Time Calculator

What is the Time Calculator – calculating time differences?

The Time Calculator calculates the difference between two times, adds or subtracts time, and converts between 12/24 hour formats. Suitable for work shifts, travel planning, and time differences.

The calculator is free, works in the browser, and does not require registration. This site offers over 200 calculators with 2026 data.

Calculation Principle

Difference = Time2 − Time1 (modulo 24 h). 12→24: PM+12 h except 12:00 = 12:00, 12:xx PM remains.

Fill in the fields with your information and press the calculate button – the result will appear immediately.

Practical Example

Work shift starts at 7:30 and ends at 16:15 → 16:15−7:30 = 8h 45min. Or New York (UTC−5) at 10:00 = another location at 18:00.

Enter your own information into the calculator to get a personal result.

• In the work shift calculator, also calculate breaks separately to reduce net working time.
