How Time Calculator Works

The calculator features:

• Input fields for hours and minutes
• Addition and subtraction operations
• Input validation
• Error handling
• Responsive design
• Clean, modern styling

Users can:

1. Enter the first time (hours and minutes)
2. Select operation (+ or -)
3. Enter the second time
4. Click “Calculate” to see the result

The result is displayed in HH:MM format, and it handles:

• Negative results
• Input validation
• Leading zeros
• Error messages for invalid inputs

Would you like me to modify anything about the calculator? I can:

• Add more operations
• Change the styling
• Add more validation rules
• Include AM/PM support
