title: Start Sharepoint workflow "x" days before expiry date
body: <p>I want to create a workflow on a Sharepoint list and it should send a notification email. </p>
  
  <p>The problem is that I want this workflow based on expiry date(send an email 30 days before the expiry date) and I am not creating or updating any new list items. </p>
  
  <p>I know workflow can only be created if any item are changed/created but I have seen some buzz around on the net that this can be possible using SPD.</p>
  
  <p>Any suggestions would really be appreciated.</p>
  
  <p>Thanks,</p>
