Hours Calculator Frequently Asked Questions

What time formats are supported?

Our calculator supports HH:MM format (like 8:30) and decimal hours (like 8.5). You can mix formats in the same calculation, and the tool automatically converts between them for accurate results.

How do I calculate overtime hours?

Enter your total hours worked and subtract your regular hours (typically 40 per week). The calculator will show the difference, which represents your overtime hours.

Can I subtract time periods?

Yes! Switch the operation mode to 'Subtract' to calculate time differences. This is useful for finding break durations, time between shifts, or project duration calculations.
