Are you a horoscope skeptic? Get ready to believe! While these signs go by many names—including astrological, zodiac, or sun signs—they can impact your life in legitimate ways. That’s especially true when it comes to your romantic compatibility, according to professional astrologer Rachel Lang.
Here’s how it works: Your sign is determined by the position of the sun at the time of your birth. According to astrologers, your sun sign is immensely important when it comes to who you are and how you mesh with other people. “Your sun sign is your juice,” Lang told Brit+Co. “It gives the basis for your personality.”
In addition to certain personality traits, each sign is linked to an element (either air, fire, earth, or water) as well as qualities that can be fixed, cardinal, or mutable. The compatibility of those elements and qualities can reveal whether or not you’ll hit it off with a romantic interest. In other words, if your sign’s element jives with your partner’s sign’s element, you could have great potential compatibility. (This is your zodiac sign’s most attractive trait, by the way.)
Of course, that’s not the only way to predict the success of a relationship. “Your sign shows who you relate with, feel at home with, and get along with,” Lang said. “But there’s astrology—then there’s upbringing, life factors, and beliefs that help determine compatibility.”
Translation? If you’re in a relationship with someone whose sign is technically incompatible with yours—such as the zodiac signs that should never, ever date each other—don’t sweat it! Sometimes, a relationship between incompatible signs can even be positive. “We all seek relationships with tension,” Lang said. “That’s why you can have a relationship with someone of any sign: We all have strengths and weaknesses and things that make us different. We grow through challenge and conflict.”
We hate to be the bearers of bad news, but your zodiac sign probably just changed. So before you settle down with your potential soulmate, you might want to double check those shifting star signs.
