David Bowie is getting his own holiday in Chicago

Been looking for an excuse to don some Bowie-style red and blue face paint? Now’s your chance: Chicago has deemed Sept. 23, 2014 David Bowie Day.

A new exhibit that looks back at Bowie’s career (David Bowie Is) opens that same day at Chicago’s Museum of Contemporary Art. Chicago mayor Rahm Emanuel urged Chicagoans to visit the exhibit in a proclamation that made the holiday official. “David Bowie Is offers insight into the innovator, the rebel, and most importantly, the man,” reads the proclamation, signed Sept. 12 and obtained by Flavorwire.

The museum’s Bowie exhibit will house more than 400 objects relating to the musician’s 50-year career, ranging from handwritten diary entries to stage costumes. During those 50 years, Bowie has been inducted into the Rock and Roll Hall of Fame, honored with the Grammys’ Lifetime Achievement Award, and become a success in both his native U.K. and in the U.S.

Bowie’s next record, Nothing Has Changed, will feature his greatest hits from 1964 to today, as well as some previously unreleased tracks. The album comes out Nov. 18.
