It's still a headache when dealing with even relatively recent Russian
history, *not* helped by the Soviets' tendency to quote pre-changeover
dates using the new calendar, as if the change had happened earlier.
For example, you will often find two different dates for the birth of
historical figures like Tsiolkovskii, depending on choice of calendar.
