    Zero was invented after Roman Numerals and the Julian Calendar. That's why there was never a year Zero between BC and AD.

        @neiltyson The “AD” system of years was invented in 525, who also used the term “nulla” for 0. Well after the invention of the number 0.

        @neiltyson The more shocking thing to most people will probably be that zero was invented.

        @neiltyson do you watch the game? Or do you just think of a bunch of random, slightly relevant trivia? #superbowl #realtalk

        @Glass_Goddess @neiltyson The Mayans did have the concept independently, but European exposure to zero predates "New World" contact.

        @DianeLMajor That's interesting, I love ancient Art History, but I really need to go back to more reading and less tv.

        @neiltyson it would be odd to have a zero year!
