This tool will help you easily calculate the total hours worked by adding up time intervals.

## Usage Instructions

To use the Kronos time calculator:

- Enter the start time in HH:MM format.
- Enter the end time in HH:MM format.
- Enter the total break time in minutes.
- Click “Calculate” to get the total working time, excluding breaks.

## How It Calculates

The calculator works by taking the start and end times, converting them into a Date object, and then calculating the difference in minutes. It then subtracts the break time you provided and converts the total minutes back into hours and minutes to give you the final result.

## Limitations

Currently, this calculator does not handle cases where the end time is past midnight. Also, it assumes a break time of 0 minutes if you leave the break time field empty. Make sure to enter the times in 24-hour format.
