Once in a Blue Moon...
I read today that the Blue Moon syndrome happened Sunday November 21; hence once in a Blue Moon... is now.
Occasionally, there will come a year when there are 13 full moons during a year, not the usual 12. The almanac explanation continued:
And with that extra full moon, it also meant that one of the four seasons would contain four full moons instead of the usual three.
"There are seven Blue Moons in a Lunar Cycle of nineteen years," continued the almanac, ending on the comment that, "In olden times the almanac makers had much difficulty calculating the occurrence of the Blue Moon and this uncertainty gave rise to the expression 'Once in a Blue Moon.'"
