Your Zodiac Sign Is 2,000 Years Out of Date

Whether you care about horoscopes or not, you probably know your zodiac sign. You’ve probably known it for most of your life.

Zodiac signs were originally based on the stars. But over thousands of years, our view of the stars has shifted. That means, if you account for this shift, your sign might not be what you think.

Below, we’ll tell you what it would be instead.

There are three reasons the zodiac signs no longer line up with the constellations they’re named after.

1. Earth’s wobble

The Earth wobbles like a top. A spinning top starts to wobble soon after it is set into motion. The Earth does the same thing, only more slowly.

It takes 26,000 years for the North pole to trace out a complete circle in the sky, pointing at different stars along the way. Scientists call this wobbling motion axial precession.

This wobble means that our view of the stars shifts by one degree every 72 years. Over centuries, this difference builds up.

And it’s not just the Northern stars that shift in our view because of Earth’s wobble, but all stars — including the zodiac constellations.

Take the spring equinox, usually around March 20, the first day of spring in the Northern hemisphere (and the start of the zodiac calendar in Western astrology).

This shift in our view of the stars was discovered by Hipparchus over 2,000 years ago. Since you can’t see stars during the day, he waited for a lunar eclipse — when the moon is directly opposite the sun — and used the moon’s position to work out where the sun was.

By comparing his measurement with earlier ones, he found that our view of the stars shifts by about one degree per century — not too far from modern measurements.

Today, Western astrology uses the tropical zodiac system, which is based on the positions of the stars more or less as they would have appeared to Hipparchus, and not as they appear today.

That means that the zodiac signs familiar to Americans are in sync not with the stars, but with the seasons: Aries starts on the first day of spring, even though the sun is now in front of Pisces then.

In contrast, the Indian system of astrology uses the sidereal zodiac, which accounts for Earth’s wobble and aligns zodiac signs to the stars.

While these two systems were initially aligned, they have been drifting apart ever since. Western astrologers are well aware of this mismatch, but they don’t see a problem with basing the signs on the stars as they were two millennia ago.

“Astrologers using the tropical zodiac are just using what they consider to be an equally valid system,” said Dorian Greenbaum, a historian of astrology who teaches at the University of Wales Trinity Saint David.

2. Constellations differ in size

The zodiac signs were created around 2,500 years ago by the Babylonians.

Their star catalogs listed at least 17 zodiac constellations. But they eventually simplified these into the 12 zodiac constellations we know today, each 30 degrees wide, as if slicing the sky into 12 equal slices.

But constellations aren’t really the same size. In 1928, astronomers divided the sky into 88 officially recognized constellations, each one shaped like its own puzzle piece.

Official constellations along the sun’s annual path

“They are not nice equal pieces,” said Stacy Palen, emeritus professor at Weber State University. “They’re like jagged shapes that are not symmetric in any way.”

Advertisement

Based on these boundaries, the sun spends more than twice as much time in front of Virgo as in front of Cancer. And it spends only a week in front of Scorpio — if you include Ophiuchus, that is.

Which brings us to the last reason the 12 signs don’t align with the zodiac constellations.

3. Ophiuchus

Ophiuchus is the 13th constellation along the sun’s path, according to astronomers. (It even has its own emoji: ⛎.) Ophiuchus means “serpent bearer” in Ancient Greek, and is usually depicted as a man holding a snake. If you squint, you can kind of see why.

So for people born during the sign of Scorpio 2,000 years ago, Ophiuchus was more likely behind the sun on their birthday. (And because of Earth’s wobble, most Sagittarians today were also born when Ophiuchus was behind the sun.)

We don’t really know why the Babylonians left out Ophiuchus from their zodiac signs. They may have originally had a different name for it. But historians believe that when Babylonians simplified their zodiac system, they wanted the 12 zodiac signs to match the 12 months of their calendar. Ophiuchus didn’t make the cut.

A ‘shape-shifter’

Astronomy and astrology have little in common today, and there’s no scientific basis to the idea that the movements of the stars and planets influence our future or our personalities. But the two disciplines started out as the same thing thousands of years ago.

“If you were an astronomer, you were also an astrologer,” Professor Greenbaum said.

The Babylonians viewed the planets as gods, and planetary motions as omens that could foretell the fortunes of kings and kingdoms. This motivated them to look for patterns in the sky.

Even by the 17th century, many astronomers were also practising astrologers. Johannes Kepler, who discovered how planets move in ellipses, probably learned astrology at college, and created horoscopes for friends and patrons. Galileo practiced astrology and sold horoscopes on the side.

“Their side hustle was to cast horoscopes for their rich patrons because that paid the bills,” said Tyler Nordgren, an astronomer and author.

Eventually, during the Enlightenment, astrology was divorced from astronomy and was no longer considered a legitimate science, Professor Greenbaum said.

“It was kicked out of the universities,” he said. “But there were still practitioners.”

Today, we understand the laws governing the motions of planets and stars well enough to send spacecraft to distant worlds, detect gravitational waves and take pictures of a black hole. At the same time, over a quarter of Americans believe that the positions of the stars and planets can affect their lives.

So why has belief in astrology endured, while other methods of divination like ornithomancy (finding omens in the behavior of birds) or tyromancy (fortune telling with a block of cheese) have drifted into obscurity?

“Astrology is a shape-shifter,” Professor Greenbaum said. “Astrology goes along with whatever’s in vogue and manages to survive.”

Because those constellations are behind the sun, they’re in the daytime sky, and so you can’t actually see them on those dates. You’ll need to wait until they’re in the night sky, about six months from the date you entered.

How we found your sign

Advertisement

Though the astrological zodiac calendar is well known, there are small ways ours may differ from other sources. To calculate your astrological zodiac sign, we divided the sun’s annual path across the sky (known as the ecliptic) into 12 equal divisions of 30 degrees, beginning with the March equinox, which marks the beginning of Aries. This is the tropical zodiac system, in which zodiac signs are aligned to the seasons.

To calculate the astronomical zodiac constellation behind the sun, we used the Astronomy Engine software library to locate the sun on every day of the year and determine the astronomical constellation behind it.

We based our zodiac calculations on the current year, and on the position of the sun at noon UTC every day. A more accurate calculation of your sign would involve knowing the exact time and year of your birth, and as a result our calculations may be off by a day or so. This primarily affects people whose birthdays are on the cusp between two signs, or between two constellations.

Advertisement

To create the 3D illustrations of the stars, we used a repository of celestial data for the 88 official constellations, and oriented these constellations based on Earth’s view of the stars on a given date.

The astronomical calculations account for precession (the slow wobble in Earth’s axis of rotation), nutation (a slight wiggle in the tilt of Earth’s axis), and the gradual drift of Earth’s elliptical orbit.

Advertisement

Our star maps do not account for the movement of individual stars through space, relative to each other, known as proper motion. This movement is typically so slow as to be minimal over centuries, but the positions of some of the stars in the Northern sky during the last ice age may be in slightly different locations than shown.

In our visualizations, we used the familiar names Scorpio and Capricorn instead of the official names for those constellations: Scorpius and Capricornus. The seasons we describe are for the Northern hemisphere. The Earth’s orbit around the sun is actually counterclockwise when viewed from above; we show it orbiting clockwise for illustrative purposes. The Earth and the sun are not to scale.

For decades, Deborah Willis has dedicated her career to unearthing, cataloging and showcasing Black photographers and photographs of Black people. The MacArthur “Genius Award” winner is the author of a spectacular collection of books including the seminal Reflections in Black: A History of Black Photographers, 1840 to the Present.

Twenty-five years after its publication, a new edition of Reflections in Black is out with 130 new images and a gallery show inspired by the book. In the expansion of this book, Willis considered the effects of migration and the importance of images for people forced to leave home.

“The aspect of migration is a central way of me reading these images, today there are so many people who are from the diaspora that are photographers now,” she said. “When families had to leave home, with disaster today, what do you take with you now? Photographs are what people are taking.”

Morning Edition’s Michel Martin visited Willis at New York University’s Tisch School of the Arts, where she teaches and leads the photo department.

Here are four takeaways from their conversation.

1. Willis’ upbringing shaped her love for photography

Willis grew up in North Philadelphia, Pennsylvania, where her mother had a beauty shop and kept what Willis calls: “the Black color wheel of magazines.”

The publications included Ebony, Jet, and Tan and featured images that influenced her growing up. Her father, a policeman and tailor, was also an amateur photographer.

2. Reflections in Black started as an undergrad paper

Willis was studying at the Philadelphia College of Art (the college merged with another institution to become the University of the Arts in Philadelphia in 1985. UArts closed its doors in 2024) when she asked a professor why Black photographers were missing from the history books.

“Where are the Black photographers?” she recalled. That question morphed into the monumental project that became Reflections in Black. She began her research by reading city directories.

“Because of segregation in the 19th century, I was able to identify with the asterisk the colored photographers … I created this list of 500,” she said.

She took that list to the Schomburg Center in Harlem, where she found some of the photographers’ images and created portfolios for each one. Later, with the help of Richard Newman, her “publishing angel,” the paper she wrote as an undergraduate grew into a book.

3. Frederick Douglass understood photography as biography

Frederick Douglass was one of the most photographed people during the 19th century. The writer and abolitionist is known to have had about 160 photographs and portraits made of him.

“I believe in reading his words that photography was biography,” Willis said. “We’ve not found a photograph of him smiling.” She emphasized Douglass himself collaborated with the photographer behind the lens in part as an effort to counter degrading images of Black people.

4. Willis searched for “The Exhibit of American Negroes,” which W.E.B. Du Bois organized for the 1900 Paris Exposition 

Members of the First Congregational Church in Atlanta pose outside the church in this photograph by Thomas E. Askew. The image appears in W.E.B. Du Bois’ albums of photographs of African Americans in Georgia exhibited at the 1900 Paris Exposition Universelle, and is included in Reflections in Black.

Wills first heard about the exhibit in the 1970s, when she went to the Library of Congress looking for photographs from it. She said staff told her the photographs didn’t exist.

Twenty years later, photographs from the exhibit were retrieved by a young Black man working in the archives. “They didn’t exist because they weren’t processed,” Willis told NPR.

Du Bois, she said, understood the importance of photography and often asked, “Why aren’t there more Black photographers, Black men studying photography?”

Can a ‘speed roommating’ event help you find a perfect match in L.A.?

Can a ‘speed roommating’ event help you find a perfect match in L.A.?

Inside a dim New Orleans-style bar in Hollywood, dozens of strangers mingle under the thump of pop music while nursing complimentary cocktails. Each person is sporting a name tag along with a personality sticker, or a few, that best captures their vibe. Neat freak. Plant parent. Night owl. Craft beer aficionado.

The scene reads like a friendly singles mixer, but listen to their conversations and it’s clear the chemistry they are hoping for isn’t romantic. They are here to find the perfect roommate.

Hosted by rental platform SpareRoom, the monthly “speed roommating” event connects people who are renting rooms with those who are looking for one in a low-key, in-person setting — no endless online profiles to fill out, no awkward interviews. Loosely based on speed dating, sans the timed interactions, attendees put on name tags indicating either “I need a room” or “I need a roommate” along with their ideal budget and neighborhoods. Then they wander freely. One woman passed out fliers for a furnished studio in downtown L.A. with air conditioning, a Murphy bed, an in-unit washer and dryer and streaming TV. Another woman showed people her rental on an iPad.

Pris Liora, 40, who was looking for someone to rent the extra room in her Koreatown apartment, didn’t prepare any questions for potential housemates, saying she just wanted to do a vibe check. Her only deal breakers? “No pets, no children, no cigarette smoking and no secret cocaine problem,” she says with a laugh.

With the average rent for a studio starting about $1,688 per month, $2,166 for a one-bedroom apartment and roughly $2,983 for a two-bedroom apartment in Los Angeles, according to Apartments.com, more people are embracing shared living arrangements. Rupert Hunt, founder and CEO of SpareRoom, says they’re doing so not only to cut expenses, but also to foster community. The company’s mixers can help spark those connections, he believes — they’ve been hosting speed roommating events in L.A. since June, following successful events in London, San Francisco and New York.

"There's something so immediate about the event," says Rupert Hunt, founder and CEO of SpareRoom.

“There’s something so immediate about the event,” Hunt says. “You meet 10 people in the time it would take you to meet one the traditional way.”

Hunt even found a housemate for himself at one of the mixers. “I love sharing,” says Hunt, who notoriously rented out two rooms in his New York City apartment for just $1. “I think I’m a better version of myself. I think I get a bit lazy if I’m living on my own.”

At the event, Aeris DeLeon, who was wearing a sticker with the phrase “foodie,” says her mother was the person who told her about the speed roommating event. The 25-year-old was temporarily living in Bakersfield but recently moved back home to L.A.

“It was just dead over there and I was just home sick, and it wasn’t really working out for me,” she says.

Upon arrival, attendees can pick out personality stickers with phrases like coffee addict, plant lover and early bird.

She decided to attend the event because it’s more “personable than just going on Craigslist or Facebook, and it’s the best [way] to weed out scammers,” she says. Her mission was to find an apartment that cost $1,300 a month max with someone preferably close in age.

James Caton, 68, was just getting started in his search for a room. After learning that his apartment building — where he’s lived for nearly a decade — might be sold, he jumped into action.

“To me, as soon as you find out, it’s better to go ahead and start looking for something,” says Caton, who attended the mixer with his childhood friend who was looking to rent a room.

SpareRoom’s speed roommating events are free with an RSVP, and each person receives two complimentary drinks along with a one month trial of SpareRoom premium.

Even if attendees didn’t find a roommate at the event, several of them continued their conversations late into the evening. Some even stayed for karaoke at the bar. It seemed that in a world where talking about finances can be seen as taboo, having a space to openly discuss rent prices, how to deal with nightmare landlords and housemates and other grievances was its own win, a moment when they could feel a bit less alone.
