I like this one. People say \’once in a blue moon, and usually mean \’almost never\’, but at least this way, you can see when they happen!
\nThe average interval between Full Moons is about 29.5 days, whilst the\nlength of an average month is roughly 30.5 days. This makes it very unlikely\nthat any given month will contain two Full Moons, though it does sometimes\nhappen.\n |
\nAccording to the popular definition, it is the second Full\nMoon to occur in a single calendar month.\n |
\nOn average, there will be 41 months that have two Full Moons in every century,\nso you could say that once in a Blue Moon actually means once\nevery two-and-a-half years.\n |
Blue Moon Calculator\nIs there a Blue Moon this year? Next year? The year I was born?\n\nThe Blue Moon Calculator knows the answer!\n |
