**Introduction:** Welcome to the Time Clock Calculator App, a user-friendly tool designed to calculate the total hours between a start time and an end time. Whether you’re tracking work hours, managing projects, or simply curious about time intervals, this app provides a quick and easy solution. Let’s explore how to use it effectively.

**Formula:** The total hours are calculated by subtracting the start time from the end time and converting the result to hours. The formula is: Total Hours = (End Time – Start Time) / (60 minutes per hour * 60 seconds per minute).

**How to Use:**

- Enter the start time using the 24-hour format.
- Input the end time using the 24-hour format.
- Click the “Calculate” button to find the total hours between the two specified times.

**Example:** Suppose you start work at 9:00 AM and finish at 5:30 PM. Enter these times, click “Calculate,” and the result will show the total hours worked.
