The origin of Once in a blue moon?

Once in a blue moon has come to mean once in a great while, but the actual frequency of blue moons averages about once every 2.7 years, a blue moon being the second full moon in the same month of a solar calendar. That average frequency is exactly the same as the average frequency of a leap month in a lunar calendar. The calculation of the average frequency of blue moons does not take into account that January and March of 2018 will EACH have two full moons, a rarity caused by the fact that February does not last as long as a lunar cycle.
