CALCULATE between dates and parameters

[Guille2711410]

Hello I want to calculate a value between 90, 120, 150 and 180 days. I use the following DAX formula: For example for 90 days it is: Accum_90days = CALCULATE ([M_Value], DATESBETWEEN (Calendar [Date], date (2020,9,30), date (2020,11,30)))

However, I want to change the fixed dates to dynamic dates and that those dates are always greater than my cutoff date of the data DATE CUT.

Calendar [Date]> CUT DATE

How can I do. I will appreciate your comments.

Regards

try:

Accum_90days = 
var _cutoff = [CutDate]

RETURN

CALCULATE (
   [M_Value], 
   DATESBETWEEN (Calendar [Date], 
      _cutoff - 90, 
      _cutoff
     )
)

Thanks Steve

My cut-off date 08/31/2020

I want to calculate the value in the next 90,120,150 and 180 days from the first day of the following month, in this case 09/01/2020 and from there accumulate the value for the next 90 days 11/30/2020.

Also if there would be the possibility of handling the number of days in the same formula.

Thank you very much
