How 8-Hour Shift Calculator Works
The calculation uses the formula:
Where:
- Start Time = Beginning of shift (e.g., 9:00 AM)
- Work Hours = Actual working time (typically 8 hours)
- Unpaid Breaks = Lunch break time (e.g., 30 minutes)
- Paid Breaks = Short breaks included in work time
- Total Duration = Work Hours + All Breaks
Key Concepts Explained
Paid vs Unpaid Breaks
Paid breaks (typically 15 minutes) are included in work time and compensated. Unpaid breaks (typically 30-60 minute lunch) extend shift duration but aren't paid.
Shift Duration
Total shift duration includes all work time plus breaks. An 8-hour work shift with a 30-minute lunch typically runs 8.5 hours from start to finish.
