I love the term "middle endianness" and how clearly it highlights how nuts the American date notation is. EDIT: fwiw, in my native language, most numbers from 100 and 1000 are pronounced middle endian, so I'm not complaining.

Just as with inches, feet, and pounds the system works better in practical real world conversation than it does in more formal language. “When’s your birthday? 10/23. When are we going to Ma’s? 11/19 thru 11/29. When do you go back into therapy? 12/8.”

It doesn't "work better" than any other system, you're just more used to it.

The nice thing about today's date, 2020-02-02, is that it is palindrome in three date formats: YYYYMMDD, DDMMYYYY, and MMDDYYYY. This should probably be called "Universal Palindrome Day" because it is a palindrome irrespective of the endianness (big, little, or middle) that is used in various countries. Here is the list of all such dates until the year 9999: 0101-10-10 1010-01-01 1111-11-11 2020-02-02 2121-12-12 3030…

Does you native language also have gendered numbers? Is there gender parity with odd numbers male and even numbers female? Or does it enforce the numeric patriarchy by gendering prime numbers male and composite numbers female?

For those in the US, also groundhog day and superbowl sunday (american football championship).

> superbowl sunday (american football championship). And for many it's "watch a bunch of ads with budgets in the $5-10+ million range" day.

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.

> I hope this is pointed out to kids in classrooms all over the world. 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.

Where I live the year isn't 2020. So, meh.

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.

Their name will be otto

Any responsible parent will call him Bob or Anna, of course. Taking surnames into account is going to be a bit harder. Here's a good resource for anyone becoming a parent today: https://parentinghealthybabies.com/palindrome-names/

Oof, that list is terrible. Natan is listed twice, and there’s at least one name that isn’t a palindrome. The only two names that really work from that list is Anna and Hannah. Nobody should name their kid Bob in 2020, it’s not a «young» name yet. Thr older Bobs need to die off before it’s an acceptable kid’s name. As for the rest of those names, I refuse to acknowledge them as names. They’re more like onomatopoeia.

One of the names in that list should be Aziza, instead of Azia. It means dear or precious in Arabic.

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.

> 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!

That was meant to be humorous, however dates are not natural numbers.

Amazingly, my last comment swapping "his" with "their" was flagged to death.

If we're ever going to be more embracing of people other than men, it's gotta start with us. We can't just mis-gender and then pat ourselves on the back thinking we're doing something to fix the inequalities in our fields, and the fact that it sticks out like a sore thumb on hackernews is heartbreaking. :(

Also they contain only two distinct digits, rest mostly have 3 or more different digits.

Yeah, we won’t get a two-digit universal palindrome for a long time (12-12-2121).
