Understanding the Time Calculator

This tool is designed for accurately adding or subtracting multiple time durations. It's particularly useful for tasks like summing up work hours from a timesheet, calculating total flight times with layovers, or analyzing data from video footage or experiments.

How to Use the Calculator

  • Enter your first time value in the hours (H), minutes (M), and seconds (S) fields.
  • To add or subtract more durations, click the "Add another time value" button.
  • For each new row, select the operation (+ Add or - Sub) you wish to perform.
  • The calculator supports decimal values in any field for high-precision calculations (e.g., 1.5 hours, or 45.75 seconds).

Interpreting the Result

The final result is displayed in a standard HH:MM:SS.ss format (Hours:Minutes:Seconds.hundredths-of-a-second). The result will be negative if the subtracted time is greater than the initial time.

For calculating your age or the time between two specific dates, our Age Calculator would be more suitable.
