Hi CahabaData,
Based on you description, you want to know whenever you need to use a date table, right?
If as I said, you can refer to below scenarios which you need to use date table:
1. many to many relationship.
If you have two tables both contain many duplicate date records and you want to create relationship between them, you should add a date table to link them.
2. Get specify date between start date and end date.
Sample: get the weekend from 2010 to 2015.
3. Use a slicer to filter multiple tables(contain date field).
>> the hidden automatic Date table and it automatically joins to all tables/fields that have a date field type...
You have a misunderstanding of the hidden table, the hide table is created by time intelligence feature, the hide table(date hierarchy) is analysis by date field, it only related to the column which used to create the table, not automatically joins to all tables/fields that have a date field type.
In addition, you could work through ‘Scenario 1’ without create a date table , the time intelligence feature is enable on the newest version of power bi desktop(2.38.4491.282).
