Academic Calendar

Each Williams-Mystic semester is 17 weeks. Fall semesters begin late August and end mid-December; spring semesters run from late January through mid-May.

In both the fall and spring semesters, students, staff, and faculty travel together on three interdisciplinary field seminars, including an Offshore Voyage and two land-based trips to the Pacific Coast and the Gulf Coast.

Dates are subject to change. Students will receive a more comprehensive schedule once the semester begins, which will include day trips, class meeting times, and other events.
