Hi Nyx ,
Here are the steps you can follow:
1. Create calculated table.
Date = CALENDAR( DATE( 2022,1,1), DATE( 2022,12,31))2. Create calculated column.
Column = var _table1= SUMMARIZE( 'Table1', 'Table1'[Date], "Index1" MAXX(FILTER(ALL('Date'), FORMAT( 'Date'[Date],"mmm")=LEFT('Table1'[Date],3)),MONTH('Date'[Date]))) var _table2= ADDCOLUMNS( _table1,"Index2",IF([Index1]<=6, MAXX(FILTER(_table1,[Index1]=EARLIER([Index1])+6),[Index1]), MAXX(FILTER(_table1,[Index1]=EARLIER([Index1])-6),[Index1]) )) return MINX(FILTER(_table2,[Date]=EARLIER(Table1[Date])),[Index1]) - MINX(FILTER(_table2,[Date]=EARLIER(Table1[Date])),[Index2])3. Result:

I cna split these into two table expressions easily, but cannot find a way to index them so that the first
populated row of column 2 gets subtracted by the first populated row of column 1. It wants to use the Date column as the index or filter to line up the equation.
