Tag of the Week: Blue Moon

Tag of the Week - Blue Moon

You might be familiar with the term, "once in a blue moon," an expression that's come to represent a rare occurrence.

Literally, once in a blue moon, describes the second full moon in a calendar month.

Seeing two full moons in a single month is fairly rare since the average time between full moons is almost 30 days, but on average it happens every three years or so. Maybe not as rare as you'd think.

In honor of this occurrence, I've created the Tag of the Week and named it "Once in a Blue Moon."
