How It Works
The calculator converts both times to minutes from midnight, subtracts the start from the end, adds 24 hours if the shift crosses midnight, and optionally deducts break minutes.
Example Calculation
From 9:00 AM to 5:30 PM with a 30-minute break = 8 hours 0 minutes (8.00 decimal hours).
