title: DAX: Subtract X Years/Days/Months from NOW()
body: <p>I'd like to create a dynamic date table, the date range is NOW - 3yr to NOW.  How is this done in DAX?</p>
  
  <p>I know how to use the calendar function, and have used the MIN and MAX on a table of invoices to get the start/end dates, but now need to get the current date -3 years.  </p>
