Because month day year was how I was raised learning it? Of course it's going to make more sense to me that way. And the other way is going to make more sense to you.
Saying February 10th, 2011 just sounds right. It sounds more official. It sounds more correct. And having the month comes first just sounds better than the day.
I can't explain it, but it just does. And it's because that's how I learned it. And I'm always going to think that. Because to be completely honest, I'm one of those people that thinks the "american way" of doing things is the right way. But that's how I was raised.
