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…

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

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.

The American date notation is simply a direct reflection of the spoken language. We say "February second, 2020" and we write "2/2/2020". (Contra the root comment, I can't agree that 2/2/2020 is a palindrome.) I don't see this as being crazy or even unusual. When order matters, you invariably want big-endian notation, which is why that notation is acceptable everywhere regardless of the usual native notation. But by t…

Interesting. We (Australian) say "Second of Feb, 2020". ;)

What about the Fourth of July then?

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.

So the universe creates time?

What about it? It's the name of a holiday.

12/25 is often called Christmas, and yet 9/29 is never called Michaelmas. Same thing.

I don’t know, I always imagined that you said “4th of July” because up to that point you were Brits and that’s how we say it.

...and then the very next day, without adult supervision, you started saying your dates weirdly and dropping the “u”s out of words, stuff like that.*

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.

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