Academic Calendars

The academic calendar of Washington University in St. Louis is designed to provide an optimal amount of classroom instruction and examination within a manageable time frame, facilitating our educational mission to promote learning among both students and faculty.

Beginning in the Fall 2016 semester, our Fall Break became a four-day weekend with no classes on a Saturday through Tuesday in mid-October.  This decision was made by the Academic Calendar Committee, approved by the Provost and announced to the university community in April of 2014. This calendar change brought our Fall semester’s instruction days in line with Spring, in that both now include a full calendar week without classes (the new Fall Break and the Thanksgiving Holidays in the Fall, and Spring Break in the Spring) plus one additional Monday without classes (Labor Day in the Fall and the MLK Holiday in the Spring).

Plan ahead and enjoy!

Spring Break 2020 has been extended until March 23 due to the coronavirus (COVID-19) outbreak.

The academic calendar committee is appointed annually by the Provost. Committee members include representatives from each school; the chairperson of the committee is the University Registrar. New academic calendars are generally established in the spring, four years in advance of the current academic year.
