# Help with dax calculation - outstanding complaints

Hi,

Please I need to calculate the lenght of days of an outstanding complaints.

Below I have number of outstanding complaints and a start date. The end date is 1/12/2019

So I want a dax code which can calculate how many days has the complaints been open.For example on the 10/07/2019 we have 2 outstanding complaints open, to get the lenght of days will be:1/12/2019 - 10/07/2019 will be 144 days open. How do I calculate it as a measure without typying the dates manually.

Thanks,
Chukliz

Hi, Chukliz! Have you consider to use DATEDIFF function?
https://docs.microsoft.com/en-us/dax/datediff-function-dax

Sorry I forgot to mention that the dates in my table is upto 12/31/2019 but I only want the End date for this calculation to be 01/12/2019

Have you tried to put DATE(2019,12,01) as the End Day?
= DATEDIFF (DATE (2019,4,1), DATE (2019,12,1), DAY)

Hi youâ€™ve got serveral options here, first like @Ivanka suggested:

``````Length DATEDIFF =
VAR StartDate = SELECTEDVALUE( tOutstandingComplaints[StartDate] )
VAR EndDate = DATE(2019, 12, 1)
RETURN

DATEDIFF( StartDate, EndDate, DAY )
``````

.
But you could also use COUNTROWS in your Dates table:

``````Length COUNTROWS =
VAR StartDate = SELECTEDVALUE( tOutstandingComplaints[StartDate] )
VAR EndDate = DATE(2019, 12, 1)
RETURN

CALCULATE(
COUNTROWS( Dates ),
FILTER( ALL(Dates),
Dates[Date] > StartDate &&
Dates[Date] <= EndDate
)
)
``````

.
The bonus here is that you could also exclude weekends:

``````Length COUNTROWS No Weekends =
VAR StartDate = SELECTEDVALUE( tOutstandingComplaints[StartDate] )
VAR EndDate = DATE(2019, 12, 1)
RETURN

CALCULATE(
COUNTROWS( Dates ),
FILTER( ALL(Dates),
Dates[Date] > StartDate &&
Dates[Date] <= EndDate &&
Dates[IsWorkingDay] = TRUE()
)
)
``````
