UB Academic Calendar 2026-2027: Important Dates & Deadlines

The UB Academic Calendar 2026-2027 contains all the dates from application and enrollment deadlines, tuition payment due dates, and course add/drop windows to campus holidays and final exam schedules.

University at Buffalo’s academic year follows a traditional semester system enhanced by an optional Winter Intersession and flexible Summer Sessions:

• Fall and Spring Semesters each span about 15 weeks (14 instructional weeks plus one week of finals).
• Winter Intersession offers a short, 3‑week intensive term in January for makeup or accelerated courses.
• Summer Sessions come in three formats—Session I (5 weeks), Full Summer Session (12 weeks), and Session II (7 weeks), each with its own registration, add/drop, and fee‑payment deadlines to fit your schedule.

Whether you’re mapping out a full‑semester course load, squeezing in a Winter Intersession intensive, or choosing the right Summer Session module, the UB Academic Calendar 2026-2027 is your go‑to guide to every date and deadline you need to thrive at the University at Buffalo.
