We are divided into 2 groups: the Catholics, Protestants, Anglicans and modern Orthodox - on one side, and the traditionalist Orthodox - on the other. The latter (the Russians, Serbs, Ukrainians) do not acknowledge the new calendar, therefore they continue to celebrate Christmas two weeks later (January the 7th).
