How to set a css class to a day containing an event in jquery Fullcalendar

I have a Fullcalendar implementation at: http://seattledesigndistri开发者_StackOverflow中文版ct.com/events/ Overall it works pretty well, I am still cleaning it up in the different browsers, but the thing works pretty well with my custom post type in WP.

The issue is that I would like to set add a css class to a day's <td> if there is an event inside of it. The issue that I can see, so far, is that the events aren't even contained in the td, they are absolutely positioned inside it.

Any ideas how to get this done easily? I am open to a small jQuery script as well... Just trying to hammer out a solution.

thanks
