Today is Wednesday, the fourth day of the week (except for folks who don't count Sunday and then, today is the third day). It is the name of the little girl Addams. Wednesday is also a song by Tori Amos, the name of a couple of different films, a 70s pop band from Canada, and an opera. The poem says that Wednesday's child is full of woe.
It is often called "hump day" because it falls in the middle of the standard Monday through Friday work week and so once you finish Wednesday, you are "over the hump."
The are many significant things that can be said about this day, but I happen to think that all seven days of the week have special significance. We can do great things every single day of our life - it really doesn't matter what day it is! Since Wednesday though is the day upon us, let's go out and make it a wonderful one!
