Bun Day, or Bolludagur, is observed in Iceland every year on Shrove Monday, which falls on February 16 in 2026. This celebration is part of the Pre-Lenten season, where Icelanders indulge in cream-filled buns, reflecting a tradition brought from Denmark or Norway in the 19th century. The buns, often made from choux pastry, are typically filled with whipped cream or jam and covered with chocolate or caramel glaze. Historically, children would decorate sticks and lightly spank adults while chanting "Bolla, bolla, bolla!" in exchange for buns. Although this playful tradition has waned, the consumption of these festive buns remains popular, with Icelanders estimated to eat over a million buns each year, averaging three per person.
