1. What is Time Duration Calculation?

Time duration calculation determines the net time between two points, accounting for breaks or interruptions. It's essential for accurate time tracking in work, projects, and various scheduling applications.

2. How Does the Calculator Work?

The calculator uses the duration formula:

Where:

• \( D \) — Net duration (hours)
• \( E \) — End time
• \( S \) — Start time
• \( \sum B \) — Sum of all break times

Explanation: The calculator first calculates the total time between start and end, then subtracts all break times to determine the net working or active duration.

3. Importance of Accurate Time Tracking

Details: Accurate time duration calculation is crucial for payroll processing, project management, billing clients, productivity analysis, and compliance with labor regulations.

4. Using the Calculator

Tips: Enter start and end times in 24-hour format. Input break durations in hours (e.g., 0.5 for 30 minutes). You can leave break fields blank if no breaks were taken.

5. Frequently Asked Questions (FAQ)

Q1: What if my work spans midnight?
A: The calculator automatically handles cases where the end time is earlier than the start time (indicating crossing midnight).

Q2: How precise are the calculations?
A: Calculations are precise to two decimal places (approximately 1 minute precision).

Q3: Can I add more than three breaks?
A: Currently the calculator supports three break inputs. For more breaks, you can sum them and enter the total in one break field.

Q4: What time format should I use?
A: Use the 24-hour format (HH:MM) for time inputs. For example, 2:30 PM should be entered as 14:30.

Q5: Can this calculator handle negative durations?
A: No, the calculator will return an error if break times exceed the total time between start and end.
