    Dicken , I created a table with the same code, and it worked

     

     

    In case of measure use

    Maxx( INDEX(1 , dDate, ORDERBY(dDate[Date]) ), [Date])

    Dicken Try this : 

     use distinct around  the table you are using in window functions

Sorry, just to add did this in power pivot Dax studo, but this is what I would expect index to return, 
a one row  ( top ) table; 

EVALUATE 
 FILTER( 'Calendar', 
  'Calendar'[Date] = DATE( 2020,1,1) 
  )
