If you search for "Academic Calendar" on the UC Berkeley website, you'll get a link that looks promising. When you actually choose the calendar to view, you'll be surprised to see that it contains only a few items like holidays, class start dates, and final exam days. How do you find out the last day to drop or withdrawl or other juicy academic tidbits? You need this rather pimped out 2006-2007 Calendar.
Big ups to the College of Letters and Science's advising department for putting together this mega list of important dates.
