Navigating the university's schedule requires precision, especially under a fast-moving quarter system. The UC Davis academic calendar 2025-2026 outlines all instructional periods, registration windows, fee payment cutoffs, and official holidays across the fall, winter, spring, and summer terms. Missing a single deadline can result in late fees, dropped classes, or blocked enrollment privileges, making proactive planning essential for undergraduate and graduate students alike.
Official term dates span from September 2025 through June 2026, structured to give students roughly ten weeks of instruction per quarter followed by final examinations. Whether you're tracking add/drop periods, fee deadlines, or commencement ceremonies, understanding how the academic year unfolds helps you balance coursework, financial aid, and personal commitments without last-minute panic.
Fall Quarter 2025 Schedule and Deadlines
Fall quarter marks the beginning of the academic year, bringing incoming freshmen, transfer students, and returning upperclassmen back to campus. Instruction for this term officially commenced on Wednesday, September 24, 2025, following move-in week and mandatory orientation events.
- Quarter Begins: Monday, September 22, 2025
- Instruction Begins: Wednesday, September 24, 2025
- Veterans Day Holiday: Tuesday, November 11, 2025 (no classes)
- Thanksgiving Holiday: Thursday, November 27 and Friday, November 28, 2025
- Instruction Ends: Friday, December 5, 2025
- Final Examinations: Monday, December 8 through Friday, December 12, 2025
- Quarter Ends: Friday, December 12, 2025
Registration for fall courses typically takes place during the preceding spring phase, with open registration and schedule adjustments continuing through September. Students must finalize their study lists through UC Davis OASIS before university-mandated deadlines to avoid late transaction fees.
Winter Quarter 2026 Key Dates
Winter quarter brings shorter days and an intense academic pace right after the winter closure. Because the term starts immediately after New Year's Day, students must handle housing arrangements and textbook acquisitions well in advance.
- Quarter Begins: Friday, January 2, 2026
- Instruction Begins: Monday, January 5, 2026
- Martin Luther King Jr. Day: Monday, January 19, 2026 (observed holiday)
- Presidents Day: Monday, February 16, 2026 (observed holiday)
- Instruction Ends: Friday, March 13, 2026
- Final Examinations: Monday, March 16 through Friday, March 20, 2026
- Quarter Ends: Friday, March 20, 2026
Winter break offers a brief window for rest, but it's also when fee payment deadlines for winter quarter take effect through UC Davis Student Accounting. Failing to pay tuition fees on time triggers registration holds that can drop students from their enrolled sections.
Spring Quarter 2026 Milestones
Spring quarter features warmer weather, Picnic Day events, and the final push toward the end of the academic year. Instruction starts following a brief spring break that overlaps with late March holidays.
- Quarter Begins: Thursday, March 26, 2026
- Instruction Begins: Monday, March 30, 2026
- César Chávez Holiday: Friday, March 27, 2026
- Memorial Day: Monday, May 25, 2026 (observed holiday)
- Instruction Ends: Thursday, June 4, 2026
- Final Examinations: Monday, June 8 through Thursday, June 11, 2026
- Quarter Ends: Thursday, June 11, 2026
- Commencement Ceremonies: Friday, June 12 through Sunday, June 14, 2026
Graduating seniors must pay close attention to graduation application deadlines earlier in the quarter. Missing the filing window can delay degree conferral and official diploma distribution.
Essential Registration and Fee Deadlines
Staying on top of administrative milestones prevents disruptions to your financial aid and class schedule. Every quarter follows a strict sequence of registration phases managed via UC Davis Schedule Builder.
- Phase 1 Registration: Usually occurs mid-quarter for the upcoming term, allowing students to build their primary schedules based on class standing.
- Phase 2 Registration: Opens later in the quarter, letting students adjust units, add backup courses, and address waitlists.
- Fee Payment Deadline: Generally set a few weeks before instruction begins. If financial aid disbursement is delayed, students must check with the Financial Aid and Scholarships Office to prevent fee cancellation.
- Add/Drop Deadlines: The first two weeks of instruction allow free schedule adjustments. After the second week, drops require a late fee, and by week six, dropping a course typically results in a "W" grade on the transcript.
Common Planning Mistakes to Avoid
Managing a demanding course load across ten-week terms leaves little room for organizational errors. Keep these pitfalls in mind as you plan ahead:
- Ignoring the Fee Payment Calendar: Many students assume financial aid covers everything automatically. Always verify your zero-balance status on MyBill before the fee deadline.
- Waiting Until Phase 2 for Mandatory Core Classes: Popular major requirements fill up quickly during Phase 1. Missing your assigned registration pass time can push graduation back by a full year.
- Overestimating Available Time: Taking four heavy STEM classes in a single quarter often leads to burnout. Balance rigorous technical courses with general education requirements.
- Missing Pass/No Pass Deadlines: Changing grading options requires submitting requests before strict university cutoff dates, usually around the midpoint of the quarter.
Frequently Asked Questions
How do I check my specific registration pass time for upcoming quarters?
Log into your UC Davis MyUCDavis Portal and navigate to Schedule Builder. Your exact appointment window appears prior to Phase 1 and Phase 2 registration periods based on your earned units and class level.
What happens if I miss the fee payment deadline?
Missing the payment deadline results in a late fee of up to $50 and can trigger cancellation of your enrolled classes. If this happens, you must re-register during open periods, subject to seat availability.
How are final exams scheduled during the quarter?
Final exams take place during the final week of each quarter. Instructors follow the official university final exam schedule based on the meeting time of the class. Check your syllabus during week one to avoid travel conflicts.
Can I drop a class after the quarter's instruction ends?
No. Once final examinations begin, courses cannot be dropped through standard web registration. Exceptional circumstances require a late petition through your college's advising office.
