19 year today and russ. The russefeiring (English: "russ celebration") is a traditional celebration for Norwegian high school students in their final spring semester. The russefeiring traditionally starts on around 28 April and ends on 17 May, the Norwegian Constitution day. On this date, russ are allowed to put on their overalls and officially become russ. There are several different types of russ differing in the colour of the caps and traditional uniforms most students carry during the entire russ period. The colors are red, blue, green and black for what one has studied at high school.
