In Excel, you can calculate this using the TIME function:
Where A2 contains the start time and B2 contains the end time in Excel's time format.

In Excel, you can calculate this as:
Where C2 contains the duration of the lunch break in hours.
Note: Ensure all times are in Excel's time format (HH:MM:SS) for accurate calculations.
Step-by-Step Guide
- Enter your start time in cell A2 (e.g., 9:00 AM)
- Enter your end time in cell B2 (e.g., 5:00 PM)
- Enter your lunch break duration in cell C2 (e.g., 1 hour)
- In cell D2, enter the formula:
=B2-A2-C2 - Format cell D2 as "Time" to display the result in hours and minutes
This will give you the net hours worked after accounting for the lunch break.
