How to use this calculator
The calculator finds the elapsed time between the start and end, supports shifts crossing midnight, then subtracts the unpaid break.
Formula
Worked time = End time − Start time − Break
Example
From 8:30 AM to 5:00 PM is 8 hours 30 minutes. After a 30-minute break, worked time is 8 hours.
Frequently asked questions
Does this support overnight shifts?
Yes. An end time earlier than the start time is treated as the following day.
Is this employment-law advice?
No. It performs time arithmetic only. Confirm payroll and break rules with the appropriate employer or authority.
