How To Calculate Difference Between Dates in Same Column excluding weekends

Hi Lior0707 ,

According to your description, Greg_Deckler  gave a good solution on dates in two columns.

You mentioned that your dates are in same column. In this case, there are different solutions based on different data.

1. If the column only have two date rows.

First add an index column in Power Query, then create a measure.

Date diff =
VAR Calendar1 =
    CALENDAR (
        MAXX ( FILTER ( ALL ( 'Table' ), 'Table'[Index] = 1 ), 'Table'[Date] ),
        MAXX ( FILTER ( ALL ( 'Table' ), 'Table'[Index] = 2 ), 'Table'[Date] )
    )
VAR Calendar2 =
    ADDCOLUMNS ( Calendar1, "WeekDay", WEEKDAY ( [Date], 2 ) )
RETURN
    COUNTX ( FILTER ( Calendar2, [WeekDay] < 6 ), [Date] )

Get the result.

2. If there are multiple rows of dates in the column, and you want to compare the difference between every two rows of dates.

First add an index column in Power Query, then create a measure.

Date diff2 =
VAR Calendar1 =
    CALENDAR (
        MAX ( 'Table'[Date] ),
        IF (
            MAX ( 'Table'[Index] ) <> MAXX ( ALL ( 'Table' ), 'Table'[Index] ),
            MAXX (
                FILTER ( ALL ( 'Table' ), 'Table'[Index] = MAX ( 'Table'[Index] ) + 1 ),
                'Table'[Date]
            ),
            MAX ( 'Table'[Date] )
        )
    )
VAR Calendar2 =
    ADDCOLUMNS ( Calendar1, "WeekDay", WEEKDAY ( [Date], 2 ) )
RETURN
    COUNTX ( FILTER ( Calendar2, [WeekDay] < 6 ), [Date] )

Get the result.

I attach my sample below for reference.
