About Our Time Calculator

Tired of struggling with time calculations? Our easy-to-use tool handles all your time math needs, whether you're adding hours for a timesheet, subtracting durations, or scaling time values up and down.

With this calculator, you can:

  • Add two time values (e.g., 2h30m + 1h45m)
  • Subtract one time from another (e.g., 5h15m - 2h45m)
  • Multiply time by a number (e.g., 1h20m × 3)
  • Divide time by a number (e.g., 4h30m ÷ 2)
Pro Tip: For precise calculations, include milliseconds - our calculator handles all the unit conversions automatically!
