**Introduction:** The 8 Hour Shift Calculator With Lunch is a versatile tool designed to determine the total time duration in milliseconds, taking into account lunch breaks, based on the number of shifts and hours per shift. Whether you are managing workforce schedules or planning projects, this calculator provides an accurate reflection of the effective working hours.

**Formula:** To calculate the time duration, the formula is applied by multiplying the number of shifts by the effective hours per shift (subtracting the lunch break duration), then by 60 (minutes per hour), then by 60 (seconds per minute), and finally by 1000 (milliseconds per second).

**How to Use:**

- Enter the number of shifts in the “Number of Shifts” input field.
- Enter the hours per shift in the “Hours per Shift” input field.
- Enter the duration of the lunch break in the “Lunch Break Duration” input field.
- Click the “Calculate” button.
- The result will be displayed below the button, indicating the total time duration in milliseconds for the specified number of shifts with lunch breaks.

**Example:** Suppose a business operates for 20 shifts, with each shift lasting for 8 hours and a lunch break of 30 minutes. Enter “20” in the “Number of Shifts” field, enter “8” in the “Hours per Shift” field, enter “30” in the “Lunch Break Duration” field, click “Calculate,” and the result will show the total time duration in milliseconds.
