Frequently Asked Questions

How do I calculate an overnight shift?

If your end time is earlier than start time (e.g., 10pm to 6am), the calculator automatically adds 24 hours to get the correct duration.

How do I convert minutes to decimal hours?

Divide minutes by 60. 30 minutes = 0.5 hours. 45 minutes = 0.75 hours. This is useful for payroll calculations.
