Military Time Converter
24-hour to 12-hour, with midnight and noon right.
Convert Military Time. 24-hour to 12-hour, with midnight and noon right. Daylight saving cannot shift the answer.
As HH:MM. Midnight is 00:00.
12-hour clock
1:45 PM
13:45 · 1:45 PM
Midnight and noon are where this conversion goes wrong, and they go wrong in opposite directions. Midnight is 00:00 and 12:00 AM — not 0:00 AM, which does not exist. Noon is 12:00 and 12:00 PM — not 0:00 PM. The 12-hour clock has no zero hour at all, which is why 12 appears at both ends and why the hour after 12:59 PM is 1:00 PM rather than 13:00 PM.
How the Military Time Converter works
Convert between the 24-hour and 12-hour clocks in either direction. Midnight and noon are where these conversions break, and they break in opposite directions — 00:00 is 12:00 AM and 12:00 is 12:00 PM, not 0:00 of either.

Frequently asked questions
How do I convert military time to standard time?
For hours under 12, keep the number and add AM. For 13 and above, subtract 12 and add PM. The exceptions are 00:00, which is 12:00 AM, and 12:00, which is 12:00 PM.
Why is midnight 12:00 AM and not 0:00 AM?
Because the 12-hour clock has no zero hour. It runs 12, 1, 2 … 11 and then starts again, so 12 appears at both ends of the cycle. That is also why 12:59 PM is followed by 1:00 PM.
Is noon 12 AM or 12 PM?
12 PM. AM means ante meridiem, before midday, and PM means post meridiem, after it. Noon is the meridiem itself, so strictly it is neither — the convention assigns it to PM, and midnight to AM.
Why does the military use the 24-hour clock?
Because it removes the ambiguity entirely. There is exactly one 13:00 in a day and no need to say which, which matters when a misread order costs more than a missed appointment.
