Reading Day
From U of I Wiki
Reading Day is the day before the university's week of final examinations each fall and spring semester. The day's purpose is to afford all students some time to spend studying for the finals in the coming week.
Reading Day in the fall semester is the Saturday prior to finals week, and in the Spring semester, is the Thursday prior to finals week starting on Friday.
The day before Reading Day is the last day of classes and is a popular night to go to the bars in Campustown.
