Every Thursday, a website I link to creates a new webpage of discounts. For example, today is Thursday June 23, so the filename is 2005-06-23.html.
What I want to do is to change the link on my page to automatically update when it is Thursday so that it is <a href="http://www.otherwebsite.com/discounts/2005-06-23.html">link</a>
and next Thursday it would be
and so forth.
