UC Davis Academic Calendar 2025‑2026: Important Dates

The UC Davis Academic Calendar 2025‑2026 compiles every deadline and milestone from application and enrollment dates, tuition payment due dates, and course add/drop periods, to campus breaks and final exam schedules.

Referencing the University of California, Davis academic calendar, students can lock in their UC Davis term dates, help you plan around the UC Davis exam schedule, track registration windows, and never miss the last day to withdraw without a “W” or the start of Summer Session fee deadlines.

UC Davis operates on a quarter system:

• Fall Quarter (late September to mid‑December; 10 weeks of instruction + finals week)
• Winter Quarter (early January to mid‑March; 10 weeks + finals)
• Spring Quarter (late March to early June; 10 weeks + finals)
• Summer Session (divided into Summer Session A and B, each 5 weeks, plus a full 10‑week session for accelerated or make‑up courses)

Whether you’re wondering how long a quarter is at UC Davis, when you can enroll, or how to avoid late‑fee penalties, the UC Davis Academic Calendar 2025‑2026 lays out all the critical dates from priority registration deadlines and add/drop cut‑offs to the final exam schedule so you can focus on thriving at UC Davis.
