That's technically not correct. Russia, at the time of the revolution was on the Julian calendar, which called for a leap year every 4 years. Earlier, in 1582, it was discovered that the Julian calendar would drift as time went on, so Pope Gregory directed the conversion to the Gregorian calendar and its new calendar rules. The Gregorian calendar rules are: there is a leap year every 4 years unless, that year is divisible by 100, then there is no leap year, which a further modification to that rule, that if that year was divisible by 400 then there was a leap year. This meant in the Gregorian calendar the year 1600 was a leap year, but the year 1700 was not. In the Gregorian calendar, there are 97 leap years for every 400 years. In the Julian calendar, there are 100.
In order to return the Gregorian calendar to a known starting point - Spring Equinox to be on March 21, days had to be removed from the calendar. Initially, the first countries to convert to the Gregorian calendar were the catholic countries (Italy, France, Spain, catholic Netherlands). The protestant countries resisted. Prussia converted in 1610, England (and thus the American colonies) in 1752.
Russia was late to the conversion. By the time Russia converted to the Gregorian calendar, additional days needed to be removed from the calendar (Italy only needed to remove 10 days in 1582, Russia needed to remove 13).
One of the last countries to convert was Greece in 1924 and Egypt in 1928.

So what you’re saying is what I said, only longer. Got it.
