Frequently Asked Questions
How do I calculate my work hours?
Enter your start time and end time for each day, plus any unpaid break time. The calculator subtracts the break and gives you the exact hours:minutes worked that day. The weekly total automatically accumulates.
Does it handle overnight shifts?
Yes. If your end time is earlier than your start time (e.g., start 22:00, end 06:00), the calculator correctly handles it as an overnight shift.
How is overtime calculated?
Overtime is calculated after the weekly threshold (default 40 hours). Hours worked beyond the threshold are counted as overtime. You can customize the threshold and overtime rate.
Can I calculate pay with this tool?
Yes. Enter your hourly rate and the tool will compute regular pay, overtime pay (at the rate you specify), and gross weekly pay. Supports multiple currencies.
