Clemson Academic Calendar 2025‑2026: Important Dates

The Clemson Academic Calendar 2025‑2026 compiles every important date, from Clemson semester dates and enrollment deadlines to tuition payment due dates, course add/drop windows, and final exam schedules.

Clemson University follows a classic semester system: Fall (late August to early December) and Spring (mid-January to late April), plus an optional Winter Intersession (3 weeks in early January) and a Summer Session (12 weeks from May through July, with accelerated modules).

Students can see when tuition is due, when to pick up their schedules (during Pre‑Registration Week), and how to avoid academic penalties by meeting add/drop and withdrawal cut‑offs.

Whether you’re calculating how many credits you can take per semester, checking the Clemson exam schedule, or marking Commencement and Convocation dates, the Clemson University Academic Calendar 2025‑2026 is your go‑to guide for a smooth, successful year at Clemson University.
