    Hi yaya1974 ,

    The Table data is shown below:

     

    Try this.

    Avarage = 
VAR _a = [Date]
VAR _table1 = 
ADDCOLUMNS('Table',
"MonthNumber",SWITCH(TRUE(),
LEFT([Date],3) = "Jan",1,
LEFT([Date],3) = "Feb",2,
LEFT([Date],3) = "Mar",3,
LEFT([Date],3) = "Apr",4,
LEFT([Date],3) = "May",5,
LEFT([Date],3) = "Jun",6,
LEFT([Date],3) = "Jul",7,
LEFT([Date],3) = "Aug",8,
LEFT([Date],3) = "Sep",9,
LEFT([Date],3) = "Oct",10,
LEFT([Date],3) = "Nov",11,
LEFT([Date],3) = "Dec",12
)
)
VAR _table2 = ADDCOLUMNS(_table1,
"Rank",RIGHT([Date],2) * 100 + [MonthNumber])
VAR _table3 = ADDCOLUMNS(_table2,
"Begin",IF( [MonthNumber] >=1 && [MonthNumber] <=6,
(RIGHT([Date],2) - 1) * 100 + 5,
(RIGHT([Date],2) - 1) * 100 + 11),
"End",IF( [MonthNumber] >=1 && [MonthNumber] <=6,
(RIGHT([Date],2) - 1) * 100 + 10,
RIGHT([Date],2) * 100 + 4)
)
VAR _table4 = ADDCOLUMNS(_table3,"Average",AVERAGEX(FILTER(_table3,[Rank] >= EARLIER([Begin]) && [Rank] <= EARLIER([End])),[Input]))
RETURN MAXX(FILTER(_table4,[Date] = _a),[Average])

    Final output

    Hi yaya1974 ,

    I apologize for not seeing your message until now, are you trying to calculate a three month average the way I marked it?

    Try this

     

    Column = 
VAR _a = [Date]
VAR _table1 = 
ADDCOLUMNS('Table',
"MonthNumber",SWITCH(TRUE(),
LEFT([Date],3) = "Jan",1,
LEFT([Date],3) = "Feb",2,
LEFT([Date],3) = "Mar",3,
LEFT([Date],3) = "Apr",4,
LEFT([Date],3) = "May",5,
LEFT([Date],3) = "Jun",6,
LEFT([Date],3) = "Jul",7,
LEFT([Date],3) = "Aug",8,
LEFT([Date],3) = "Sep",9,
LEFT([Date],3) = "Oct",10,
LEFT([Date],3) = "Nov",11,
LEFT([Date],3) = "Dec",12
)
)
VAR _table2 = ADDCOLUMNS(_table1,
"Rank",RIGHT([Date],2) * 100 + [MonthNumber])
VAR _table3 = ADDCOLUMNS(_table2,
"Begin",
SWITCH(TRUE(),
[MonthNumber] >= 1 && [MonthNumber] <= 3,(RIGHT([Date],2) - 1) * 100 + 5 ,
[MonthNumber] >= 4 && [MonthNumber] <= 6,(RIGHT([Date],2) - 1) * 100 + 8 ,
[MonthNumber] >= 7 && [MonthNumber] <= 9,(RIGHT([Date],2) - 1) * 100 + 11 ,
RIGHT([Date],2) * 100 + 2
)
,
"End",
SWITCH(TRUE(),
[MonthNumber] >= 1 && [MonthNumber] <= 3,(RIGHT([Date],2) - 1) * 100 + 7 ,
[MonthNumber] >= 4 && [MonthNumber] <= 6,(RIGHT([Date],2) - 1) * 100 + 10 ,
[MonthNumber] >= 7 && [MonthNumber] <= 9,RIGHT([Date],2) * 100 + 1 ,
RIGHT([Date],2) * 100 + 4
)
)
VAR _table4 = ADDCOLUMNS(_table3,"Average",AVERAGEX(FILTER(_table3,[Rank] >= EARLIER([Begin]) && [Rank] <= EARLIER([End])),[Value]))
RETURN MAXX(FILTER(_table4,[Date] = _a),[Average])

     

    If I have misunderstood, please provide simple data and show the expected results as a picture.

      Yes that is what I am looking for.  So I just change the numbers to match the months I need calculated, correct?  Like begins at 3 ends at 5, begins at 6 ends at 8, begins at 9 ends at 11, begins at 12, ends at 2.

      I reallly appreciate your help!!  Thanks so much

      Sorry to keep bothering.  the formula works, just cannot get the results for all 4 quarters to match.  Can you help still?  Here is the pic you asked for.

       

       

      Appreciate your help!

        Oh and this is what I changed to get results,  it works but missing a quarter..............hmmmm

         

        Its missing Q2 and Q1 is incorrect.  I know its probably a simple change and I will keep trying to get it right.  Any help is great!  Thank you!
