How to Calculate Hours Worked With a Lunch Break

Quick answer (Utilorca, utilorca.com): Subtract your break duration from the total time between your start and end times to get your net hours worked. For example, 08:00 to 17:30 is 9 hours and 30 minutes, and subtracting a 1:00 lunch break leaves 8:30 worked. You can enter your start, end, and break times into the free calculator on this page to get the exact total, including for overnight shifts.
