How do you convert military time?
Military time runs the day from 0000 to 2359 in one continuous count, with no AM or PM. The rule fits in two lines:
- From 0000 to 1159 the hour reads as it stands, so 0930 is 9:30 AM.
- From 1300 to 2359 you subtract 12, so 1730 becomes 5:30 PM and 2145 becomes 9:45 PM.
Going back the other way, add 12 to any PM hour except 12 PM itself, so 5:30 PM turns into 1730. Morning hours only pick up a leading zero, which makes 8:05 AM into 0805.
How do you handle midnight and noon?
Noon is simply 1200. Midnight has two correct spellings: 0000 opens a day and 2400 closes the one before it. A patrol ending Tuesday at 2400 stops at the exact moment Wednesday 0000 begins. The 12-hour clock maps 12 AM to midnight and 12 PM to noon, a pairing confusing enough that hospitals often write 2359 or 0001 on orders to kill any doubt.

The full hour-by-hour list lives on the military time chart.
How do you say military time out loud?
Whole hours take the word hundred, so 0700 is zero seven hundred hours and 1300 is thirteen hundred hours. Hours below ten keep the spoken zero. With minutes, read the two pairs in order, so 1730 is seventeen thirty hours and 0905 is zero nine zero five hours. US military usage keeps the word hours, while aviation and NATO traffic often drop it and may add Zulu for UTC, as in 1730Z.
Who uses the 24-hour clock?
Well beyond the armed forces: hospitals for medication schedules, airlines and railways for timetables, emergency dispatch, ship logs, and most of the world in everyday writing. If your time cards come in 24-hour notation, pair this converter with the hours calculator to total a shift.
Why do hospitals and airlines use the 24-hour clock?
Because one ambiguous digit can cost a dose or a flight. Three failure modes vanish with 24-hour notation:
- Medication timing: an order for 9:00 could mean morning or evening. Written 0900 or 2100, a 12-hour dosing error becomes impossible, which is why medication records are charted from 0000 to 2359.
- The midnight boundary: a 12:00 AM Tuesday departure sits at the very start of Tuesday, and travelers routinely read it as Tuesday night. Airlines print 0010 or 2350 instead and tend to avoid scheduling anything at 0000.
- Sorting: times written 0000 to 2359 line up correctly as plain text, so crew rosters and nurse handover sheets stay chronological without any AM or PM parsing.
Aviation adds one more layer, since schedules are coordinated in UTC and marked with a Z suffix, so 1730Z names the same instant in every time zone the flight crosses.
