title: Rotate element every three weeks
body: <p>I'm looking for either a classic asp or a javascript solution for this:</p>
  
  <p>We want something on our webpage that rotates on a three week basis.</p>
  
  <ul>
  <li>Week One: Display A</li>
  <li>Week Two: Display B</li>
  <li>Week Three: Display C</li>
  <li>Week Four: Display A</li>
  <li>Week Five: Display B</li>
  <li>Week Six: Display C</li>
  <li>and so on..</li>
  </ul>
  
  <p>I figure I can do two arrays, one like $Weeks [1,2,4,5,6,7,8... 52] and another like $DISPLAY [A,B,C,A,B,C,A,B... C], both having 52 items, grab the current week and make sure the count on the second array matches the first, but wondered if there's something more efficient? Also, I would have to reset this at January 1st and I'd rather it continue rolling.</p>
  
  <p>Thanks,
  Maureen</p>
