Formula and calculation method
Elapsed minutes = end − start, adding 1440 for an overnight shift. Paid minutes = elapsed − break.
One shift shorter than 24 hours. Equal times mean zero duration. No overtime or daylight-saving adjustment.

Factors affecting your result
One shift shorter than 24 hours. Equal times mean zero duration. No overtime or daylight-saving adjustment.
Changing start time changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
