Currently, the old pre-revolutionary calendar lags behind the modern one, so the beginning of the new year is celebrated according to it.

Yes, when Russia was still dominated by the calendar of Julius Caesar – the Julian calendar. Julius Caesar did not think that he would be mistaken when compiling it, but … The unofficial New Year is not struck by the chimes of the city of Moscow. This time is the night of January 13-14. The difference between the two “brothers” -calendars increases by one in the century when there is no possibility to divide the year of the century by the number four. The 20-21st centuries carry a difference of 13 days, hence the celebration of our “New Year Old Man”. In the 22nd century, this will be a difference of 14 days.
