DateDiff with time excluding weekends

[Anonymous]

Hi All,

I have a date table and fact table which are connected to each other via one-to-many.

I'm using the following dax to get the out put:

#Days_Den =

VAR _d = DATEDIFF([ExpectedStartDate], [ExpectedEndDate], SECOND)

VAR _min = DIVIDE(_d,60)

VAR _hour = DIVIDE(_min,60)

VAR _day = DIVIDE(_hour,24)

VAR _weekend = CALCULATE([SumWeekEnds],ALL(Dates),FILTER(Dates,Dates[Date]>=SELECTEDVALUE('Table'[StartDate]) && Dates[Date]<=SELECTEDVALUE('Table'[EndDate])))

return

_day - _weekend

the "_weekend" variable is giving output as 1 day which is ruining the whole output and is unable to get the exact difference as needed.

I'm looking for help calculating the difference between two dates along with time which helps me eliminate weekends with the specified timestamp on the record.

Any help on this would be appreciated!

Regards,
Mahesh

Hi @Anonymous ,

Due to I don't know your data model, I will share a workaround by my sample.

Tables:

Date = ADDCOLUMNS(CALENDARAUTO(),"Year",YEAR([Date]),"Month",MONTH([Date]),"WeekDay",WEEKDAY([Date],2))

Measure:

#Days_Den = 

VAR _d = DATEDIFF(MAX('Table'[ExpectedStartDate]), MAX('Table'[ExpectedEndDate]), SECOND)
VAR _min = DIVIDE(_d,60)
VAR _hour = DIVIDE(_min,60)
VAR _day = DIVIDE(_hour,24)
VAR _weekend = CALCULATE(COUNT('Date'[Date]),FILTER('Date','Date'[WeekDay] in {6,7} && 'Date'[Date]>=MAX('Table'[ExpectedStartDate]) && 'Date'[Date]<= MAX('Table'[ExpectedEndDate])))

return 
_day - _weekend

Result is as below.
