Create rolling Calendar Table

I am trying to create a Calendar Lookup table that will connect to a data table containing dates from TODAY going back 40 days. The idea is I only need say 40-50 days in the Calendar Lookup table rather than have this table accumulate additional rows that will not be utilized.

 

Has anyone had any luck in creating such a dynamic table and could shed some light on the best way to go about this please?

You can create a table as follows

 

Calendar 40 Days = 

CALENDAR(TODAY() - 40,TODAY())


But I would recommend creating a complete calendar table as it will be useful to utilize all the time intelligence functions and mark it as date table for better modeling.

Here is the code for the full dates table:

Dates = 
ADDCOLUMNS(
    CALENDAR("01/01/2013","31/12/2015"),
    "Month", MONTH([Date]),
    "Month Name", FORMAT([Date],"Mmmm"),
    "Year", YEAR([Date]),
    "Year Month No", YEAR([Date]) * 100  + MONTH([Date]),
    "Year Month" , FORMAT([Date] , "Mmm yyyy" )
)
