Kind of winter solstice-y. In Scotland the New Year's was the main celebration, they call it Hogmanay. It's just a local Scottish traditions, not Scythian or anything lol.

Traditions associated with it likely have influences from Scandinavians too, e.g. blond people (i.e Norwegian and Danish vikings coming to fuck your day up) are not allowed to enter the house first, because that's bad luck.
