1900 is MCM in Roman numerals.  It is the largest palindrome in Roman numerals.


  1. Once again, Amy's blog has sent me off to some interesting research. In this case, the question "where are some places where Roman numerals are still being used today? hit me. Though I pretty well always stay to the end of the credits of every movie I go to see, I couldn't remember if the dates were still in Roman numerals or not. So I googled it and came up with some cool stuff on Wikipedia. The most interesting to me was that the idea that the Romans didn't have a zero is not quite correct. They used the term "nulla", the first known use being in 525, with just the letter "N" being used in around 725. I started posting this comment about twenty minutes ago, and just back from an interesting trip through zero's history. Oh well...always allow plenty of time to run amok when reading number-of-the-day. :)

  2. 2000 is MM. That's a larger palindrome.
    And, of course, there's MMM, which is 3000.

    1. You are right. I guess I shouldn't just copy something without thinking about it first.
