ILLINOIS — Most public schools across Illinois are scheduled to be closed on Monday, May 25, 2026, in observance of Memorial Day, according to multiple district calendars and statewide guidance.
Memorial Day, observed annually on the last Monday in May, is recognized as a legal school holiday in Illinois. State guidance and district calendars consistently identify the day as a non-attendance date, with schools and offices closed.
Calendar data from numerous Illinois school districts—including those in suburban Chicago and other regions—confirm that May 25 is listed as “No School” or “District Closed” for Memorial Day. In many cases, district offices are also closed, and no student instruction takes place.
For the month of May, Memorial Day stands out as the only broadly observed holiday that results in widespread school closures across Illinois. While some districts may include additional non-instructional days—such as teacher institute days, emergency days, or the final day of school—these vary by district and are not consistently observed statewide.
In fact, many Illinois school systems schedule the end of the academic year in late May, often just before or shortly after Memorial Day. Some districts list their final student attendance days around May 20–22, while others extend slightly beyond the holiday depending on emergency days used.
Following the Memorial Day holiday, most Illinois students either return briefly to complete the school year or have already concluded classes, as districts transition into the summer break period.
