Eclipse Countdown: 4 Days Left

With the Eclipse movie coming out did you ever wonder what some of the titles of the Twilight saga actually mean. Like what exactly is an eclipse and when is twilight?
Being the big dork that I am, I look up all the titles and found out the meaning of them on Wikipedia.

Here they are:

Twilight: Go here

New Moon: Go here

Eclipse: Go here

Breaking Dawn: Go here


Do you think the actual meaning of these events goes with the books that have their titles?
Let me know what you think!
