Power BI is an amazing toolbox for understanding data. Most of us are probably familiar with the basics – making charts, creating dashboards, and seeing those key numbers. But just like any good toolbox, there are some hidden gems, some really powerful tools that might not be used as often as they could be.

One such feature that often flies under the radar is “Calculation Groups.”

Now, that might sound a bit technical, but the idea behind it is actually quite clever and can save you a ton of time and effort, especially if you’re working with time-based data.

So likewise I want to know have anyone encountered such feature that is rare or the community is not much familiar with?
