1. What is the Hours Calculator?

The Hours Calculator calculates the duration in hours between two timestamps given in seconds. It's useful for time tracking, payroll calculations, and various scheduling applications.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( End \) — End time in seconds
• \( Start \) — Start time in seconds
• 3600 — Number of seconds in one hour (60 seconds × 60 minutes)

Explanation: The formula subtracts the start time from end time to get duration in seconds, then converts to hours by dividing by 3600.

3. Importance of Time Calculation

Details: Accurate time calculation is essential for work hour tracking, billing clients, calculating overtime pay, and analyzing time-based data in various fields.

4. Using the Calculator

Tips: Enter both start and end times in seconds. The end time must be greater than start time, and both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this with minutes instead of seconds?
A: Yes, but you'll need to multiply your minute values by 60 first to convert to seconds.

Q2: What if my end time is before start time?
A: The calculator requires end time to be after start time as it calculates duration, not time differences across days.

Q3: How precise is the calculation?
A: The calculator shows results with 4 decimal places (about 0.36 seconds precision).

Q4: Can I calculate hours across midnight?
A: For time spans crossing midnight, you'll need to use 24-hour format timestamps or add 86400 (seconds in a day) to the end time.

Q5: Is there a maximum time span this can calculate?
A: Technically no, but extremely large values may cause precision issues with floating-point arithmetic.
