1. What is a Time Difference Calculator?

Definition: This calculator computes the duration between two times expressed in hours.

Purpose: It helps determine elapsed time for work shifts, project durations, travel times, and other time-based calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Time difference (hours)
• \( E \) — End time (hours)
• \( S \) — Start time (hours)

Explanation: The start time is subtracted from the end time. For overnight periods (when end time is earlier than start time), 24 hours are added to the result.

3. Importance of Time Calculation

Details: Accurate time calculations are essential for payroll, project management, scheduling, and productivity analysis.

4. Using the Calculator

Tips: Enter start and end times in hours (0-24). Decimal values can be used for minutes (e.g., 8.5 = 8:30). The calculator handles overnight periods automatically.

5. Frequently Asked Questions (FAQ)

Q1: How do I input times with minutes?
A: Convert minutes to decimal (30 min = 0.5, 15 min = 0.25). Example: 8:45 AM = 8.75

Q2: Does this work for overnight periods?
A: Yes, the calculator automatically adds 24 hours when the end time is earlier than the start time.

Q3: What's the maximum time difference it can calculate?
A: The maximum difference is 24 hours. For longer periods, you'd need to add days separately.

Q4: Can I use 24-hour format?
A: Yes, the calculator uses 24-hour format (e.g., 13 = 1 PM, 23.5 = 11:30 PM).

Q5: How precise is the calculation?
A: Results are shown with 2 decimal places (about 1 minute precision).
