Sign up as an event organizer of the Night of Science 2027
The Night of Science is a block party for science and research and is celebrated annually in Helsinki. The program is created by many different scientific and cultural organizations and actors. Join the organizers of the Night of Science 2027 by signing up for the mailing list.
The next Night of Science takes place on Thursday, 21 January 2027. Event organizers are free to plan any kind of events they wish. In previous years, the Night of Science has included lectures, workshops, theatre performances, guided tours, city games, and exhibitions. We are looking for both urban and online events for the Night of Science 2027. Combinations of these two are also possible.
To be part of the Night of Science, the event must meet five conditions. Event organizers must sign up by 13 August 2026 and submit the programme information by 20 August 2026. The event programme must be based on research, the event must be free of charge, and it must be held in accessible venues.

The event organizers are responsible for all matters related to their own events in the Night of Science (program, timetable, place, cost, etc.). The Federation of Finnish Learned Societies (TSV), which coordinates the Night of Science, is responsible for compiling and publishing the program, as well as for the communication and marketing of the event.
TSV encourages event organizers to cooperate with each other. The event organizers’ meeting in May will provide an opportunity to discuss ideas and tentative plans for upcoming Night of Science. The invitation to the event will be sent to those who have signed up for the event organizers' mailing list in April.
