If the end is earlier than the start, an overnight shift is assumed.
How the calculation works
Hours = (end − start − break). If the shift ends after midnight, we add 24h to the end time.
Frequently asked questions
How is an overnight shift counted?
Just enter the end time normally (e.g. 22:00 to 06:00) — the calculation handles the day change.
