Estonia
In Estonia, Volbriöö is celebrated throughout the night of 30 April and into the early hours of 1 May, where 1 May is a public holiday called "Spring Day" (Kevadpüha). Volbriöö is an important and widespread celebration of the arrival of spring in the country. Influenced by German culture, the night originally stood for the gathering and meeting of witches. Modern people still dress up as witches to wander the streets in a carnival-like mood.
The Volbriöö celebrations are especially vigorous in Tartu, the university town in southern Estonia. For Estonian students in student corporations (fraternities and sororities), the night starts with a traditional procession through the streets of Tartu, followed by visiting each other's corporation houses throughout the night.
