Yes, I know that I am posting this on Wednesday. Get off your high horse like you've never been late before. Sheesh!
I wont go into the origins of the name, you can look it up on Wikipedia. But, Tuesday is Thursday's twin sibling. It does not inspire people to write about or rejoice in its impending occurace as its not the beginning of the work week, nor is it the middle. Its in that nebulous space in between. Just as Thursday is between the middle and the end, that's why I consider them twins of a sort.
