Working day current month with previous months

[DGFranco77]

I need to create a view where I take the business days of the current month held in sales and compare with the previous months in the first business days as well.

For example, this month... let's assume that today (date of publication of this post) we have 3 working days for the month of September. For the other previous months I need to know in the first 3 working days how much I accomplished.

I have tried several ways, but have not succeeded.
Thank you in advance, whoever can help me.

@DGFranco77 , based on today 

MTD Today =
var _min = eomonth(today(),-1)+1
var _max = today()
return
CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

LMTD Today=
var _min = eomonth(today(),-2)+1
var _max1 = today()
var _max = date(year(_max1),month(_max1)-1, day(_max1))
return
CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

Based on selected vs today

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

LMTD =
var _max1 = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _max = date(Year(_max1), month(_max1)-1, day(_max))
var _min = eomonth(_max1,-2)+1
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))
