1. What is Time Subtraction?

Time subtraction calculates the difference between two points in time. This is useful for tracking durations, calculating elapsed time, or determining time intervals between events.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Time1 — The later time point
• Time2 — The earlier time point

Explanation: The calculation converts both times to DateTime objects and computes the difference in hours, including fractional hours.

3. Importance of Time Calculation

Details: Accurate time difference calculation is crucial for work hour tracking, scientific experiments, billing systems, and any application requiring precise duration measurement.

4. Using the Calculator

Tips: Enter both times in 24-hour format (HH:MM). The calculator will automatically compute the difference in hours, including decimal fractions for minutes.

5. Frequently Asked Questions (FAQ)

Q1: Does this work across midnight?
A: Yes, the calculator correctly handles cases where Time1 is on the following day from Time2.

Q2: What's the maximum time difference that can be calculated?
A: There's no practical limit - differences of any duration can be calculated.

Q3: How precise is the calculation?
A: The calculation is precise to the second, though results are displayed in hours with two decimal places.

Q4: Can I calculate differences in days instead of hours?
A: The current version only displays hours, but you can divide by 24 to get days.

Q5: Does daylight saving time affect the calculation?
A: No, the calculator works with pure time values without date or timezone context.
