Changing a link according to the date

[admin]

I need a script that may change the link daily. for example one day the link would be

<!-- m --><a class="postlink" href="http://www.------.com/2003/01/14/yazar.htm">http://www.------.com/2003/01/14/yazar.htm</a><!-- m -->

the other day

<!-- m --><a class="postlink" href="http://www.------.com/2003/01/15/yazar.htm">http://www.------.com/2003/01/15/yazar.htm</a><!-- m -->

please help me find a script that does this. I don't have much experience with javascript.
