About the Military Time Converter
Military Time Converter changes a time between the 12-hour clock with AM and PM and 24-hour military time. Type 3:45 PM and you get 1545, type 0830 and you get 8:30 AM. The page accepts 3pm, 3:45 pm, 15:45 or 1545 and shows the 12-hour time, the 24-hour time with a colon and the military form, plus the way military speakers say it aloud, such as fifteen forty-five hours. It is useful for work shifts, schedules, hospitals, aviation, the military and travel.

Reading military time
Military time uses the hours 00 to 23. The first two digits are the hour and the last two are the minutes. From 0100 to 1159 the hour matches the morning clock, and from 1300 onwards you subtract 12 to get the afternoon or evening hour. There is no AM or PM, so 0300 is always 3 in the morning and 1500 always 3 in the afternoon.
Quick conversion table
A few times to remember make most conversions easy: after noon, add 12 to the hour.
- 12:00 AM = 0000
- 6:00 AM = 0600
- 12:00 PM = 1200
- 6:00 PM = 1800
- 11:59 PM = 2359
Where it is used
Armed forces, aviation, emergency services, hospitals and shift work use the 24-hour clock to avoid confusing 7 AM with 7 PM. Timetables for trains and flights in many countries also use it. If you work abroad, it helps to read it fluently.
