Working Hours Calculator
Calculate hours worked between clock-in and clock-out times.
What is Work Hours?
A timesheet helper: enter clock-in, clock-out, and break length to get net hours worked, plus a running weekly total across multiple days.
How it works
Durations are computed in minutes with overnight handling, breaks subtracted, and the week's total accumulated and formatted as h:mm.

Examples
Timesheet entry
Enter 09:00–12:00 and 13:00–17:00 to total 7 hours — with lunch excluded automatically so the day's billed time is correct.
Common mistakes
Forgetting breaks
Raw start-to-end time overstates work. Enter intervals exactly as clocked, or subtract breaks explicitly.
Frequently asked questions
Can I total a whole week?
Yes — add daily intervals and the week's total appears in hours and minutes.
Does it handle overnight shifts?
Yes — an interval ending before it starts is treated as crossing midnight.
Can I export the summary?
Copy the totals or per-day breakdown for pasting into a timesheet or spreadsheet.
