Once in a Blue Moon

 



Have you ever wondered about the phrase "Once in a Blue Moon?" 
Something about it always seemed a little magical to me. Something rare and random. 

The phrase "once in a blue moon" originally meant "never" or "impossible," but it evolved over centuries to mean "rarely" due to changes in how we define a "blue moon."

In the 16th century, the phrase didn't mean "rare"—it meant "impossible". The earliest recorded use was in a 1528 anti-clerical pamphlet by William Roy and Jeremy Barlowe, which joked that if church leaders said the moon was blue, people had to believe it. It was basically the 1500s version of saying "when pigs fly".

The meaning shifted from "impossible" to "rare" by the mid-1800s. This was reinforced by the 1837 Maine Farmers' Almanac, which used "blue moon" to describe the rare third full moon in a season that has four.



The modern definition—the second full moon in a calendar month—actually came from a mistake!  For centuries, the Maine Farmers' Almanac defined a Blue Moon as the third of four full moons in a single season.

In 1946, writer James Hugh Pruett misinterpreted the Almanac in an article for Sky & Telescope, calling the second moon in a month a "Blue Moon". This "mistaken" definition is now what most of us use today.

The shift from "impossible" to "highly unlikely" was helped along by nature. After the massive Krakatoa volcanic eruption in 1883, ash in the atmosphere actually made the moon appear blue or green for nearly two years. Suddenly, a blue moon wasn't just a figure of speech; it was a rare, real-world sight.

Today, a "Blue Moon" (by the calendar definition) happens roughly once every 2.7 years. So the next time you use the phrase, you’re not just talking about a rare event—you’re participating in a 500-year-old linguistic evolution!

When I had the opportunity to purchase a beautiful book cover with a placeholder title of Blue Moon Cowboy, it felt meant to be! I loved the title and the cover.

Coming June 4 - Blue Moon Cowboy




He’s spent decades guarding his heart.
She’s spent a lifetime chasing the horizon.
Neither of them were prepared for love to catch them by surprise.

Widower Jason Price isn’t looking for romance. As a trusted pickup man for the Rockin’ K Rodeo Company, part-owner of his family’s ranch, and a proud grandpa, his days—and his heart—are already full. Love is for younger folks with fewer scars and more time.

Photographer Lainey Collins traded corporate life for the open road, capturing the faces and stories of everyday people. Living out of her travel van, she’s built a life of freedom, purpose, and just enough distance to keep her heart safe.

But when a chance meeting at a rodeo puts her in Jason’s orbit, everything begins to shift.

As Lainey sets out to create a book featuring the faces of the rodeo, she finds herself returning again and again—to the arena… and to Jason. What begins as a project turns into something deeper as sparks fly, laughter comes easy, and two guarded hearts start to open.

Falling in love is one thing.

But trusting it—and daring to build a future—is another.

Can a cowboy who’s learned to live without love and a woman who’s always kept moving finally find a place to belong… together?
