So it happened like 900 yrs ago and after next one it almost take 900 yrs for same date to happen. And I am alive on one of this rare event. Need to cut Cake. :

  Not to sound corny but if you really think about it every single day is rare, just in different ways.

    Reminds me of the interesting number paradox[1]. This can be easily extended to dates too in this manner: Every date is interesting. Proof by contradiction: If there exists a non-empty set of uninteresting dates, there would be an earliest date in this set. But the earliest such date is itself interesting because it is the earliest uninteresting date, thus producing a contradiction.

      there has got to be a better objective method to define interesting numbers other than inclusion in a number sequence compendium. perhaps if we hypothesize that there are a (countably) infinite number of number theoretic theorems, might every number be either a unique case or the largest or the smallest example of some instance?
    • Retric 7y ago
      There is no largest or smallest real number. Therefore a set without a largest or smallest member is not necessarily empty. Alternatively, being the smallest in the set of uninteresting numbers does not make a number interesting, at best it is unique like every other number and therefore uninteresting.

        Not true of dates though, since you can set hard bounds at the big bang (or whatever) and the heat death of the universe.
        • _morgs_ 7y ago
          So the universe creates time?
          • dkersten 7y ago
            Yes. After the heat death, nothing will ever move or change and so it the universe will remain in a frozen state. Time will have stopped. Sine time is relative based on the observer and observed, if neither change in any way (no “work” happened and no information is exchanged, even on the level of fundamental particles (or fields/loops/strings or whatever happens to be at the bottom)), for every possible combination of observer and observer, then time has not advanced in any meaningful sense.

          You don't need both bounds anyway. A countable set without a lower bound in any representation is already a paradox.

        > There is no largest or smallest real number. The interesting number paradox applies to natural numbers, not real numbers. > Alternatively, being the smallest in the set of uninteresting numbers does not make a number interesting You are taking this too seriously. :-) Everyone would agree that "interesting" is subjective. This is supposed to be a humorous paradox, not a mathematical fact!
        • Retric 7y ago
          That was meant to be humorous, however dates are not natural numbers.

    Yes. I know. I Know. But you can't cut cake everyday. Need to make up some reason.
