title: dynamic columns for dates
body: <p>Columns   [today],  [30days ago], [60days ago], [90 days ago]</p>
  
  <p>I have a table the will provide me with the sales number fro today and 30days ago, 60 days ago and 90 days ago,</p>
  
  <p>But the issue I have is to figure out what the actual date was 60 days ago.
  I wanted to update my script not show me 60days ago but to show me the actual date 60days ago. I want to make my columns dynamic so i get the actual date 90days ago.</p>
  
  <p>Can anyone help me here?</p>
  
  <p>Please remember this is a long scripts and 10 columns and I want to change each column to show me the actual date and not the 90 days ago.</p>
