Aquarius Compatibility

Aquarius is most compatible with Gemini and least compatible with Taurus. In astrology, a sign’s element plays a big part in who they’re most compatible with. As an air sign, it’s no surprise that Aquarius gets along swimmingly with Gemini and Libra , the other two air signs of the zodiac. With Gemini’s natural wit and intelligence and Libra’s active spirit, Aquarius has no shortage of things in common with either sign. Aquarius also has good compatibility with Aquarius , Sagittarius , and Aries , and moderate compatibility with Leo . ^{[7]

- On the flip side, Aquarians are generally not compatible with Taurus , Cancer , Virgo , Scorpio , Capricorn , and Pisces .
- They especially struggle to build lasting relationships with other fixed signs, like Taurus and Scorpio. Since all three of these signs are very stubborn and set in their ways, it can be easy to get into disagreements…and not be able to get out of them.

What is the most common zodiac sign?

Virgo is the most common zodiac sign . However, depending on the year and region, Scorpio and Leo are also cited as very common zodiac signs. Back to Virgos , our most popular sign, their era starts on August 23rd and ends on September 22nd. Seeing as July through October is the most popular window for babies to be born in the U.S., it’s no surprise that the patient, hardworking, and analytical Virgo is the most common birth sign out there. ^{[11]

What about the Ophiuchus zodiac model?

Download Article

If you follow the Ophiuchus astrological model, Capricorn is the rarest sign. In Western astrology, each astrological constellation is assigned to a 30-degree section of a circle that represents the Sun’s path. While the Ophiuchus constellation doesn’t get its own piece of the pie, it does pop up on the Sun’s path, and it was included in astrological models in some ancient cultures. If you were to factor it into the normal 12-sign cycle of astrology, it would shift each date range by about a month. ^{[13]

Research source} So, Capricorn would roughly slide into Aquarius’s spot, making it the rarest zodiac sign overall.
- Here’s the ranking of signs from rarest to most common , using the Ophiuchus model:
  - 1st (rarest): Capricorn (January 20 - February 16)
  - 2nd: Pisces (March 11 - April 18)
  - 3rd: Sagittarius (December 17 - January 20)
  - 4th: Aquarius (February 16 - March 11)
  - 5th: Aries (April 18 - May 13)
  - 6th: Taurus (May 13 - June 21)
  - 7th: Cancer (July 20 - August 10)
  - 8th: Ophiuchus (November 29 - December 17)
  - 9th: Libra (October 30 - November 23)
  - 10th: Scorpio (November 23 - November 29)
  - 11th: Virgo (September 16 - October 30)
  - 12th: Gemini (June 21 - July 20)
  - 13th (least rare): Leo (August 10 - September 16)

Why are some zodiac signs rarer than others?

Download Article

Some zodiac signs are rarer than others because birth rates are lower in those months. Since zodiac signs are based on the month in which someone was born, lower birth rates in certain times of the year will affect zodiac signs. Birth rates themselves can be impacted by a lot of things—like holidays, weather patterns, and world events. For example, winter birthdays are often considered to be less common, since many people try to plan their pregnancies so that they’re not giving birth during the holiday season. ^{[14]
X
Research source}
- As a result, winter zodiac signs (like Aquarius) tend to be rarer.
- Conversely, it’s possible that more couples are intimate during the winter holiday season, which creates a higher birth rate in the warm summer months. So, summer zodiac signs (like Virgo and Leo) are more common!

Pisces are often shy but very romantic. Pisces are born from February 19 to March 20. They are very emotional (whether the emotion is happy or sad). Oftentimes they are very tough (they love hugs).

Question

If I followed Ophiuchus and I'm a Taurus, could I be an Aries?

Community Answer

No, not really. Your zodiac sign relies on your birthday, not someone you've followed, and you can't change your date of birth.

Question

What are Virgo and Taurus like?

Community Answer

Taurus tends to be stubborn. Taurus can fight and is quick to anger, so if you say they are wrong, you have a challenge ahead of you. Virgo tends to be thoughtful most of the time and is the one that is willing to guide you. Virgo is usually quite nice. Just remember that these are not hard-and-fast rules, merely tendencies (because there are many other astrological indicators in a person's life, not just the sun sign).
