Military Time Card Calculator

How to use the military time calculator

1. Enter each day's punches on the 24-hour clock: 0900, 1730, 2215. A colon is optional, so 9:00 and 17:30 also work.
2. For overnight shifts, just type the real out time — 2200 to 0600 totals 8 hours with no manual splitting.
3. Set a break in minutes per day, or apply one break to every day at once.
4. Optionally enable rounding and overtime, and add an hourly rate for a pay breakdown.
5. Print a clean timesheet or export to CSV — free and without an account.

Reading the 24-hour clock

Military time removes the AM/PM ambiguity by numbering the hours 0 through 23. Midnight is 0000, noon is 1200, and the evening hours keep counting up: 6 PM is 1800, 11 PM is 2300. Minutes never change — they are still 00 to 59. To convert an afternoon time back to a 12-hour clock, subtract 12 from the hour: 1900 minus 12 is 7, so 1900 is 7:00 PM.

Why 24-hour time is easier for time cards

Payroll errors often come from an AM/PM mix-up — an 8 that should have been a 20, a shift logged twelve hours off. The 24-hour clock makes every punch unambiguous, which is why hospitals, transit, manufacturing, the military, and much of the world outside North America use it on timesheets. This calculator defaults to 24-hour entry but still accepts a stray 5pm if that is how a punch was recorded.

Breaks, rounding, and overtime work the same

Everything the weekly calculator does applies here. Breaks in minutes are subtracted from each shift, punch rounding follows the 7-minute rule when you select 15 minutes, and overtime is measured against your weekly threshold. The only difference is the clock notation on input.

Converting the total for payroll

The result is shown in hh:mm and decimal. If your payroll system wants decimal hours, copy the decimal figure directly, or use the decimal hours converter for a full lookup chart.
