Dillo Day

Dillo Day is an annual all-day music festival at Northwestern University that takes place at the end of spring quarter on the Lakefill.

Started in the 1972/73 school year, it is organized by Mayfest Productions, a Northwestern student group, and is the largest student-run music festival in the country.

That same year, a 10-day assortment of campus programming called Mayfest began, which included Armadillo Day, Greek Week and A&O's Spring Festival.

This once again featured virtual artist performances and live Q&A's, but also had in-person components across campus the entire week of the festival similar to the original Mayfest.

This included Mayfeast, a collection of food trucks outside Deering Library; Mayfit, a thrift shopping event at Norris University Center; Dildo Day, a variety of sex/body positivity events; student art installations on the Lakefill where the festival is traditionally held; a silent disco outside Norris featuring Chicago area DJ's; and screenings of artist performances on and off-campus.
