Nuuttipukki (it is translated as the New Year Buck in some sources), is a horned, goat-like humanoid with an entourage of masked folk and he visits houses during the Saint Knut's Day. It used to be on January 7 but nowadays Saint Knut's Day is celebrated a week later. It is celebrated in Finland.
Nuuttipukki: Celebrated on 13 January in Finland, Sweden and Estonia as Saint Knut's Day (nuutinpäivä) is a tradition has been observed which is somewhat analogous to the modern Santa Claus, where young men dressed as goats would visit houses. Usually the dress was an inverted fur jacket, a leather or birch bark mask, and horns. Unlike Santa Claus, Nuuttipukki was a scary character compared to Krampus. The men dressed as Nuuttipukki wandered from house to house, came in, and typically demanded food from the household and especially leftover alcoholic beverages. Unless Nuuttipukki received a salary from the host, he committed evil deeds.
Nuuttipukki is a goat-like thing, also referred to as Krampus, which is the opposite of Santa Claus. It originated in Sweden and Finland and is part of Saint Knut's Day, which is celebrated on January 13th. Men would dress up like Nuuttipukki, with fur and horns and go to houses demanding food and drink. If Nuuttipukki didn't get want he wanted, he would do evil things.
It is the oldest version of Sanca Claus, that originated in Finland. The Nuttipukki (Christmas goat) was believed to be some sort of creature, wearing a mask and goat horns, that in Christmas eve went home by home demanding food and beverage.
In rural Finland, Knut's Day on January 13 was celebrated until after the war by parades in which a masked Knutsbock (Finnish nuuttipukki), often in a retinue, went from house to house. This figure was wrapped in animal skins, masked beyond recognition, and usually also horned. As a kind of early anti-Santa Claus with pre-Christian, pagan roots, the Knutsbock was above all terrifying; he did not distribute gifts, but cheekily helped himself to everything that was left over from the Christmas feast in the house - not least alcoholic beverages.
Finnish for Nutcracker- a figure like the yule goat- a man dressed as a goat and even creepier than Krampus. So ancient and widespread I'm doubtful the original country is really Finland. But, as I can't trace it back further reliably I have to say Finland.
