1. What is a Time Duration Calculator?

Definition: This calculator computes the duration between two points in time, showing results in both hh:mm:ss format and decimal hours.

Purpose: It helps professionals and individuals accurately measure time intervals for work tracking, project management, and scheduling.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Duration \) — Time difference between end and start
• \( EndTime \) — The ending time point
• \( StartTime \) — The starting time point

Explanation: The calculator handles overnight durations automatically and provides results in both time format and decimal hours for different use cases.

3. Importance of Time Duration Calculation

Details: Accurate time measurement is crucial for payroll, billing, productivity analysis, and meeting scheduling across various industries.

4. Using the Calculator

Tips: Enter both start and end times in 24-hour format. The calculator automatically handles overnight durations (when end time is earlier than start time).

5. Frequently Asked Questions (FAQ)

Q1: How are overnight durations handled?
A: The calculator automatically assumes end times earlier than start times occur on the following day.

Q2: Why provide both time format and decimal hours?
A: Time format is human-readable while decimal hours are better for calculations and payroll systems.

Q3: What's the maximum duration this can calculate?
A: It can calculate up to 24 hours. For longer durations, consider a date-time calculator.

Q4: How precise is the calculation?
A: It calculates to the second, though results are typically displayed to the minute or hundredth of an hour.

Q5: Can I use AM/PM format?
A: The input uses 24-hour format for consistency, but you can convert AM/PM times before entering.
