Every year on 30 April and 1 May student organizations in Tartu celebrate volbriöö, which is connected to Walpurgis Night. It is one of the more awaited events of the year, an important tradition of the academic culture. This celebration unites different generations of alumni and students when the representatives of student corporations and student societies from Estonia and abroad gather in Tartu.
The celebration starts with the procession that brings together academic student organizations. The Mayor of Tartu and the Rector of the University of Tartu greet the procession that the townspeople gather to watch. Following the public procession each student organization holds its own events that are not open to public: performances, concerts, report nights, carnivals, students' joining rites, joint singing and beer tables. At midnight the corporations and societies open their doors and members of student organizations visit each other. Some of the student organizations also welcome smartly dressed townspeople. The volbriöö celebration can end with a pancake and soup morning, a boat ride, joint singing under the dormitory windows, a midday garden party or visits to elderly alumni.
