one way they could make it user-variable is to strip out the parts of the html source that declare the table attributes as separate css page.  these are the modules including:

<<span class="start-tag">span</span><span class="attribute-name"> id</span>=<span class="attribute-value">"countdown671315194" </span>><br></br><<span class="start-tag">table</span><span class="attribute-name"> style</span>=<span class="attribute-value">"background-color:#007cad;" </span><span class="attribute-name">class</span>=<span class="attribute-value">"countdown_671315194"</span>><br></br><br></br>where javascript uses countdown from "time zero" IIRC, so we know what day it is.  <br></br>but maybe that's why they can't separate it out - the javascript.
