In the right-hand sidebar of the Announcements blog you will see a Countdown Clock. This counts down the time left until this class is over on Friday, December 6. Here is a detailed class calendar. There is not a final exam in this class, so we're all done on the very last day of classes; finals then start on Monday, December 9.
The Countdown Clock is a "Google Gadget," which means it is a javascript that you can add to a blog or a webpage where javascript is accepted. If you want to create your own Countdown Clock, here is the Google Gadget webpage where you can configure the specific settings.
