Simplifying Date Intelligence with DAX and Calculated Tables

In addition to the M query transformations described earlier in this chapter, DAX table functions can also be used in Power BI Import mode models to enhance and simplify date intelligence. DAX queries can access existing tables in the data model, and the tables evaluated during refresh can be used in relationships and measure calculations like all other tables.
