Every full moon phase has a different name, usually based around the month and the time of year that it is. December’s moon is called the Cold Moon for example, October is the Harvest Moon, etc. A Blue Moon, on the other hand, is a phenomenon, rather  than a way of marking the passage of time as it used to be.

Is the Blue Moon really blue?

No, while sometimes the moon can appear tinted like a reddish or orange shade, usually during an eclipse. Blue is actually not one of the colors the moon appears to be. The name “blue moon” doesn’t come from the shade, but from an Old English word for “Betrayer”. It betrayed the calendar, and was one of the moons that people believed inspired traitors to show their true colors under. The images of the moon that look as though they’re tinted blue are usually altered post picture taken, or often just the result of a very “cool” setting on the camera.

When does the blue moon come around?

The lunar calendar has about 12 full moons in the year, which seems almost perfect as a 12 month/year calendar. But the Solar year is 365 days, measuring the time it takes the Earth to travel around the sun. The lunar calendar measures twelve full moon cycles, three for each season. The result is that the lunar calendar falls short of the solar calendar by 10-11 days. And this 10-11 day discrepancy in the lunar calendar needs to be made up for somehow.

That’s where the “Blue Moon” appears, which is usually every 2.7 years (or 32-33 months).

When was the last Blue Moon?

Blue MoonThe last one appeared back on July 31st, 2015.

When is the next Blue Moon?

The next blue moon is due to show up in January. January 31st, 2018 to be precise.

2018 is actually a special month when it comes to the blue moons. Not only is there a blue moon at the very beginning of the month, there’s another one coming up in March. March 31st, 2018 is going to be considered a blue moon as well, because there will be two full moons that month. There are other reasons the blue moon comes around, but those reasons are harder to predict, and therefor harder to track across time.

After that, there won’t be another blue moon until October, 2020.
