I hope this is pointed out to kids in classrooms all over the world. Growing up I remember my teachers would point out these cute number tricks/events which contributed to piquing my interest in math and numbers, and eventually engineering.

For at least some of them it’s the summer holidays and they are heat addled and doing something completely mindless with no idea of the day or date. I’m rather jealous.

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. [1]: https://en.wikipedia.org/wiki…

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?

The Human Palindrome will be born tomorrow and die on 2121-12-12 at the age of 101. And in true palindromic fashion, his life will start and end with diapers.

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.
