In Russia, the New Year is often grander and even more widely celebrated than Christmas, which takes place on January 7. In fact, Russians celebrate two New Years: one on January 1 with the rest of the world and one on January 14, the so-called “old” New Year. The latter is based on the Orthodox Calendar.
Russians welcome a new year by saying, “S Novim Godom” (С Новым годом). Be prepared to say it often if you’re traveling around Russia between December 30 and January 15. Whether you’re in Moscow or Saint Petersburg, there will be a variety of activities to help you celebrate both Russian New Year’s Eves.
Most New Year celebrations in Russia occur from December 31 to January 1, like most other countries. You can count on there being lots of fireworks and concerts to mark the special holiday.
