Important Dates & Deadlines
Session Calendars
Summer Session, which runs from May to August each year, is composed of eight independent academic sessions. The add/drop process in summer works the same as in fall and spring; however, the time frame to take action in summer is much shorter. These important academic and financial dates vary by session, so make sure you are familiar with the dates and deadlines for the session(s) you plan to enroll in.
If you have questions about the enrollment, add/drop or withdrawal deadlines for a specific session, contact the Office of the Registrar at registrar@colorado.edu or 303-492-6970.
If you have questions about payment deadlines, call the Bursar's Office at 303-492-5381 or stop by the office, located on the first floor of the Regent Administrative Center.
Academic dates vary by class. Find your specific course(s) under the Variable Sessions calendar on the Office of the Registrar's website for beginning, end and final exam dates, as well as for add/drop dates.
