Nice article as a launching point for people just jumping into DAX.
I do have a few questions, though..
Under the Date & Time section, was the month portion of the DAX typo'd (says "year")?
ROW ( "First Year" , Year(Date(1900,1,1)),
"First Month", Year(Date(1900,1,1)),
"First Day", Day(Date(1900,1,1)) )
Also, the DAX directly below that one for some date arithmetic seems to be spelled incorrectly?
ROW ( "One month previous" ,eDate(now() ,-1) )
I don't have a DAX window open in front of me, but just some observations from reading the article. Again- great for beginners trying to correlate what they know with what they're trying to learn!
