Answer 3

The phrase "once in a blue moon" means that it happens very rarely.

It is taken from the naming of a second full moon within a calendar month, which occurs rarely.

May 30, 2007: At 9:04 pm Eastern Daylight Time on May 31st, the full moon over North America will turn blue.

Not really. But it will be the second full moon of May and, according to folklore, that makes it a Blue Moon.

July 7, 2004: When you hear someone say "Once in a Blue Moon…" you know what they mean: Rare. Seldom. Maybe even absurd. After all, when was the last time you saw the moon turn blue?  On July 31st, you should look, because there's going to be a Blue Moon.

According to modern folklore, a Blue Moon is the second full moon in a calendar month. Usually months have only one full moon, but occasionally a second one sneaks in. Full moons are separated by 29 days, while most months are 30 or 31 days long; so it is possible to fit two full moons in a single month. This happens every two and a half years, on average.

The average interval between Full Moons is about 29.5 days, whilst the length of an average month is roughly 30.5 days. This makes it very unlikely that any given month will contain two Full Moons, though it does sometimes happen.

On average, 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.

very rare. A blue moon is when there are two full moons in a month. The blue moon is the second moon. It rarely ever happens.

Answer 8

Very very rare, like a blue moon, something that doesn't happen very often.

Answer 9

Due to an error in 1946, a Blue Moon is the second full moon in a calendar month.

It is possible to have a month with no full Moon, but only in February.
