About Conformed dimensions

Hi experts,
As mentined in Toolkit, Dimensions also conform when they contain a subset of attributes from a more granular dimension. However, I have a question about this topic.
I have a dimention A like date, week, month, quarter, year. Then, I wonder if a dimension B like week, quarter is the conformed with dimension A. Could you please help to clarify it?

Basically all it means is, if you have a date and week dimension, the attribute values are the same for the same time period. Attributes for week, fiscal period, year, etc should be the same in both tables. It does not mean that all attributes are represented, For example, it would be unusual to have month attributes in a week dimension.
