Count open days of any month

[Anonymous]

Hello, 

I'm working on a dax to calculate the open days in a month. For example, I would like to calculate the open days of March month. So the dax that I wrote is : 

OD = CALCULATE(DISTINCTCOUNT('Calendar'[Date]),FILTER('Calendar','Calendar'[Month]=MONTH(NOW())+1))

So the result is: 31 days, is the number of all days of March month.

Do you have any tips to calculate the open days of any month? 

Thank you in advance.

Regards,

Not very clear what is open days?

Total day in current month = day(eomonth(Today(),0)

Total day in next month = day(eomonth(Today(),1)

Open days are the days that we work on: from Monday to Friday. For example, for March the open days are 23, not 31. I would like to calculate it for all months!

@Anonymous , for next month

Work Day = COUNTROWS(FILTER(ADDCOLUMNS(CALENDAR(EOMONTH(TODAY(),0)+1, EOMONTH(TODAY(),1)),"WorkDay", if(WEEKDAY([Date],2) <6,1,0)),[WorkDay] =1))
