My exact thought about an hour ago was: “It’s still the first of February?”  Must be time to head to bed.  I think I lost a day…!

So, yesterday was 12-12-12.  That brought up the question: 12 is a dozen; 144 is a gross; what is 1728 called?  That is 12 times 1, 12 times 12, and 12 times 12 times 12.
