My first encounter with this information was due to a plasticized playing-card-sized two-sided perpetual calendar that Popular Science mag used to send out for subscription renewals. Later I found that George Washington and the other Founders often wrote both their birth dates. Finally, doing genealogy, one runs across this somewhat often.

Nations changed their adoption of the Gregorian at different times, spanning over two hundred years I think (the last major one being the USSR, Russia was still on the old calendar).

I always have fun when I lecture about our first and greatest President, George Washington. His birthday changed during his lifetime!

As a kid I read a mystery novel set in colonial America where this was one of the plot points. Now I am going to have to go see if I can find the book. :)

But apparently it did anger some people because it messed up their account books. Which I find very understand able.
