There are several types of calendars that are available to the Oak Park Community - a printed calendar, an online calendar and departmental calendars. Calendars list the City events, government holidays, promotional activities, and the meeting dates of the City Council and Boards and Commissions. The printed calendar is mailed to every household and every business in Oak Park by the first week in January. The online calendar can be accessed below. And, departmental calendars are found on each department's web page in the upper right corner of the page.
