Christmas on Campus is an annual event at the University of Dayton in which children are invited to campus to celebrate the Christmas holiday. It has become one of the nation's largest single-day, on-campus community service events. University students buddy up with area children and treat them to seasonal shows, displays and food. The event is held on December 8 each year, the same day as the Feast of the Immaculate Conception. It is one of the largest events hosted by the University of Dayton, and has a student organization devoted to preparing and running the event. It is considered by some to be an integral part of the campus' spirit.
