How to identify a date that doesn't exist in a fact table ?

[Anonymous]

I am trying to solve a issue with dates, let me explain:

I have a calendar date and a fact table (checking table) where people check your entry, so the only records that exists is when the person check if the person don't check the record don't exists, the questions is, how can I identify the dates that aren't in the fact table.  

example of fact table: in this example employee 'A' didn't check on 08/17/20 and Employee 'C'  08/18/20. 

Employee	date
A	08/16/20
A	08/18/20
A	08/19/20
B	08/16/20
B	08/17/20
B	08/18/20
C	08/16/20
C	08/17/20
C	08/19/20

Note: My calendar table has a relation with the column date. fact table (Date) -> Calendar table (Date)

I will appreciat if  you can help me with this issue

Thank you

With isempty works, I put a 0.

Now I am no t able to count the 0s, do you have some idea. it is not counting because is a result of a measure.

Hi @Anonymous,

I'd like to suggest you use except function to compare between fact table date and calendar date, then you can simply get these not include date values list.
