And few measures

This Month =
var _max = eomonth(if(isfiltered('Date'),MAX( 'Date'[Date]) , today()),0)
var _min = eomonth(_max,-1)+1 ,
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

Last Month =
var _max1 = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _max = eomonth(_max1,-1)
var _min = eomonth(_max1,-2)+1
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

Rolling 2 =
var _max = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _min = Date(Year(_max), month(_max) -2, Day(_max))+1,
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

rolling 3 =
var _max = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _min = date(Year(_max), month(_max) -3, Day(_max))+1
BLANK())
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

or

rolling 3 =
var _max = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _min = eomonth(_max,-3)+1
BLANK())
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))
