Example Calculation
Let’s understand how the calculator works with a real example:

- End Time: 17:00
- Extra Hours: 2
- Extra Minutes: 30
Step 1: Calculate Time Difference
From 09:30 to 17:00 = 7 hours 30 minutes
Step 2: Add Extra Time
Extra time = 2 hours 30 minutes
Step 3: Total Duration
7:30 + 2:30 = 10:00 (10 hours total)
Step 4: Final Time
Start time (09:30) + 10 hours = 19:30
So the calculator will display:
- Total Duration: 10:00
