"Academic" refers to service days during the fall and spring semesters, when the university is holding in-person classes.

"Interim" refers to service days during university breaks in an academic session, such as Thanksgiving Break and Spring Break.  It also refers to the winter break period between the end of fall semester and the beginning of spring semester.  Some route schedules change during interim periods, and some routes are suspended.  CAMBUS does not operate weekend service during periods identified as "Interim service".

"Summer" refers to service days operated between the end of the spring semester and the start of the fall semester.  Summer service typically resembles Interim service with some changes.
