📐 How the Work Hours Formula Works
Under the hood, the calculator follows these steps:
- Converts start and end times into minutes since midnight
- Calculates the difference between them
- Adjusts if the shift goes overnight (end time is earlier than start time)
- Subtracts break time (if provided)
- Converts the final time into hours and minutes
🧮 Example
You work a shift from 9:00 AM to 5:30 PM, and you took a 30-minute lunch break.
- Start time: 09:00 → 540 minutes
- End time: 17:30 → 1050 minutes
- Total minutes worked = 1050 − 540 − 30 = 480
- ✅ Result: 8 hour(s) and 0 minute(s)
