In Russia, we have a lot of holidays. Some think we have way too many holidays, but I’m kinda used to it, so I’m not fit to judge.
Most of Russia doesn’t observe Christmas on December, 25 (the prevalent church here is the Russian Orthodox who never switched to Gregorian calendar, so Christmas is January, 7). However, the USSR legacy (they tried to make the church-related holidays obsolete by introducing the non-church-related holidays about vaguely the same dates) of celebrating The New Year on January, 1, combined with the modern Russian return-to-roots state-wide celebration of Christmas, results in the state-sanctioned holiday (think of it as “bank holiday” in Western terms) spanning most of the first half of January.
