Come celebrate the University in 2015! The opening ceremonies of the anniversary year take place in January, when some of the works of the Lux Helsinki light art festival can be seen on the City Centre Campus. The official anniversary celebration is on 26 March, and will involve events for the public in addition to an invitation-only function at the University. At the beginning of September, the University is inviting everyone to enjoy Thinkfest, the urban festival of thought and science. The anniversary year culminates in the award gala and closing seminar for the Helsinki Challenge competition in November. The year also features events suggested by members of the University community. These are marked on the University calendar with a 375th anniversary logo.
