The Dutch New Year's Eve celebration is called Oud en Nieuw, meaning “Old and New.”
Oud en Nieuw describes the transition from the old year to the new one in the Netherlands. Celebrations commonly include gatherings, fireworks, champagne or other drinks, and oliebollen, deep-fried dough balls often containing raisins or currants. Oliebollen are strongly associated with the Dutch winter holiday season.
At midnight, people may exchange good wishes and gather outside to watch fireworks. The Netherlands has also debated fireworks regulations because of safety, noise, pollution, and animal-welfare concerns; rules can vary by year and municipality.
Oud en Nieuw is not a national holiday name like Koningsdag, which celebrates the monarch's birthday. Sinterklaasavond belongs to the December Saint Nicholas tradition, while Prinsjesdag is the annual state opening of parliament. These distinctions help identify the Dutch New Year term precisely.
