Biz Days in a month calculation

[v4anand18]

Hello friends,

I am new to Power BI. I need help in calculating the "Number of Business Days in a Month" and "Business Days Passed in a Month" as a measure. I tried the below formula for "Biz Days in a Mth" but i get a wrong value. For eg. the no of business days in May is 22 and with the below mentioned formula i get 20.75 days. I already have a calculated column "Business Days per Month" My data looks like this

I need these measures to calculate an estimate. Please help

@v4anand18,

What field would you like to drag to the visual with the measure? You can use DAX below to calculate "Number of Business Days in a Month" measure, when you drag Month and this measure to a table visual, the measure should return your expected result.

Number of Business Days in a Month = SUM('Business Days 2018'[IS BusinessDay])

Lydia

Thanks Lydia. I used the DAX formula you posted.

It works.
