The Only Astrology Book You'll Ever Need summary

When most people ask for your star sign, or you check your horoscope in the paper or online, what you’re talking about is your sun sign, or zodiac sign. You probably already know yours.

This sun sign is determined by which zodiac constellation the sun was passing through at the time of your birth. For instance, if your birthday is between March 21 and April 19, your sun sign is Aries. The sun was in the particular constellation of Aries, and being born at this time of year has imprinted certain characteristics on you as a person. In other words, your sun sign colors how you experience life.

The 12 zodiac signs each have sets of traits attributed to them. Aries tend to be bold, passionate go-getters. Taurus people tend to be grounded, reliable, and loyal. Geminis are curious, clever, and sociable whilst those born in Cancer, nurturing homebodies.

If you were born a Leo, you might have a flair for drama and a love for the spotlight. Virgos can be meticulous, practical helpers. Libras strive for balance, harmony, and beauty. Scorpios are focused and passionate and can be quite protective. Sagittarians seek freedom and fun, whilst Capricorns are ambitious, disciplined achievers. Aquarians think outside the box, whilst Pisces dreamers are compassionate romantics.

Your sun sign might give you an insight into your ego, a sense of self, and part of your personality, but it doesn’t dictate your destiny. Instead, we can use these touchstone traits to help illuminate your relationship with yourself and your experiences. Discover the fire that fuels you as an Aries, the love that fills you as a Cancer, the ideals that inspire you as an Aquarius. Sun signs give you an elemental foundation, an astrological starting point that can reveal your core motivations, strengths, weaknesses, and patterns.

If you want, you can also dig a bit deeper into your sun sign. For instance, each sign is divided into three decans. These are 10-degree subdivisions that add a subtle nuance and flavor to your sun sign and are determined by the day you were born on your sun sign season. For instance, the first decan of Aries is influenced by Mars and might exude an extra boldness. The second strengthens passions for creativity. Meanwhile, the influence of Jupiter gives the third decan a boost of flexibility and intuition to those born late under the Aries sign. 

People born at the very beginning or end of a sun sign are on the cusp between two signs. For example, if you were born on March 21, the first day of Aries, you’re on the Aries-Pisces cusp. For these individuals, the sun hasn’t fully crossed into the next sign yet and they might exhibit a blend of both signs’ traits. In this case, for instance, the compassion and intuition of Pisces might balance some of the directness and zeal of Aries. 

Of course, sun signs are just the top of the astrological iceberg. Even with decans and cusps adding nuance and complexity to the 12-zodiac framework, there are many factors that come into play in a birth chart. Still, the sun sign is the core to reading your stars so we’ll spend a bit more time looking at how this might impact you.
