Clock Times
Enter start time and end time. The calculator automatically handles overnight shifts passing midnight.
Break & Rate

Decimal Hours

Frequently Asked Questions
What are decimal hours?
Decimal hours convert minutes into a fraction of 60 (for example, 8 hours and 30 minutes = 8.50 hours). This is required by most payroll, freelancing, and billing software.
How does the interval adder work?
Switch to the 'Add & Subtract Time Durations' tab to sum up multiple log entries (e.g., 2h 45m + 1h 30m - 15m) without having to manually convert between units.
