1. What is Time Difference Calculation?

The time difference calculation computes the duration between two points in time. It's useful for tracking work hours, project durations, or any time-based intervals.

2. How Does the Calculator Work?

The calculator uses simple time arithmetic:

Where:

• \( End\ Time \) — The later time point (HH:MM format)
• \( Start\ Time \) — The earlier time point (HH:MM format)

Explanation: The calculation accounts for both hours and minutes, converting the result to decimal hours.

3. Importance of Time Calculation

Details: Accurate time calculation is essential for payroll, billing, productivity tracking, and project management.

4. Using the Calculator

Tips: Enter both start and end times in HH:MM format (24-hour clock). The calculator will compute the duration in hours (including fractional hours).

5. Frequently Asked Questions (FAQ)

Q1: Does this work across midnight?
A: Yes, the calculator correctly handles cases where the end time is the next day.

Q2: How precise is the calculation?
A: Results are precise to two decimal places (e.g., 3.50 hours = 3 hours 30 minutes).

Q3: Can I use AM/PM format?
A: The calculator uses 24-hour format, but you can convert AM/PM times before entering (e.g., 2:30 PM = 14:30).

Q4: What if I get a negative result?
A: The calculator automatically handles time differences correctly, even if the end time is earlier than start time (interpreted as next day).

Q5: Can this calculate days as well as hours?
A: This version calculates hours only. For day calculations, you'd need to account for date differences.
