Once every five years the university celebrates its lustrum. In that year, the university organises events that are open to the entire city. The lustrum traditionally starts during the Dies Natalis: the birthday of Utrecht University.

In 2021 Utrecht University celebrated its 77th lustrum together with UMC Utrecht. With the theme Creating Tomorrow Together students, staff, alumni and residents of the city of Utrecht were invited to think about the future together.
