title: Getting current date in JSTL EL and doing arithmetic on it
body: <p>Without using scriptlets, what's the correct way for doing date arithmetic in JSP?</p>
  
  <p>Here are examples what I'm trying to do:</p>
  
  <ol>
  <li>Get current year (YYYY)</li>
  <li>Subtract current year by one to get previous year (YYYY)</li>
  </ol>
  
  <p>Thanks!</p>
