DAX: Date Calculation Tables

Some time ago, I blogged about using a date calculation dimension in a multidimensional cube, and how easy it makes doing time intelligence in a multidimensional model. 2014 seems to have started out as "the year of Power Pivot", as it is definitely gaining traction with my clients and more and more of them are asking about it during engagements. One of the absolutely amazing things I get absolutely giddy about in Power Pivot is the concept of disconnected slicers. As Rob Collie best said, disconnected slicers in Power Pivot are pure magic. I particularly enjoy the "mad scientist" reference he makes. For those unfamiliar, a disconnected slicer is a piece of data that has absolutely nothing to relate to in your data, but you want to use it as a part of your analysis. For a great introduction, see Rob's Power Pivot pro blog about it as an introduction. I was recently showing a client this mad scientist level stuff, but then took the natural progression and thought: "If I can do this to control the number of months back, can I take it a step further and create a date calculation dimension like in multidimensional too?" What, that wasn't the first thing you thought too?
