Creating a relationship between date table and data table

[DaniBran1]

Is there a way I can create a relationship between these 2 tables: 

Currently the data has the header as months but the data underneath are scores: 

I am trying to create a visualization that will show scores by month for each property.

Thank you for your assistance!

I'd strongly recommend unpivoting your data table.

Then convert the month names into dates (e.g. "Apr" --> 4/1/2023) for the appropriate year so that you can create a relationship to Calendar.
