24-hour, 12-hour, and military — what’s the difference?
The 12-hour clock splits the day into two halves labelled AM and PM, which is how most people say the time. The 24-hour clock runs 00:00 to 23:59 with no AM/PM, so a time can never be misread — which is why it’s standard in hospitals, transport, and most of the world. Military time is the same 24-hour clock written without a colon (1430) and spoken distinctly (“fourteen thirty”).
The one place all three trip people up is 12: 12:00 AM is midnight (00:00) and 12:00 PM is noon (12:00). If you also need to calculate with times rather than just reformat them, see the time calculators, and for a printable reference, the 24-hour clock chart.
Frequently asked questions
Is 24-hour time the same as military time?
Almost. Both use the 0–23 hour clock. Military time is usually written without a colon and spoken differently, but the underlying value is identical — 14:30 and 1430 are the same time.
What is 1400 in 12-hour time?
1400 is 2:00 PM. For any hour from 13 to 23, subtract 12 and add PM.
Is midnight 00:00 or 24:00?
Midnight at the start of a day is 00:00. Some timetables write 24:00 to mean midnight at the end of a day, but 00:00 the next day is the same moment.
