Calculate Retention Rate for two dates

[power_roboter]

Hi team,

I want to calculate the number of users that were active at date a and date b.

In this example the distinct number of users should be 2.

How can I calculate that with dax?

The following is my initial situation:

Date A -> 15.04.2020

UserId

A

B

C

Date B -> 08.04.2020

UserId

Z

A

B

V

Here you are - file attached. Works also with multiple selections of dates in both calendars.

@power_roboter  Can you provide a sample data set. Are you capturing dates in a different tables or the same table?

I have a column with UserIds (unique) that has a connection to a date table. So I can filter the userids for a specific day. Now I want to filter the userids for two days and calculate which users were active on both days.

@power_roboter   - User will select always two days or multiple days?
