Once In a Blue Moon
January 1st, 2010. Filed under: This & That.
Once in a blue moon. That old saying means something doesn’t happen very often. That’s the way it is with blue moons.
A blue moon doesn’t actually look blue. It’s the second full moon in the same month, and we rang in the new year with one.
Something even rarer is a double blue moon. The last time we had two blue moons in the same year was in January and March of 1999. This happens only once every 19 years, so don’t expect to see it any time soon.
If you missed the blue moon last night, you can catch the next one in 2011.
