you saw me standing alone

We get a blue moon tonight. As a luna-tic, I love blue moons. But as SOKOMC, let me remind everyone that blue moons are not all that rare. To happen "once in a blue moon" means "not all that often." But not "rarely." We get a blue moon about twice as often as Leap Day. It's a function of having a slightly imperfect lunar calendar (months are actually "moonths").

Enjoy it, and celebrate by doing something you seldom do!

And here's my favorite smart guy, Neil DeGrasse Tyson, on the subject:

A blue moon is just a second full moon. The average time the moon takes to complete a cycle of phases is 29.5 days. Every month except February can have a second full moon. Chances of a full moon on the first of the month, like we had this month, is about 1 in 30. So blue moons happens about once every 30 months. About 2 1/2 to 3 years. Not really that rare, my friend.
