Aligning a vertical list horizontally

I have a little vertical list that I want to align horizontally. Problem is it's not really a list (per tag def.). Since the "list" is created by WebCalendar, I can't (and won't hack it), so I need to find some way to align it by the dd and dt tags used. I think the two links below will help you understand what I mean:)

Here is the list (check source for code): http://sagavoll.com/kalender/upcoming.php
And this is how I want it to look: http://sagavoll.com/kalender/yep.php

Any takers? Suggestions?
