The whole concept of wishing things for the New Year and resolving yourself to live differently once the clock strikes 12 is rather mystical, if not religious.
A lot of people, of course, have given up on New Year’s resolutions.
For many Russians, it is a much much bigger deal that Christmas, for obvious reasons.
Initially, the Soviets tried to replace Christmas with a more appropriate komsomol (youth communist league) related holiday, but, shockingly, this did not take. And by 1928 they had banned Christmas entirely, and Dec. 25 was a normal working day.
Then, in 1935, Josef Stalin decided, between the great famine and the Great Terror, to return a celebratory tree to Soviet children. But Soviet leaders linked the tree not to religious Christmas celebrations, but to a secular new year, which, future-oriented as it was, matched up nicely with Soviet ideology.
…The blue, seven-pointed star that sat atop the imperial trees was replaced with a red, five-pointed star, like the one on Soviet insignia. It became a civic, celebratory holiday, one that was ritually emphasized by the ticking of the clock, champagne, the hymn of the Soviet Union, the exchange of gifts, and big parties. Source
For the New Years celebrations, most Russians will clean their house like their hosting judgment day. They will cook up so much food as if it’s their last meal on this earth. They will call their frenemies as if they are making peace before they die…
I still think that there is no such thing as a truly non-religious mindset. A religion will creep in, whether you call it a religion or not. And it’s not necessarily a bad thing, at all.
