Which New Year's Eve countdown tradition in Denmark involves jumping from a chair at midnight?

Denmark's New Year's Eve tradition of jumping from a chair at midnight is called jumping into the New Year.

At midnight, some Danes stand on a chair, sofa, or other raised place and jump down as the clock changes to the new year. The action is understood as a symbolic leap from the old year into the new one.

The custom is one part of a broader Danish New Year's Eve, which can also include champagne, fireworks, and the televised New Year's address from the monarch. Another well-known Danish custom is throwing or leaving broken dishes at friends' and neighbors' doors, although practices differ among households.

The chair jump is symbolic rather than an official ceremony with a fixed national format. It should also not be confused with New Year's swimming or other midnight outdoor traditions found elsewhere.
