FAQ
How do I calculate hours worked minus lunch?
Use the work-hours mode, enter your start time and end time, then enter your unpaid break in minutes. The calculator subtracts that break from the gross shift length.
Can this hours calculator handle overnight shifts?
Yes. If your end time is earlier than your start time in work-hours mode, the calculator treats it as a shift that passes midnight.
Does the result show decimal hours?
Yes. Results include a decimal-hour view, which is useful for payroll, invoicing, and timesheet entry.
What is the difference between elapsed time and work hours?
Elapsed time measures the full span between two timestamps. Work hours mode focuses on shift math and subtracts unpaid break time from the gross total.
Can I add hours to a date and time?
Yes. Use the add/subtract mode to move a base date-time forward or backward by a chosen number of hours and minutes.
Is this a payroll or overtime rules engine?
No. It is a planning calculator. It helps with time math, but overtime rules, rounding policies, and labor-law treatment can vary by employer and location.
