According to the popular definition, a Blue Moon is the second Full Moon to occur in a single calendar month.
According to my friend Google, there will be 41 months that have two Full Moons in every century, so you could say that once in a Blue Moon actually means once every two-and-a-half years...
...which is not often, hence the popular saying "Once in a Blue moon."
You learn something every day!
