var _last=CALCULATE(SUM('Table'[number1]),FILTER(ALL('Table'),'Table'[Date]=DATE( YEAR(EARLIER('Table'[Date]))-1,MONTH(EARLIER('Table'[Date])),DAY(EARLIER('Table'[Date])))))
return

Hello, you mean the calendar date that I use as "date" reference in my Power BI ? 

Calendrier =
ADDCOLUMNS(
CALENDAR(DATE(2019,01,01), TODAY()),
"Année" , year([Date]),
"Année Trimestre", Year([Date]) & "-Q" & Format([Date], "q"),
"Année Mois" , FORMAT([date],"YYYY MM"),
"Num Mois", FORMAT ( [Date], "MM" ),
"Mois", FORMAT([date],"MMMM"),
"Semaine", WEEKNUM([Date]),
"Trimestre", "Q" & FORMAT ( [Date], "Q" ),
"YearMonthShort", FORMAT ( [Date], "YYYY/mmm" ),
"MonthNameShort", FORMAT ( [Date], "mmm" ),
"DayOfWeekNumber", WEEKDAY ( [Date] ),
"DayOfWeek", FORMAT ( [Date], "dddd" ),
"DayOfWeekShort", FORMAT ( [Date], "ddd" )
)

      number2   = CALCULATE(SUM(MyTable[number1]), PARALLELPERIOD('Calendrier'[Date],( ( 2019 - year(MyTable[Date]) ) * 12) ,MONTH) ) is giving the same result ... only resylts for 2019 dates !!! 
       
      and when I try 
      number2   = CALCULATE(SUM(MyTable[number1]), PARALLELPERIOD('Calendrier'[Date],( ( 2019 - year('Calendrier'[Date]) ) * 12) ,MONTH) ) ... I have power bi error saying too many values in Calendrier ...
