Blue Moon 31st December 2009

Blue moon means the second full moon in a month.

This do not always happens, so it is something special.

This blue moon is something very very special because it happens on the last day of a year.

The last blue moon on the 31st December happened in 1990.

It happened 19 years ago.

At that time I was not born yet.

Anyway the moon is not blue in colour on the night of blue moon 🙂
