title: Last 12months & next 4months with DAX
body: <p>I have a date table with a date column. I would like to add a column which returns YES for dates that are in: <strong>Last 12 months &amp; next 4 months</strong></p>
  
  <p>I need to build this column with a DAX formula and directly in Power BI desktop, so "not" in the power query with M language.</p>
  
  <p>Thank you very much in advance!</p>
