DAX for Power BI videos | DAX for Power BI Part 6.1 - Introduction to Time Intelligence Functions

Posted by Andrew Gould on 15 January 2022


This video shows you how to get started with time intelligence functions in DAX. You'll learn how to make Power BI create a date table for each date column in your data model automatically. You'll also learn what the auto date table contains and why it's important for the operation of the time intelligence functions. You'll see how to display different levels of a date hierarchy and how to use the DateAdd function to modify the filter context applied to a measure to compare a calculation with past and future dates. Finally, you'll learn how to use the SamePeriodLastYear function as a shorthand for a specific use of the DateAdd function.
