How military time works
Military time is the 24-hour clock written without a colon, always as four
digits. Midnight is 0000 and the day runs through to
2359, so there is no am/pm and no ambiguity about which
“seven o'clock” you mean.
Converting in your head
- Before noon: the hours are the same. 9:15 am is
0915. - After noon: add 12 to the hour. 1:45 pm is
1345. - Going back: if the hour is 13 or more, subtract 12 and add “pm”.
Midnight and noon
These are the two that catch people out. 0000 is midnight at the
start of the day and 1200 is noon — so 12 am is
0000, not 1200. Some organisations write midnight as
2400 to mean the end of a day rather than the beginning of the next
one.
Saying it out loud
Hours below ten get a spoken “zero”, so 0730 is
“zero seven thirty”. An exact hour uses “hundred”:
1400 is “fourteen hundred”. A trailing
Z means the time is in UTC, spoken as “Zulu”.
