Anonymous Do you have a date table with contiguous dates? Personally, I don't recommend using TI functions and just using non-sugar syntax functions instead. For example, if you want the first date a year ago, you can simply use. DATE([Financial Year]-1,1,1) for example.

Also, see if my Time Intelligence the Hard Way provides a different way of accomplishing what you are going for.

Dear Greg_Deckler ,

 

First of all, thank you so much for the help!

I tried your solution I created a column with DATE([Financial Year]-1,1,1) function and its returns 01/01/2020. but I am using the financial year which should be 01/04/2020. and also i can not select DATE([Financial Year]) column in measure so I creat a column. so how can we gain financial year do you have any idea?

    Anonymous Ah, well if you are using a financial year then I would definitely avoid TI functions as they are designed specifically to work with a standard Gregorian calendar, which essentially makes them next to useless. So, the answer to your question lies in how good of a financial calendar you have. Can you provide a sample of your financial calendar? Do you have a column in your financial calendar that is the day of the year for the financial calendar? For example, 1/4/2020 would have a value of 1, 1/5/2020 would be 2 and so on. If you have that then the answer is essentially a LOOKUPVALUE or MAXX(FILTER()) situation such as:

    MAXX(FILTER('Dates',[Year] = [Financial Year] - 1 && [Day of Year] = 1),[Date])

      Dear Greg_Deckler ,

       

      Basically i am calulating percentage diffrence with respect to last year.

       

      for that i have created this measure : 

       

      %ChangeSessions =
      var cp = SUM('Website Performance'[Sessions])
      var pp = CALCULATE(SUM('Website Performance'[Sessions]), DATESBETWEEN(Dates[Date], [StarOfLastYear], [EndOfLastYear]))
      Return
      DIVIDE((cp - pp), pp, 0)
       
      StarOfLastYear = FIRSTDATE(SAMEPERIODLASTYEAR(Dates[Date]))
      EndOfLastYear = [StarOfLastYear] + [DaysInThisPeriod] - 1
      DaysInThisPeriod = DATEDIFF([StartOfThisPeriod], [EndOfThisPeriod], DAY) + 1
      StartOfThisPeriod = FIRSTDATE(Dates[Date])
      EndOfThisPeriod = LASTDATE(Dates[Date])
       
       
       to find out last year change to this date in my case 01/04/2021-30/08/2021 to 01/04/2020-30/08/2020
       
      my date table is like this : 
       
       
      It works perfectly fine without a country filter but when I add country filter its shows this error

        Anonymous Can you change the relationship cross-filter direction to Single from Both? Also, I would add this column to your financial calendar:

        FiscalDayOfYear = 
  VAR __Date = [Date]
  VAR __FinancialYear = [Financial Year]
RETURN
  COUNTROWS(FILTER('Dates',[Financial Year]=__FinancialYear && [Date]<=__Date))
