This Zodiac Sign Is The Rarest Of Them All, According To Research

While all 12 zodiac signs are no better or worse than the rest, there is one sign that has bragging rights for the rarest zodiac sign of them all. And yes, that means there's another sign that's most common too.

In order to figure out which zodiac sign is the rarest, we have to look at the most up to date birth data1. And according to the CDC's annual U.S. population report, the month with the least number of births in 2022 was February.

And that can only mean one thing: The rarest zodiac sign is none other than Aquarius.

Aquarius is the 11th sign of the zodiac, making it the second to last sign of the astrological year. It's represented by the Water Bearer or sometimes simply by three squiggly lines.

An air sign ruled by Saturn in ancient astrology and Uranus in modern astrology, Aquarius energy is eclectic, creative, and forward-thinking. It represents fixed air, so it has a keen ability to see the big picture and help push humanity in the right direction.

Because it's depicted as the Water Bearer (and its name literally has aqua in it), many people confuse Aquarius for being a water sign, but Aquarius' task is to provide a container for those emotional waters and subsequently allow those waters to flow out and water the soil for future growth.

According to astrology expert Imani Quinn, Aquarius can do well with a number of astrological signs, but when they match up with their opposite sign, Leo, they combine fiery passion with progressive air for strong forward motion.

And as an air sign, Aquarius will tend to naturally click with the other air signs, Gemini and Libra, or even another Aquarius.

Based on the aforementioned CDC data, the rarest zodiac signs are Leo and Virgo, with August being the most common month to give birth in the U.S. (July is the second most common.)

Leo season runs from July 23 to August 22, and Virgo season kicks off immediately following Leo season until September 22. And if Aquarius' rarity has to do with conception patterns, there might be something to say about the holiday season coupled with cozy, wintry vibes encouraging people to conceive.

Leo is a fixed fire sign ruled by the sun and is known for being regal, proud, and loyal. These folks are most compatible with the other fire signs (Aries, Sagittarius, or another Leo), as well as its astrological opposite—and the rarest sign—Aquarius.

If you've ever caught word of a "13th zodiac sign," aka Ophiuchus, you might be wondering where it comes into play. Also known as the Snake Bearer, this constellation is considered by some to be the rarest sign (from November 29 to December 17).

That's because back in 2016, NASA published a post mentioning a 13th constellation that the sun passes through every year, between Scorpio and Sagittarius. But according to the AstroTwins and many other Western astrologers, Ophiuchus is just a constellation—not a zodiac sign.

In fact, NASA even issued a statement to reassure people that they didn't create a new sign, highlighting the difference between astronomy and astrology.

As the twins explain, "The zodiac we use for modern 'Tropical' horoscopes is based on our view of the sky from the earth, divided into 12 pieces, and oriented by the four seasons. While the individual zodiac signs are named after the constellations, their physical placement is not based on those actual constellations in our modern form of astrology."
