Maybe in English-speaking countries. Try reading Russian history books, and you will see old dates right up to 1918. That's why it's called "the October Revolution", although it happened on Nov 7th. To this day, Jan 14 is "the Old New Year day" for many people in Russia and other countries. The Russian Church is still using the Julian calendar, according to http://en.wikipedia.org/wiki/Old_New_Year. So much for "almost nobody". > It's true that it's also common practice to use the Julian calendar > when talking about events that occurred before 1752 in British-contolled > territory, and to use the Gregorian calendar for later events in that > territory.
