UC Davis operates on a semester‑based calendar, beginning each academic year with a Fall session that starts in early September and ends in mid‑December, followed by a Spring session that runs from late January to early May. The summer offers optional courses and research opportunities, while the winter break provides time to rest or engage in internships. Understanding this framework is essential for aligning registration, coursework, and graduation plans.
Key dates punctuate this calendar: the Registration Open Day typically falls in the first week of August, followed by a 48‑hour deadline for course enrollment. Fall and Spring class cancellation deadlines are set five days before classes begin. Academic progress must be reported quarterly, and the graduation application window opens in September of the senior year. Staying aware of these dates ensures timely course selection and compliance with university requirements.
