Single Date Filter for multiple Tables that do no relate.

Hi Dalton948 ,

If I understand you correctly, each of your tables contains a date column, and then you want to filter the data in all the tables by a date slicer.
I recommend that you add an additional Calendar table that contains all the dates covered in the other tables. Then create a relationship between this table and the other tables.
Here is my sample data:

And I use this DAX to create the Calendar table (The date span in my sample data is 2024.1.1-2024.4.10):

Calendar Table = CALENDAR(DATE(2024, 1, 1), DATE(2024, 4, 10))

Then create relationships between these tables:

Use the Calendar Table to create the slicer and the final output is as below:
