DAX - Counting a specific day between dates

I have two date columns in a table, "Start Date" and "End Date". I would like to count how many Mondays there are in this range.

 

@tamerj1  , do you have any idea how to solve it?

Hi @Diego_Vialle ,

 

Try this.

count of monday =
VAR _weekdayofstartdate =
    WEEKDAY ( 'Table'[Start Date], 2 )
VAR _weekdayofenddate =
    WEEKDAY ( 'Table'[End Date], 2 )
VAR _weeks_1 =
    IF ( _weekdayofstartdate > _weekdayofenddate || _weekdayofstartdate = 1, 1, 0 )
VAR _days =
    DATEDIFF ( 'Table'[Start Date], 'Table'[End Date], DAY )
VAR _weeks_2 =
    INT ( DIVIDE ( _days, 7 ) )
VAR _result = _weeks_1 + _weeks_2
RETURN
    _result

Here is the solution >> Counting working days in DAX - SQLBI

 

You need to make slight changes here

 

'Date'[IsWorkingDay] = WEEKDAY( 'Date'[Date] ) IN { 2}

 

Mondays_Count =
CALCULATE(
COUNTROWS ( 'Calendar Table'),
DATESBETWEEN ( 'Calendar Table'[Date], orders_[Order Date], orders_[Ship Date]-1 ),
'Calendar Table'[IsMonday] = TRUE,
ALL ( orders_ )
)
