    mariner84 ,

     

    Not very clear about your requirement. But generally, I suggest you to create a calendar table using dax and build relationships between the three tables because simply merging tables together will slow down the performace of power bi. You can create slicer based on the created calendar table if you have one-many relationship between calendar and these tables.
