UCR Academic Calendar 2025‑2026: Important Dates

The UCR Academic Calendar 2025‑2026 brings together every crucial deadline you need from application and enrollment cut‑offs, tuition payment due dates, and course add/drop windows, to campus holidays and final exam schedules.

By consulting the University of California, Riverside academic calendar, students can stay ahead of UCR term dates, track UCR registration deadlines, plan around the UCR exam schedule, and never miss the last day to withdraw without a “W” or the start of Summer Session fee payment deadlines.

UCR operates on a four‑quarter system:

• Fall Quarter: late September to mid‑December (10 instructional weeks + 1 week of finals)
• Winter Quarter: early January to mid‑March (10 instructional weeks + 1 week of finals)
• Spring Quarter: late March to early June (10 instructional weeks + 1 week of finals)
• Summer Session: mid‑June to mid‑September, divided into Session A (6 weeks) and Session C (6 weeks) with separate add/drop and fee deadlines

Whether you’re mapping out a 10‑week quarter load, fitting in a 6‑week Summer Session course, or budgeting for per‑quarter tuition, the UCR Academic Calendar 2025‑2026 is your go‑to guide for all the dates and deadlines you need to thrive at UCR.
