

Aviation & Air Traffic

Pilots, flight dispatchers, and air traffic controllers use military time (with Zulu/UTC) for all communications and flight plans globally.

Healthcare & Hospitals

Nurses, doctors, and pharmacists chart medications and procedures in 24-hour time to prevent life-threatening AM/PM dosing errors.

Emergency Services

Police, fire, and EMS dispatchers log all incidents in military time for precise, unambiguous records in reports and court proceedings.

Common Mistakes When Converting Military Time

Avoid these frequent errors when working with 24-hour time

Confusing 0000 and 2400

Both represent midnight, but 0000 is the start of a new day and 2400 is the end of the previous day. Most systems use 0000. The military uses 0000 for the beginning and 2400 for the end of a day.

Forgetting to subtract 12 for PM hours

1700 is not 7:00 AM — it is 5:00 PM (17 − 12 = 5). Always subtract 12 from hours 13 through 23 to get the standard time. A quick trick: subtract 2 from the last digit (17 → 5, 18 → 6).

Mixing up midnight and noon

12:00 AM (midnight) = 0000 military time. 12:00 PM (noon) = 1200 military time. These are the most commonly confused conversions.

Adding a colon to military time

Military time is written as four digits without a colon (1430, not 14:30). The colon format is 24-hour time, not military time. Both represent the same clock position, but the notation differs.
