Once in a blue moon, we witnessed one on New Year's Day and the day after. While having dinner January 1, 2010, we were astonished by the the sight of the great moon. I had struggles on taking pictures and wished that I have a telephoto- zoom lens.
A "blue moon" is also used colloquially to mean "a rare event", especially in the phrase "once in a blue moon".
Two full moons in one month:
* 2009: December 2; December 31 (combined with a partial lunar eclipse visible in some parts of the world)
* 2012: August 2, August 31
* 2015: July 2, July 31
The next time New Year's Eve will fall on a Blue Moon (as occurred on 31 December, 2009) is after one Metonic cycle, in 2028: at that time there will be a total lunar eclipse.-source-
2009 bridged us a magnificent entry for 2010. We're very grateful for these welcoming experiences.
According to popular definition, a blue moon is the second full moon in a month. But don't expect it to be blue – the name has nothing to do with the color.
