1. What is Time Duration?

Time duration is the amount of time that passes between two specific points in time (start and end). It's commonly used in project management, work tracking, and various time-based calculations.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Start Time — The beginning point of the time period
• End Time — The ending point of the time period

Explanation: The calculator converts both timestamps to Unix time (seconds since epoch), calculates the difference, and converts the result to hours.

3. Importance of Time Duration Calculation

Details: Accurate time duration calculation is essential for billing, payroll, project scheduling, productivity measurement, and various scientific experiments.

4. Using the Calculator

Tips: Enter both start and end times in the datetime-local format (YYYY-MM-DDTHH:MM). The end time must be after the start time.

5. Frequently Asked Questions (FAQ)

Q1: What time format should I use?
A: The calculator uses the standard HTML datetime-local format (YYYY-MM-DDTHH:MM).

Q2: Can I calculate duration across multiple days?
A: Yes, the calculator handles durations of any length, from seconds to years.

Q3: Why is the result in hours?
A: Hours are a commonly used unit for duration. You can easily convert to other units if needed.

Q4: Does this account for daylight saving time?
A: The calculation uses the exact time difference, but DST transitions may need manual adjustment.

Q5: Can I calculate future durations?
A: Yes, as long as your end time is after your start time, future durations can be calculated.
