Norwegian New Year's Eve Traditions

From http://library.thinkquest.org/18802/norxmas.htm#31

At 5 o'clock the children go outside dressed in wacky costumes. They go from door to door singing carols and are rewarded with candy, cookies or oranges. In a way, it resembles a mixture of trick & treating and caroling. In some parts of Norway, the children don't do this on New Year's Eve but in the afternoons between the 27th and the 30th. The tradition is called to go "Nyttårsbukk".

The fireworks start some hours before midnight, around 9pm and from it just builds up. Generally everyone can set off fireworks, but in certain areas where the houses are very close or made of wood, fireworks are restricted or illegal (for obvious reasons). December is the month when most fires occur in Norway, due to fireworks and a large number of knocked-over candles.
