Calculate a shift that ends after midnight
An overnight shift crosses a calendar boundary, not a negative-time boundary. If the clock-out time is earlier than clock-in, the calculator adds one day to the end time before calculating the duration.
Enter unpaid breaks in minutes after the start and end times. The calculator deducts the break from the overnight shift total while preserving the full elapsed duration.
Worked example
A shift from 10:00 PM to 6:30 AM crosses midnight and lasts 8 hours 30 minutes. With a 30-minute unpaid meal break, worked time is 8 hours.
