Questions and answers

How do I turn minutes into decimal hours?

Divide the minutes by 60. For example 7:45 is 7 + 45/60 = 7.75 hours. The calculator shows both formats, so you can copy the one your timesheet uses.

How do I calculate hours worked with a lunch break?

In the second part, enter the start time, the end time and the length of the break. For example 08:00 to 17:30 with a 1:00 break is 8:30 hours worked.

What if the shift ends after midnight?

Enter the times as they are, for example 22:00 to 06:00. When the end is earlier than the start, the calculator counts it as the next day.
