Calculating Number of Workdays for Each Month, use result to divide the result of another measure

[jamecl]

I have the following calendar table where I have the working days per month. I want to get the total work days per month and use that value in another measure.

To give you some background, I'm dividing the number of estimated work days to complete a project by the number of work days in a month to get the number of resources needed for the next year. I know it can't be that difficult, but I'm fairly new to Power BI.

In dax you may create a newcolum and use this

WorkDayMOnth = 
var month = month(dimCalendar[Date])
var year = year(dimCalendar[Date])
return
CALCULATE(COUNT(dimCalendar[Date]),filter(all(dimCalendar[Date]),YEAR(dimCalendar[Date])=year && MONTH(dimCalendar[Date])=month && WEEKDAY(dimCalendar[Date]) in {2,3,4,5,6}))

Thank you.

How do I account for holidays in the column? The 'Work Time' column designates work days - 1 for a work day 0 for holiday or weekend.

Also, I need to take the value in the WorkDayMonth column and divide it into a measure -  I'm not quite sure how to do that.

Here is the measure I'm working with - 

AvailabilityDays = Divide(SUM(Availability[Capacity])-(SUM('Engagements By Day'[Engagement Total Work])+sum('Assignments By Day'[Assignment Total Work])),6.8) / "number of working days"
