Q. Why do mathematicians confuse Halloween and Christmas?

A. Because 31 Oct = 25 Dec.

Happy Christmas.

@kityates not being a mathematician I don't understand it.

@CuriousCat @kityates nor me! I thought it was maybe 31 octagons = 25 decagons, but not quite! 🤔

@CuriousCat @kityates
Well as I had to google for it, here you go :

short :
"Because Oct 31 represents the octal (base 8) number 31, which, when converted to decimal, is 25. Dec 25 is short for Decimal 25, thus the two are equal."

@johannbourquenez @kityates thank you. At first I thought I was being dense, but remembered that if I don't understand, there are always others like me.

@kityates My birthday is 31 Oct. Does that mean I have two birthdays each year or two Christmases?

OK smarty pants can you guys let us non-mathematicians in on this (obviously so I can share it as my own at Christmas dinner)

@kityates That’s an oldie. And it used to be computer scientists, when oct numbers were still a thingie.

@kityates Base 8 vs base 10. Says logical inference only. I do not do math if I can avoid it and I usually can.

@kityates You could have used the content warnings to point out that this is a non-binary joke...

31 Oct = 25 Dec
31 Octal = 25 Decimal
C: 031 == 25
Excel: OCT2DEC(31) = 25

@kityates - will I get blocked by #mastodon if I do the 'There are 10 types of people in the world, those who understand binary and those that don't'?

I'll get my coat...
