Prepare for some neo-Pagan crackpots to crowd out in Stonehenge.

Once in a Blue Moon

In case you have noticed, there was another full moon on the 31st. The second full moon of the month is also known as the blue moon.

This rare occurrence is probably the origin of the term "once in a blue moon," which alludes to something that occurs rarely.
