That’s my current age in days.

It occurred to me today while running that I had missed the chance to celebrate my 10,000th, well, I would say “diaversary“. However, the term “diaversary” seems to refer to your “birthday” as a diabetic, though I’m not sure if this is the day of the diagnosis or what exactly it marks.

Anyways, I’ll probably celebrate the 12345th day of my life. Of course, this nice pattern of increasing digits is rather arbitrary, as it depends on the decimal system. If you write the same number in binary you get 11000000111001. So it’s not so much a property of the number itself as of its representation. In the meantime, I might also celebrate my 10809th day, as this is a lucky number. [Yes, there’s a mathematical definition for a number to be a “lucky number”.] The property of being a lucky number is, just as the property of being a prime number, independent of the representation. So this is as good an excuse as any to celebrate.

For the nerds: The Goldbach’s Conjecture also seems to hold for pairs of lucky numbers, which are always odd.
