Dax solution required (how to calculate frequency)

Hi saad_mce 
Please refer to the sample file with the solution https://we.tl/t-txANOKHgtj

Actually this solution still need some work to consider working days only but I still don't fully understand your business logic. Like for example if dates are no consecutive but the gap is actually a weekend or holiday shall we count it or not. Please provide a brief description along with holidays table. I will be Little bet more complex but we can produce accurate results.

Count Result = 
SUMX ( 
    SUMMARIZE ( 'Raw Data', 'Raw Data'[Date] ),
    VAR CurrentDate = 'Raw Data'[Date]
    VAR PreviousDates = FILTER ( 'Raw Data', 'Raw Data'[Date] < CurrentDate )
    VAR PreviousDate = MAXX ( PreviousDates, 'Raw Data'[Date] )
    RETURN
        IF (
            CurrentDate - PreviousDate > 1,
            1
        )
)

Hi saad_mce 
Here is the updated solution considering both weekends and holidays https://we.tl/t-2MGgJsKTAQ

I have included a sample holiday table. You just need to update as per your local holidays

Count Result 2 = 
VAR MaxDate = MAX ( 'Raw Data'[Date] )
VAR MinDate = MIN ( 'Raw Data'[Date] )
VAR T1 = CALENDAR ( MinDate, MaxDate )
VAR T2 = VALUES ( Holidays[Holidays] )
VAR T3 = FILTER ( T1, [Date] IN T2 || WEEKDAY ( [Date], 2 ) IN { 6, 7 }  )
VAR T4 = SUMMARIZE ( 'Raw Data', 'Raw Data'[Date] )
VAR T5 = DISTINCT ( UNION ( T3, T4 ) )
RETURN
    SUMX ( 
        T5, 
        VAR CurrentDate = [Date]
        VAR PreviousDates = FILTER ( T5, [Date] < CurrentDate )
        VAR PreviousDate = MAXX ( PreviousDates, [Date] )
        RETURN
            IF (
                CurrentDate - PreviousDate > 1,
                1
            )
    )
