Holidays, Observances and Religious Holy Days
Saint Louis University provides a calendar of holidays, observances and religious holy days — sourced from Jesuit Resource — for informational purposes. To learn more about which days SLU is formally closed or class is not in session, please view the University's holiday calendar and the University academic calendar.
The following definitions, also sourced from Jesuit Resource, should be considered when reviewing the calendar.

Meaningful: Days marked as meaningful are not work-restricted by definition but may be particularly significant to people attending or working at Saint Louis University.

Work-Restricted: Days denoted as work-restricted are recognized denominational sacred or holy days where religious beliefs, laws/doctrines, tenets, canons or theology restrict or limit work (be it physical or mental). This definition may include academic examinations, classroom activities and research or out-of-classroom learning experiences.
