Every Power BI model has dates and the need for calculation over dates to aggregate and compare data, like Year-To-Date, Same-Period-Last-Year, Moving Average, and so on. Quick measures and standard time intelligence functions in DAX can help, but how do… Watch now

DAX provides a set of functions (Time Intelligence) to compute aggregations and comparisons over a range of dates: Year-To-Date, Same-Period-Last-Year, Moving Average, and so on. The DAX time intelligence functions can work well with a month granularity, but they have… Watch now

In this article we demonstrate how to use calculation groups to show the behavior of any measure in the last 6 months, starting from a single date selection with a slicer. This can be applied to any number of months. Read more

Rolling averages over time (a.k.a. moving averages or running averages) are useful to smoothen chart lines and to make trends more evident. This article shows how to compute a rolling average over 12 months, in DAX. Read more
