ICYMI, the practice of astrology is as complex as the celestial bodies it’s about (well, almost). There is so much more to this field than the run-of-the-mill, brief-ish horoscopes you read on a monthly, weekly, or daily basis. Of course, the most fundamental aspects of astrology are still the 12 Sun signs (a.k.a. your main zodiac sign) and the veeery specific personality traits that correspond to each.
Your individual Sun sign is based on where "the sun was in the moment you were born," says Narayana Montúfar, senior astrologer at Horoscope.com and Astrology.com. "This usually gets determined by the day, since the sun changes signs once a month. However, if a person was born on a day when the sun switches signs, their sun sign will be determined by the zodiac sign that the sun was in at the exact time of their birth." Noted! (And btw, that’s why "cusp signs," a.k.a. zodiac signs on the cusp of two different signs, don’t really exist.)
But the zodiac goes way beyond Leo’s unwavering confidence and Aquarius’s penchant for conspiracy theories. There's tons of complexity to the study of these signs, as well as the rest of the universe. "Astrology is an ancient art that was born from our ancestors following and studying the cycles of the planets and stars, and how these affect us here on Earth," explains Montúfar. So yeah, even though you may think astrology is really some kind of "fortune-telling" practice that predicts you how your day's gonna go (thanks, CoStar!), it's actually all based on energies dictated by the location of stars and planets at any given moment.
Two important tenets of astrology are "triplicities" and "quadruplicities" because they reveal even more about a specific sign's characteristics. Each zodiac sign falls one of four triplicities (fire, earth, air, or water) and one of three quadruplicities (cardinal signs, fixed signs, and mutable signs).
Here's exactly what you should know about the 12 zodiac sign’s dates and corresponding personality traits, according to an expert astrologer.
