UC Davis Academic Calendar 2026: Comprehensive Guide To Quarters, Deadlines, And Campus Events

Navigating the complexities of a Tier-1 research institution requires precise chronological planning. The UC Davis calendar for 2026 serves as the foundational roadmap for students, faculty, and administrative staff across the Davis and Sacramento campuses. This guide provides an authoritative breakdown of the 2025-2026 and 2026-2027 academic cycles, administrative milestones, and specialized schedules for professional schools.

While the primary search intent for the UC Davis calendar typically revolves around undergraduate academic dates and registration deadlines, this resource also addresses the distinct scheduling requirements for UC Davis Health (Sacramento) and the professional schools of Law, Medicine, and Veterinary Medicine to ensure comprehensive coverage.

Master Academic Schedule for 2026: Quarters and Breaks

UC Davis operates primarily on a quarter system, characterized by high-intensity 10-week instructional periods followed by a final examination week. The 2026 calendar year transitions from the mid-point of the 2025-2026 academic year into the beginning of the 2026-2027 cycle.

Academic progress at UC Davis is governed by the Academic Senate and the Office of the Registrar. It is vital to distinguish between "Instruction Begins" and "Quarter Begins," as the latter often involves administrative preparations, residence hall openings, and faculty meetings before students enter the lecture halls.

Strategic Registration and Administrative Deadlines

Success at UC Davis is often a matter of adhering to strict administrative windows. The 2026 registration cycles are managed through the OASIS (Online Advising Student Information System) and Schedule Builder platforms.

Registration Appointment Windows

Registration occurs in two primary phases known as Pass 1 and Pass 2. During Pass 1, students are limited to 17 units to ensure all students have access to core requirements. Pass 2 allows for unit increases (up to 28.5 units) and waitlist entries.

Expert Insight on Registration Strategy Senior academic advisors recommend that students finalize their primary major requirements during the first 48 hours of their Pass 1 appointment. For 2026, those seeking to graduate in the Spring must ensure their "Candidacy for Graduation" is filed via OASIS by the end of the second week of the Winter Quarter to avoid late processing fees and potential commencement delays.

Critical Drop and Grading Deadlines

• 10-Day Drop Subjects: For high-demand courses (often in STEM and impacted majors), the deadline to drop without a "W" is typically the 10th day of instruction.
• 20-Day Drop Subjects: Most other courses allow for a 20-day window.
• P/NP (Passed/Not Passed) Option: In 2026, the deadline to change grading options to P/NP remains the end of the 25th day of instruction. It is imperative to consult with college-specific advisors (CAES, CBS, COE, or L&S) before selecting this option, as it may impact major requirements or graduate school prerequisites.

Professional Schools: Law, Medicine, and Veterinary Medicine

Unlike the undergraduate "Davis Campus" schedule, the professional schools often operate on a semester or modified annual calendar.

1. UC Davis School of Law (King Hall): Typically follows a semester system. The Spring 2026 semester begins in early January, with finals concluding in mid-May. The Fall 2026 semester commences in mid-August.
2. UC Davis School of Medicine (Sacramento): Features a highly customized clinical rotation schedule. Third and fourth-year medical students do not follow the standard academic holidays, as their schedules are dictated by hospital shift requirements and patient care cycles at the UC Davis Medical Center.
3. School of Veterinary Medicine: Often utilizes a modified quarter system that aligns closely with the main campus but includes extended clinical rotations during the summer months.

UC Davis Health: Clinical and Patient Calendars 2026

The UC Davis Health calendar focuses on clinical operations at the Sacramento campus and various regional clinics. This system operates 24/7/365, but administrative and non-emergency outpatient services follow a specific holiday schedule.

• Network Status: UC Davis Health remains a premier provider in Northern California, accepting most major insurance plans including Western Health Advantage, Blue Shield of California, and UnitedHealthcare.
• Medicare Requirements: UC Davis Health accepts Original Medicare and many Medicare Advantage plans. However, patients enrolled in HMO-style plans must have an assigned Primary Care Physician (PCP) within the UC Davis Medical Group to access specialist services without out-of-network costs.
• Operational Closures: Outpatient clinics located in Davis, Roseville, Folsom, and Elk Grove will be closed on major federal holidays including New Year's Day (Jan 1, 2026), Independence Day (July 4, 2026), and Christmas Day (Dec 25, 2026).
