UMass Academic Calendar 2025‑2026: Important Dates

The UMass Academic Calendar 2025‑2026 schedule contains all the essential dates from UMass enrollment and registration deadlines, tuition payment due dates, and course add/drop periods to university holidays and final exam schedules.

The University of Massachusetts academic calendar helps you stay ahead of UMass term dates, plan around the UMass exam schedule, track UMass add/drop deadlines, and never miss the last day to withdraw without a “W,” ensuring seamless academic and financial planning at UMass.

UMass Amherst follows a structured academic year with both full‑term semesters and shorter intersessions:

• Fall & Spring Semesters: each spans approximately 15 weeks (14 instructional weeks plus one week of finals)—so if you’re asking how long a semester is at UMass, expect about three and a half months of classes and exams.
• Winter Intersession: a 3‑week intensive session in January for accelerated or makeup courses, perfect if you need to catch up or get ahead.
• Summer Sessions: broken into Session A and Session B (each about 6 weeks) plus a Full Summer Session (around 12 weeks), each with its own registration, add/drop, and billing deadlines—ideal for flexible, accelerated study.

Whether you’re mapping out your 15‑week semester course load, squeezing in a 3‑week Winter Intersession class, or choosing the right Summer Session module, the UMass Academic Calendar 2025‑2026 is your go‑to guide to every date and deadline you need to thrive at the University of Massachusetts.
