Academic Calendar
The Cornell academic year follows a semester system, consisting of a fall and a spring semester, both of which include a final exam week. Each semester must be a minimum of 14 weeks of instruction, yet must combine in fall and spring to a minimum of 30 weeks of instruction. Instructional periods/terms include fall, winter intersession, spring, and summer. In all academic terms, variable-length, short-session courses are available, and meet the same total contact (class) hours as in a standard semester. See the policy on Defining and Assigning Credit Hours for additional information.
The university bylaws define the academic year as the approximately nine-month period beginning two working days before registration in the fall term and ending on the last day of final examinations in the spring term.
The summer period is defined as the period between the last day of one academic year and the first day of the following academic year. Summer courses carry full credit because classes meet the name number of contact hours as in the standard fall or spring semester.
For the current Academic Calendar and other important dates, see Key Academic Dates on the University Registrar's website.
