This article will guide you through the process of computing working days, allowing you to efficiently analyze timelines for projects, tasks, or any time-sensitive activity.

Understanding the NETWORKDAYS Function

The NETWORKDAYS function in DAX is specifically designed to calculate the number of working days between two dates.

By default, the function considers Monday through Friday as working days, excluding weekends.

However, you can customize the function to account for holidays and adjust which days are recognized as working days.

Basic Syntax

Here’s the basic syntax for calculating working days in Power BI:

Working Days Between = NETWORKDAYS(my_data[Start Date], my_data[End Date])

In this example, a new column named Working Days Between will be created that displays the number of working days between the Start Date and the End Date for each entry in the my_data table.

Step-by-Step Guide: Calculating Working Days

Example Scenario

Let’s say you’re working with a table called my_data, which contains information about various tasks along with their respective Start Date and End Date.

You want to create a new column that shows the number of working days each task takes.

Step 1: Open Power BI and Navigate to Your Table

1. Open Power BI Desktop: Launch your Power BI project and load the relevant dataset.
2. Select Your Table: In the data view, find and click on the my_data table that contains your dates.

Step 2: Create a New Column

1. Access Table Tools: Go to the Table tools tab in the ribbon.
2. Add a New Column: Click on the New column icon to initiate a new column creation.

Step 3: Enter the DAX Formula

In the formula bar, enter the following DAX expression:

Working Days Between = NETWORKDAYS(my_data[Start Date], my_data[End Date])

Step 4: Review the Results

After typing in the formula, Power BI will calculate the number of working days for each task based on the given start and end dates. The newly created column will display results similar to the following:

• 22 working days between January 1, 2024, and January 30, 2024.
• 1 working day between January 5, 2024, and January 5, 2024.
• 5 working days between January 15, 2024, and January 19, 2024.

Customizing the Calculation

If you need to account for specific holidays or customize which days are considered working days (such as excluding Mondays), you can modify the NETWORKDAYS function accordingly.

Refer to the NETWORKDAYS documentation for detailed information on how to define non-working days and holidays.

Conclusion

Calculating working days between two dates in Power BI using the NETWORKDAYS function is a straightforward process that significantly aids in project planning and resource management.

By creating a dedicated column for working days, you can gain valuable insights into task durations and make more informed decisions.
