UIUC Academic Calendar 2025‑2026: Important Dates

The UIUC Academic Calendar 2025‑2026 brings together every essential date from application and enrollment deadlines, tuition payment due dates, and course add/drop periods to campus holidays and final exam schedules.

The University of Illinois Urbana‑Champaign academic calendar helps students to lock in UIUC semester dates, plan around the UIUC exam schedule, track UIUC registration deadlines, and never miss the last day to withdraw without a “W,” ensuring smooth academic and financial planning at UIUC.

UIUC follows a traditional semester system enhanced by flexible summer offerings:

• Fall and Spring Semesters: each spans approximately 15 weeks (14 instructional weeks plus one finals week), giving you time for lectures, midterms, and finals.
• Winter Break: a multi‑week pause between fall and spring, perfect for recharging or handling independent study projects.
• Summer Sessions: divided into Session I and Session II (each roughly 6 weeks) and a Full Summer Session (about 12 weeks), each with its own add/drop and payment deadlines for accelerated or makeup courses.

Whether you’re mapping out your 15‑week semester course load, budgeting for UIUC semester fees, or choosing the right summer session at UIUC, the UIUC Academic Calendar 2025‑2026 keeps all your key dates and deadlines at your fingertips so you can focus on thriving at the University of Illinois.
