**Calculation History**

A work hours calculator is a tool that allows users to calculate the number of hours worked in a given period of time. This can be useful for tracking employee hours, calculating pay, and managing time.

**Concepts**

The following are some of the key concepts that underlie work hours calculators:

**Work hours:**Work hours are the number of hours that an employee works in a given period of time. This can be measured on a daily, weekly, or monthly basis.**Overtime:**Overtime is the number of hours that an employee works in excess of their standard work hours. Overtime is paid at a higher rate than regular hours.**Paid time off (PTO):**PTO is the amount of time that an employee is paid for to take off from work. PTO can be used for vacation, sick days, and other personal days.

**Formulae**

The following formula is used to calculate work hours:

```
Work hours = Start time - End time - Breaks
```

where:

- Start time is the time that the employee began working
- End time is the time that the employee finished working
- Breaks is the total amount of time that the employee took for breaks

For example, if an employee starts working at 8:00 AM and finishes working at 5:00 PM with a 30-minute lunch break, their work hours would be calculated as follows:

```
Work hours = 5:00 PM - 8:00 AM - 30 minutes = 8.5 hours
```

To do this, you would enter the following information into the calculator:

- Start time for each employee
- End time for each employee
- Break time for each employee

The calculator would then display the total number of work hours for each employee. You can then use this information to calculate employee pay and manage employee time.
