Religious Observances that Affect the Academic Calendar

Candles line the paths of the main quad as part of a Diwali celebration. The dome of Foellinger Auditorium is lit. Several people are in silhouette.

To help instructors and staff in course and event planning, some of the religious observances that may affect the academic calendar between August 2022 to July 2023 are listed below. This table attempts to include dates for religions that are most widely observed by students and employees at the University of Illinois and is intended as an aid only. Members of the University of Illinois community practice a range of faith traditions, and it is the expectation of the university that religious accommodations be honored regardless of whether the date is included in this table.

Special thanks to the following individuals for their assistance in reviewing the religious observances listed on this page and in the full Religious Observances calendar: Rabbi Alan Cook from Sinai Temple of Champaign-Urbana, Amy Felty from the Spiritual Assembly of the Bahá’ís of Urbana, Father Robert Lampitt from St. John’s Catholic Newman Center, Dr. Adam Newman from the Department of Religion, and Imam Ousmane Sawadogo from the Central Illinois Mosque and Islamic Center.
