July 4, 1776: Greatest Day Ever?

I wanted to pose this as a question to all my viewing audience, whoever that may be. Do you think that July 4, 1776 is the greatest day ever? How about the greatest day ever in the history of "freedom"?

Personally, the greatest day ever to me is the birth of Christ, as it not only brought our Savior into the world, but also was the birth of Western Civilization as we know it. However, historically, we do not know the ACTUAL day Jesus arrived into the world, even though we can guess which year within a solid decade.

Let's not lose the focus here. How important is the date: July 4, 1776? Where would YOU rank it in history?
