Frequently asked questions
How do I calculate my work hours?
Enter your start and end time for each day you worked, then subtract any unpaid break. Shiftfy adds up the minutes and converts them to hours automatically.
How do I convert minutes to decimal hours?
Divide minutes by 60. For example, 30 minutes is 0.5 hours and 15 minutes is 0.25 hours. Shiftfy performs this conversion for every entry.
Does this calculator handle overnight shifts?
Yes. If your end time is earlier than your start time, Shiftfy treats the shift as crossing midnight and adds 24 hours.
How is overtime calculated?
Shiftfy shows any time over 40 hours in a week as overtime. Actual overtime rules vary by employer and location, so confirm with your own payroll policy.
Do I need to create an account?
No. Shiftfy works instantly without sign-up. Your entries are saved only in your own browser.
