This is on the page that tells me when I can register:

Registration/Add-Drop Access Schedule

Spring Semester 2009

Jan 23 - Feb 4. You may long in the system only to look at your
classes. Any changes to those classes must be done in the
department offering the class. The system is open during this
time from 8a-12m except Jan 4 when it closes at 5p.
