40 years ago I read a book, but couldn't remember the title. I've been looking for it for a while, and I finally (finally!) found it!
And then I worked out why it took so long. It hasn't been released yet! In fact, according to this website I found it on, it won't be released for another seven millenia - when the Earth's spin will be so fast that December will have (at least) 80 days. Global warming? Pah!

may fixhave fixed it.)
Now obviously no human entered this wild date. It's a mis-decode of something - perhaps the ISBN? My question is: can anyone think of an existing decoding algorithm that was so messed up it would invent an entirely new calendar?
