1. What is a Time Difference Calculator?

Definition: This calculator computes the difference between two time values measured in hours.

Purpose: It helps determine the duration between two events, calculate elapsed time, or find the interval between two timestamps.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \Delta T \) — Time difference (hours)
• \( T_2 \) — Later time (hours)
• \( T_1 \) — Earlier time (hours)

Explanation: The calculator subtracts the earlier time from the later time to determine the duration between them.

3. Importance of Time Difference Calculation

Details: Accurate time calculations are essential for project scheduling, work hour tracking, scientific experiments, and many other applications.

4. Using the Calculator

Tips: Enter both time values in hours. The result will show the difference (T2 - T1). Negative results indicate T1 was later than T2.

5. Frequently Asked Questions (FAQ)

Q1: Can I use decimal hours?
A: Yes, you can enter decimal values (e.g., 1.5 hours = 1 hour and 30 minutes).

Q2: What if I get a negative result?
A: A negative result means Time 1 was later than Time 2. The absolute value shows the duration.

Q3: How can I convert minutes to hours?
A: Divide minutes by 60 (e.g., 90 minutes = 1.5 hours).

Q4: Can this calculate days or weeks?
A: Convert larger units to hours first (1 day = 24 hours, 1 week = 168 hours).

Q5: How precise is the calculation?
A: Results are calculated to two decimal places for minutes precision.
