How to Calculate Business Days in Power BI
In Power BI, you can calculate business days by using DAX formulas and custom tables. Here’s a step-by-step guide on how to do it:
- Create a custom table that defines your business days. This table should list all the valid business days and exclude weekends and holidays.
- Create a relationship between the custom table and your date column in the main table.
- Create a new calculated column or measure to calculate the number of business days. Use the following DAX formula:
- Now you can use the "Business Days" calculated column or measure in your Power BI visualizations.
Example custom table:
| Date |
|---|
| 01/01/2021 |
| 01/04/2021 |
| 01/05/2021 |
| 01/06/2021 |
| 01/07/2021 |
| 01/08/2021 |
| … |
Business Days =
CALCULATE(
COUNTROWS('CustomTable'),
FILTER(
'CustomTable',
'CustomTable'[Date] >= MIN('MainTable'[Date]) &&
'CustomTable'[Date] <= MAX('MainTable'[Date])
)
)
This formula calculates the count of business days in the custom table between the minimum and maximum dates in the main table.
By following these steps, you can easily calculate business days in Power BI. This allows you to analyze data based on the number of working days, which can be helpful for various business scenarios.
