Merry Christmas to All: Second Greatest Event

I wish you all a very Merry Christmas 2011.

I suggest you scroll down and turn off my music player.

Now if Christmas is the Second Greatest event, what must be the first?

No, not my birthday, although that's in the Top Ten somewhere.

I'll give a hint. We wouldn't have had the first, if we hadn't had the second, so the second came before the first.
