How did the number "13" end up being unlucky?
How did the number "13" end up being unlucky?

It comes from the idea that in the past, people counted on their fingers. They didn’t actually have the number 13, so instead they used the number 12. Now people don’t use fingers for counting, but the older way of counting remains in our language and other systems (e.g. dating systems).

I can't understand how that makes sense. Don't we have 10 fingers?
user
Good point! There are actually 12 different kinds of hand bones, and the thumb counts as one.
