Time Duration Calculator — Hours Between Times
Work out hours and minutes between a start and end time, minus breaks.
Calculates hours worked between two times, minus your break. The decimal hours figure (e.g. 7.50) is handy for timesheets and payroll. Runs in your browser.
Enter a start and end time to get the duration in hours and minutes, with a break deducted if you like. It handles overnight shifts (end time on the next day) and shows decimal hours — for example 7.50 — which is what payroll and timesheets usually need. For adding up several shifts, use the Hours Calculator. Runs entirely in your browser.
How to use the Time Duration Calculator
- Enter the start and end times.
- Set any break in minutes and toggle overnight if the shift crosses midnight.
- Read the net duration and decimal hours.
Frequently asked questions
Can it handle overnight shifts?
Yes. Tick the overnight option and an end time earlier than the start is treated as the next day, so a 22:00-06:00 shift comes out as 8 hours.
What are decimal hours?
Hours expressed as a decimal — 7 hours 30 minutes becomes 7.50. Payroll systems and invoices usually expect this format.
How do I add up several time periods?
Use the Hours Calculator, which sums multiple start/end rows. This tool focuses on a single start-to-end duration.
