How to use Hours Calculator
Enter your start time, end time, and break duration in minutes. The Hours Calculator shows total time, break time, net working time, and decimal hours (useful for timesheet calculations).
The calculator handles overnight shifts — if end time is earlier than start time, it assumes the shift crosses midnight and adds 24 hours accordingly.
Overnight shifts
If your end time is before your start time, the calculator automatically adds 24 hours to account for midnight crossings.
Break deduction
Enter break duration in minutes (e.g., 30 for lunch). The calculator deducts it from total time to show net hours worked.
