Calculating the Duration from 08:30 to 17:00

Legal & practical context for 08:30–17:00
This period is the classic 9-to-5 office pattern used across corporate, financial and administrative sectors, and the basis of a standard 40-hour week. With flex-time policies, employees can shift their exact start and end. Because the shift exceeds 6 hours, labour rules require deducting a rest break (typically 30 minutes) from elapsed time to reach net work hours for payroll. Under the FLSA, remember that overtime is a weekly threshold — hours beyond 40 in a week, not beyond 8 in a day.
