How to use this result
Choose next day for a shift such as 7 p.m. to 7 a.m. Without that setting, the end time falls before the start. Subtract an unpaid meal period only once.
This is a wall-clock duration tool. It does not know the date or time zone, so overnight daylight saving transitions need an elapsed-time check using your actual timestamps.
The formula
Worked example
Using the example inputs loaded above:
11.5 hr
Paid working time.
Common questions
Can I calculate a 24-hour shift?
Yes. Use matching start and end times and select next day. Shifts longer than 24 hours are outside this tool.
Will this round to a time-clock increment?
No. It retains the entered minutes. The decimal display is rounded only for readability.
Assumptions & references
Amounts use USD. Results are planning estimates using your entries, with dollars rounded only for display. Each tool covers the model described here; it does not determine payroll or tax obligations. Read the calculation methodology.
