For a few magical evenings each year, the sun decides to put on a show in Manhattan. It lines up perfectly with the city's grid, bathing the canyons of concrete and glass in a spectacular, almost otherworldly golden glow. We call it Manhattanhenge, and it's basically New York's version of a celestial red carpet.
But here's the thing: you don't need to be dodging yellow cabs to experience this cosmic alignment. Apparently, the sun is an equal-opportunity show-off. And now, there's an app for that.
Enter Hengefinder, the brainchild of data scientist Victoria Ritvo and software engineer John Pribyl. Because why should New Yorkers have all the fun, right? This ingenious little tool lets you plug in an address or city, and poof, it calculates when the sun will perfectly align with your local streets or even a particularly well-angled canal. No complicated math required, just your curiosity and maybe a camera.

Start Your News DetoxRitvo, a self-proclaimed henge enthusiast, is particularly charmed by the idea of the Haarlemmertrekvaart, a canal in Amsterdam. She suspects that for the past 400 years, this very canal has been hosting its own twice-yearly henge, reflecting the setting sun off its historic waters. Which, if you think about it, is both impressive and slightly terrifying that it took us this long to notice.
Not Just a Pretty Sunset
The science behind it is surprisingly simple: the sun's setting position shifts throughout the year. If a street (or canal) happens to be angled just so, on a couple of specific days, the sun will line up perfectly with its path. It's like the universe is just giving a little wink to our urban planning.
Astrophysicist Neil deGrasse Tyson coined the term "Manhattanhenge" back in '97, drawing a parallel to the ancient, deliberate alignments at Stonehenge. The key difference? The folks who built Stonehenge meant for that to happen. Manhattan's grid, on the other hand, was purely accidental genius. Because apparently, even cosmic beauty can be a happy accident.
So, while New York gets its moment in late May and mid-July, other cities have their own celestial rendezvous. Chicagohenge and Baltimorehenge typically grace us around the spring and fall equinoxes. Torontohenge makes its appearance in February and October. Your local henge might be happening right now, just waiting for you to find it. Go forth and witness your own perfectly aligned golden hour.
