Also known as Walpurgis Night and St. Valborg's Mass Eve, this holiday is celebrated on April 30. Valborg is celebrated in memory of Valborg/Walpurgis/Wealdburg/Valderburger who was made a saint on the 1st of May 779; however, the spring festivities are inherited from the Pagan festivities with huge bonfires. Valborg is today celebrated without parallels to the Christian church or religion.
