Formula / logic
24-hour to 12-hour: subtract 12 from any hour after 12 and label it PM (00:00 becomes 12:00 AM). 12-hour to 24-hour: add 12 to any PM hour except 12 PM.
Worked example
14:00 in 24-hour time is 2:00 PM. Conversely, 9:00 PM becomes 21:00 in 24-hour (military) time.
Frequently asked questions
What is 14:00 in regular time?
14:00 in 24-hour military time is 2:00 PM — subtract 12 from any hour past 12 to get the 12-hour equivalent.
Is midnight 00:00 or 24:00?
Military time uses 00:00 for midnight at the start of a day; 24:00 is sometimes used to mark the very end of a day, but 00:00 is standard.
Why is midnight written as 00:00?
24-hour time starts each day at 00:00 rather than 12:00, avoiding the AM/PM ambiguity around midnight and noon.
Is military time the same everywhere?
The 24-hour clock format is the same worldwide, though it's more commonly used outside the US for everyday civilian purposes.
