nikoluksen
Nikoluksen is a term that can refer to several things, primarily associated with Saint Nicholas. In some Orthodox Christian traditions, particularly in Finland and Russia, "Nikoluksen" can be a colloquial or informal way of referring to Saint Nicholas himself, or a celebration or feast day dedicated to him. For example, Saint Nicholas Day is observed on December 6th in Finland and on December 19th according to the Julian calendar, which is January 6th in the Gregorian calendar in some Orthodox churches. The name "Nikoluksen" is the genitive case of "Nikolaus" or "Nikolai," indicating possession or association with the saint.
In a broader sense, "Nikoluksen" might also be used informally to describe things associated with Saint Nicholas,
