1. What is Duration Calculation?

Duration calculation measures the time elapsed between two points in time. This calculator specifically works with 24-hour clock format to determine the exact duration between a start and end time.

2. How Does the Calculator Work?

The calculator uses the following simple formula:

Where:

• Start Time — Beginning point in 24-hour format (HH:MM)
• End Time — Ending point in 24-hour format (HH:MM)

Explanation: The calculator automatically handles overnight durations (when end time is earlier than start time) by adding 24 hours to the result.

3. Importance of Duration Calculation

Details: Accurate duration calculation is essential for time tracking, work hour calculations, billing, project management, and various scheduling applications.

4. Using the Calculator

Tips: Enter both times in 24-hour format (e.g., 13:30 for 1:30 PM). The calculator will automatically compute the duration in hours, including fractional hours for minutes.

5. Frequently Asked Questions (FAQ)

Q1: What if my end time is earlier than start time?
A: The calculator automatically assumes this is an overnight duration and adds 24 hours to the result.

Q2: How precise is the calculation?
A: Results are precise to two decimal places, accounting for both hours and minutes.

Q3: Can I use 12-hour format?
A: No, this calculator specifically uses 24-hour format for unambiguous time representation.

Q4: What's the maximum duration this can calculate?
A: The calculator can handle durations up to 24 hours. For longer periods, consider using a date-time calculator.

Q5: Why does the result show decimal hours?
A: Decimal hours (e.g., 1.5 hours for 1 hour 30 minutes) are often more useful for calculations than hours:minutes format.
