Can hardly think of a Xmas meal. Nothing like turkey in Western Europe.
Usually winter holidays seem like 1 huge holiday starting few days before NY and ending some time after "Old NY" (NY Old Style=Jan, 14th).
Religious holidays were forbidden during Soviet times so I guess it might've influenced our traditions.
NY is one of the biggest holidays in ex-Soviet countries, Xmas is mainly perceived as another excuse for having NY hangover cure (another portion of alcohol), yummy meals, meeting friends and stuff
