Hours Calculator FAQ

How do I calculate hours between two times across midnight?

Enter the start time and end time as usual. If the end time is earlier than the start time, the calculator treats it as the next day, so a shift from 10 PM to 6 AM correctly returns 8 hours.

What are decimal hours and why do payroll systems use them?

Decimal hours express minutes as a fraction of an hour, so 7 hours 30 minutes becomes 7.5 hours. Payroll and billing systems use decimal hours because they multiply cleanly with hourly rates.

Can I subtract break time from worked hours?

Yes. Calculate the gross hours between clock-in and clock-out first, then subtract the break duration in the time subtraction mode to get net working hours.
