Cal sale between dates

Anonymous , replace the var with following

VAR EL = DATE(year(FAST[International OCD]),month(FAST[International OCD])+2,day(FAST[International OCD]))
VAR SL = DATE(year(FAST[International OCD]),month(FAST[International OCD])-6,day(FAST[International OCD]))

or try rolling with a date tbale

Rolling 6 till next 2 month = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],ENDOFMONTH(dateadd(Sales[Sales Date],2,month)),-6,MONTH))

or use 8

Rolling 8 till next 2 month = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],ENDOFMONTH(dateadd(Sales[Sales Date],2,month)),-8,MONTH))

Hi amitchandak, 

Thank for 😀. 
what is the difference between my DATEADD function and the DATE function you are using.
