Common questions
Hours calculator answers.
How do I convert minutes to decimal hours?
Divide the minutes by 60, then add the whole hours. For example, 45 minutes divided by 60 is 0.75, so 8 hours 45 minutes is 8.75 hours.
Does a 30-minute unpaid break count as work time?
This calculator subtracts the unpaid break you enter from the elapsed shift. Whether a break is paid depends on the employer and applicable rules.
Can I calculate an overnight shift?
Yes. If the end time is earlier than the start time, the calculator treats the shift as ending the following day.
Should payroll round decimal hours?
Use the rounding and timekeeping rules that apply to your workplace. This tool shows two decimal places for convenience and does not determine payroll compliance.
