DAX for CALCULATE Using a Column with a Date as Filter

[KMcCarthy9]

Hi I have a table that holds a identifier column and a max_eff date column. 

I'm trying to do a simple Calculate formula to obtain a count for all the assetnums that have a max_eff date of 1/1/2021, however every result is returning BLANK. I know the issue if the way I am trying to filter on the max_effect column. Any suggestions? 
I do have the table connected to my date table and have tried using DATE = 1/1/2021 but that also returned BLANK. 

DAX:

2021 Starting Asset Count = CALCULATE(COUNTA('Program Status'[assetnum]), 'Program Status'[max_effdate] = 1/1/2021)

TABLE:

Thanks!

Hi,

One of these should work

2021 Starting Asset Count = CALCULATE(COUNTA('Program Status'[assetnum]), 'Program Status'[max_effdate] = DATE(2021,1,1))

2021 Starting Asset Count = CALCULATE(COUNTA('Program Status'[assetnum]), FILTER('Program Status','Program Status'[max_effdate] = DATE(2021,1,1)))

Hope this helps.
