Frequently asked questions
Does it handle overnight shifts?

Yes. Enter the break length in minutes and the total is reduced automatically so your net working time is accurate.
Does it support multiple shifts?
Yes. The work-hours mode totals multiple shift blocks, which is useful for payroll, planning, and scheduling.
Is it accurate?
