Military time converter

Goes beyond the chart: shift length across midnight with unpaid breaks, adding and subtracting time, and US time-zone and Zulu conversion that follows daylight saving for the date you pick.

In short

Military time numbers the day from 0000 to 2359 with no AM or PM. To convert, keep 0000 to 1159 as AM, 1200 to 1259 as PM, and subtract 12 from 1300 to 2359 for PM. So 1800 is 6:00 PM and 2200 is 10:00 PM. Type any time below to convert it and hear how to say it.

What do you need?

Convert

Type military, clock or 12-hour time. Noon and midnight work too.

Check anything critical. Time-zone answers come from your browser’s time-zone data, and shift hours are plain arithmetic on the times you type. Your employer’s rounding and break rules are not applied. For aviation, military or legal scheduling, confirm with an authoritative source.

Worked out from the times entered. Time-zone results depend on the rules in the browser’s time-zone database for the date chosen.

How to use it

  1. On Convert, type a time such as 1830, 18:30 or 6:30 pm.
  2. On Shift hours, enter a start time, an end time and any unpaid break to get paid hours, even across midnight.
  3. On Add or subtract, enter a starting time and the hours and minutes to move it.
  4. On Time zones, enter a time, a date and two zones to convert, including Zulu (UTC).
  5. Copy the result, or download the sheet, which includes the full 24-hour chart.

How it calculates

Every time is turned into minutes after midnight, so a shift that ends earlier than it starts has 24 hours added to its end. Adding and subtracting works the same way and reports how many days the result moves. Time-zone answers are not hard-coded: the tool asks your browser for the IANA rules for the date you choose, so daylight saving is handled for you.

For example, 6:30 pm is 1830, said “eighteen thirty hours”. A night shift from 2200 to 0600 crosses midnight, so 24 hours are added to the end: that is 8 hours, and with a 30-minute unpaid break the paid time is 7.5 hours. The times are made up; yours come from what you type.

Who should use it

  • Anyone reading a 24-hour schedule, roster or timetable
  • Shift workers and managers working out paid hours for a night shift
  • People coordinating across US time zones or with Zulu time

Who should not use this

  • Anyone doing aviation, military or legal scheduling that must match an authoritative source
  • Employers who need payroll rounding and break rules applied; this does plain arithmetic on the times you type
  • Anyone needing seconds or single-letter military zone designations other than Z

Limitations

  • Shift length is calculated for one turn of the clock, so a duty period longer than 24 hours needs to be split.
  • Times are handled to the minute, not the second.
  • Time-zone results depend on the rules in your browser’s IANA data, which can change if governments change their clocks.
  • A time inside a daylight-saving gap or overlap is flagged, and the earlier occurrence is used for an overlap.
  • Nothing is uploaded or stored on a server. Clearing your browser data also removes the saved profile.

Common questions

What is 17:00 military time?
17:00 is 5:00 PM. Subtract 12 from 17 to get 5 and add PM. Spoken, it is “seventeen hundred hours”.
What is 22:00 military time?
22:00 is 10:00 PM. Subtract 12 from 22. Spoken, it is “twenty-two hundred hours”.
What is 14:00 military time in EST?
14:00 is 2:00 PM. In Eastern Standard Time it is 1400 EST, which equals 1900Z because EST is five hours behind UTC. During daylight saving time the same reading is EDT and equals 1800Z.
How do I convert military time to standard time?
For 0100 to 1159, drop the leading zero and add AM. For 1200 to 1259, keep the hour and add PM. For 1300 to 2359, subtract 12 from the hour and add PM. 0000 to 0059 is 12 AM.
Is midnight 0000 or 2400?
Most sources write 0000 for the start of a day. Some write 2400 for the end of the same day, which is the same instant as 0000 on the next date. Using 0001 or 2359 avoids the ambiguity.
How do you calculate hours worked from military time?
Convert both times to minutes after midnight. If the end is earlier than the start, add 1,440 minutes to the end. Subtract the start, then any unpaid break. For 2200 to 0600 with a 30-minute break, the result is 7.5 hours.
What does the Z in 1830Z mean?
Z stands for Zulu time, which is UTC. 1830Z is 18:30 UTC. It does not change with daylight saving time.
