Frequently Asked Questions
How do I calculate a shift that crosses midnight?
Choose the cross-midnight option. The tool adds 24 hours to the end time before subtracting, so a shift from 22:00 to 06:00 correctly gives 8 hours instead of a negative number.
Why show decimal hours?
Payroll and timesheet systems usually need decimal hours: 8 hours 30 minutes is 8.5 hours. Multiply decimal hours by an hourly rate to get gross pay for the shift.
Should breaks be deducted?
This tool measures elapsed time between the two clock times. If you take unpaid breaks, run the calculation for each work segment separately and add the durations together.
Is the Time Duration Calculator free, and is my data private?
Yes. It is completely free and every calculation runs locally in your browser, so the numbers and dates you enter are never uploaded, stored, or shared with anyone.
