I was so disappointed to learn that a blue moon is not actually blue.

Only your comment made me realise that. And I was already excited about new year with a nice little astro-gimmick.

The Straight Dope covered this awhile back:

The "two full moons in a month" definition is recent and somewhat bogus, like the bit about the seasons officially starting on the solstices and equinoxes. Originally "once in a blue moon" meant "pretty much never", and the modern definition stems from an error made writing a question/answer for Trivial Pursuit.

On New Year's Eve, no less! How...poetic. Now we've just to figure out what it all means.

It means our subdivision of a year into months of 28-31 days is quite arbitrary and purely historical.

Yeah. Also, for glasses, I think we should just wear 2009 glasses and take them off in celebration and toss them high in the air to ring in the new year, instead of wearing a "1" on our noses.

Except in Australia and Asia.
