Days Between Slicer Dates in Measure

[Anonymous]

Hi, 

I am trying to create a measure the calculates a straigt line average across my slicer range. I am having trouble setting the 'Remaining Days' (from my slicer delta and my last date of sales) for all data points. 

As you can see, when I use my 'Calendar'[Date] (which is my related calendar table) with the [Remaining Days] Measure, it shows -19 for every date point but sums up to the correct value of 345 in this instance which is the delta between 1/1/2019 and 12/31/2019 and my last sales point of 1/19/2019

@Anonymous try something like this, add new column, assuming you have "YEAR" colum in your calendar dimension

Remaining Days = 
VAR y = CALCULATE( MAX( 'Calendar'[Year] ) )
VAR l = CALCULATE( MAX( 'Calendar'[Date] ), ALL( 'Calendar' ), 'Calendar'[Year] = y )
RETURN 
    DATEDIFF( 'Calendar'[Date], l, DAY )

Hi @Anonymous

You may try below measure:

Remaining Days =
VAR a =
    FIRSTDATE ( 'Calendar'[Date] )
VAR b =
    CALCULATE ( MAX ( 'Calendar'[Date] ), ALLSELECTED ( 'Calendar'[Date] ) )
RETURN
    DATEDIFF ( a, b, DAY )
