Frequently Asked Questions
Add 8 hours to your start time, then add the total break duration (in minutes). For example, start at 9:00 AM with a 30-minute break gives an end time of 5:30 PM.
The calculator automatically sets the break at the midpoint of the shift (4 hours after start) for convenience.
This calculator assumes breaks are unpaid, so total paid hours = 8 hours minus break duration. Adjust if your breaks are paid.
