Working Hours Per Day
Compute actual working hours in a day after subtracting breaks.
About Working Hours Per Day
The start and end are converted to minutes, the break is removed, and the result converts to hours and then to a weekly total. Breaks are not paid work, so subtracting them gives the real capacity for scheduling and payroll estimates.
Formula
Working Hours Per Day
Working minutes = (end - start, plus 24 h if overnight) - break; weekly = daily x days worked
- overnight
- An end earlier than start means the shift crosses midnight
