There’s No Full Moon This Month—for the First Time in 19 Years

Instead, we're getting a "Black Moon."

You might recall that last month we got a Blood Moon/Blue Moon/Supermoon Eclipse, all at once. It was a special occasion, and it was actually so special that it affected this month by denying us a full moon. That’s right. For the first time since February 1999, we will have no full moon this month. And here’s why.

A key part of last month’s moon, aside from the eclipse, was that it was a Blue Moon. What this meant was that rather than getting one full moon in January, we got two. Basically, a Blue Moon = the second full moon in the same month. And that meant that we won’t get the next full moon until March 1, leaving February without one.

Now, just as a general side note, this definition of a Blue Moon is not technically correct. The more traditional definition states that a Blue Moon is either the third or fourth full moon in a season. But an article in Sky & Telescope from March 1946 gave a simpler, albeit incorrect definition, which stuck in the public’s mind. And that’s what we’ve been rolling with ever since.

It's also worth noting that neither full moons in January nor March were or will be actually blue. The term is a poetic description of its timing, not its colour. And this applies equally to February’s non-event full moon, which will be called a Black Moon, but won’t actually be black. It’ll be just almost full, but not quite, and then the date will imperceivably roll over and land the full moon in March. Snoooooze.
