Counting number of weekdays between column with start date and column with end date

Dear all,
I would like to requst your assistance on how to add a new column that counts the number of mondays (or any other day) between a date column with a starting date and a date column with an end date? 

Both DATE_START and DATE_END should be included in the calculation, but if DATE_START and DATE_END are the same date value it should should only copunt as one "monday".

@JK87 You can do something like this:

Measure = 
  VAR __Table = 
    ADDCOLUMNS(
      CALENDAR( [DATE_START], [DATE_END] ),
      "__WeekDay", WEEKDAY( [Date], 2 )
    )
  VAR __Result = COUNTROWS( FILTER( __Table, [__WeekDay] = 1) ) // this is for Monday
RETURN
  __Result
