The tool above does this instantly, but it's a quick calculation once you know the rule.
1. 12 AM becomes 00; keep the minutes.
2. 1 AM–11 AM: keep the hour as-is.
3. 12 PM stays 12.
4. 1 PM–11 PM: add 12 to the hour.
1. 00 becomes 12 AM.
2. 01–11: keep the hour, add AM.
3. 12 stays 12 PM.
4. 13–23: subtract 12, add PM.
Anywhere a mixed-up AM/PM could cause real problems, the 24-hour clock removes the ambiguity.
Flight plans, briefings, and logs use one unambiguous timestamp across time zones.
Medication timing and shift handoffs can't afford an AM/PM mix-up.
24/7 operations schedule around a continuous clock, not two 12-hour loops.
Most of the world outside North America uses 24-hour time by default.
Military time is the 24-hour clock. Instead of restarting the count at 1 after noon and adding AM or PM, the hours run from 00 (midnight) through 23 (11 PM), so every moment in a 24-hour day has one unique four-digit label.
If the hour is 00, it’s 12 AM. If it’s 1-11, keep the number and add AM. If it’s 12, it’s 12 PM. If it’s 13-23, subtract 12 and add PM. For example, 1445 becomes 2:45 PM.
For AM hours, 12 AM becomes 00 and the rest stay the same. For PM hours, 12 PM stays 12 and every other hour gets 12 added to it. For example, 2:45 PM becomes 1445.
Yes. “Military time” is the common US name for the 24-hour clock used by the armed forces, hospitals, airlines, and much of the world outside North America for everyday timekeeping.
0000 is midnight, the very start of the day. Some schedules use 2400 to mark the end of a day instead, but 0000 and 2400 refer to the same instant.
Hours under 10 are read as “zero” plus the digit, and on-the-hour times add “hundred” – so 0800 is “zero eight hundred.” Two-digit hours are read as the full number, like “fourteen hundred” for 1400. This is a common convention; exact phonetic style can vary by branch and context.
