How to Use the Workday Calculator

  1. Enter the start time of your workday in the "Start Time" field using the format HH:MM (e.g., 09:00 for 9:00 AM).
  2. Enter the end time of your workday in the "End Time" field using the format HH:MM (e.g., 17:30 for 5:30 PM).
  3. Enter the total break duration in minutes in the "Break Duration" field. This includes all breaks such as lunch breaks, short breaks, etc.
  4. Click the "Calculate" button to calculate the total work hours.
  5. The results will display the total work hours and total minutes worked.

Example

If you start work at 09:00 AM and finish at 5:30 PM with a 1-hour break, the calculator will calculate:

  • Work hours: 7.50 hours (8 hours - 1 hour break)
  • Work minutes: 450 minutes

Working Principle

The calculator works by:

  1. Converting both start and end times to minutes since midnight.
  2. Subtracting the break duration from the total time worked.
  3. Converting the result back to hours and minutes for display.

Important Notes

  • Ensure that the end time is after the start time for accurate results.
  • The break duration should be entered in whole minutes.
  • If the end time is entered before the start time, the calculator will display "Invalid" to indicate an error.
