Military Time Calculator
Switch between standard (12-hour) time and military (24-hour) time, and find the hours between a start and end time written in military time.
How to convert standard time to military time
- AM times: keep the hour and show it with two digits. 8:30 AM is 0830. The exception is midnight: 12:00 AM is 0000, and 12:15 AM is 0015.
- PM times: add 12 to the hour. 5:30 PM is 17 + 30 = 1730. The exception is noon: 12:00 PM stays 1200, and 12:45 PM is 1245.
How to convert military time to standard time
- 0000 to 0059: the hour becomes 12 and it is AM: 0015 is 12:15 AM.
- 0100 to 1159: same hour, AM: 0830 is 8:30 AM.
- 1200 to 1259: same hour, PM: 1245 is 12:45 PM.
- 1300 to 2359: subtract 12 from the hour, PM: 1730 is 5:30 PM.
Hours worked: a shift from 0800 to 1630 is 8 hours 30 minutes. With a 30-minute unpaid break, that is 8 hours (8.00 decimal hours). A night shift from 2200 to 0600 is 8 hours, because the end time is on the next day.

Military time is simply the 24-hour clock written without a colon. Many time clocks, hospitals, airlines and emergency services use it because there is no AM or PM to mix up. To add up a whole week from in and out times, use the time card calculator, or add shift lengths with the time calculator. To change a total into decimal hours for payroll, use the hours to decimal calculator.

0000 (written 00:00). Midnight at the start of a day is 0000, and 12:15 AM is 0015. Some people write 2400 for midnight at the end of a day; this calculator treats 2400 as midnight.

How do I calculate hours worked in military time?
Subtract the start time from the end time. If the end is earlier than the start, the shift runs past midnight, so add 24 hours to the end time first. 2200 to 0600 is 8 hours. Take off any unpaid break.
Is military time the same as 24-hour time?
Yes. Military time is the 24-hour clock written without a colon and with four digits, for example 0730 instead of 7:30.
