The calculator will show you:

Formula Explained
The calculation is based on simple time arithmetic:
Adjusted Work Hours = Total Work Hours - (30 minutes / 60 minutes)
Workday End Time = Start Time + Adjusted Work Hours
The calculator converts all times to a 24-hour format for clarity.
Worked Example
Let's say you work 8 hours a day and take a 30-minute lunch break starting at 12:00 PM:
- Total work hours: 8 hours
- Lunch break: 30 minutes at 12:00 PM
- Adjusted work hours: 8 - 0.5 = 7.5 hours
- Workday ends: 12:00 PM + 7.5 hours = 7:30 PM
This means you'll finish work at 7:30 PM instead of 8:00 PM if you didn't take the break.
