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

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