Zodiac signs basics: Astrology 101 and the Language of the Stars

Astrology believes in a celestial map of stars and planets that dictates our lives. It is an ancient practice.

Developed around the 2nd century BC, the zodiac diagram charts 12 astrological signs.

These twelve symbols show how Earth, revolving on its axis, completes a yearly orbit through space.

Signs of the Zodiac

The 12 zodiac signs are the fundamental principle of astrology.

Each sign has its characteristics, colour, myths, and animals.

They all have an individual approach to life.

They have frustrating weaknesses and dynamic strengths.

The Western astrology zodiac is divided into twelve constellations.

Each one occupies 30° of celestial longitude and represents a specific sign.

Zodiac Signs basics

The signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.

Dates Of the Signs

The signs’ dates change yearly because the Equinox date isn’t precise.

This causes the start date of Aries to change, but it’s always between March 19 and 21.

Natal Chart

Astrological charts are magical, telling the story of who you were born to be.

At birth, every person is given a chart that astrologically defines all aspects of them.

Even down to their sensitive angles.

So what’s yours?

A Birth Chart might seem like it just tells your physical features and personality traits.

In reality, there’s much more than meets the eye.

For example, there’s something called “sensitive angle.”

Where it falls within their chart can change everything about an individual.

This is due to its intensity when combined with other elements.

Or how close planets may get at different points during life cycle phases.

For example, when a woman is pregnant.

Opposites and Elements

Each sign has an opposite, which results in 6 opposite couples.

Air and fire elements are opposites and water and earth are opposites.

Aries is opposite to Libra

Taurus is opposite to Scorpio

Gemini is opposite to Sagittarius

Cancer is opposite to Capricorn

Leo is opposite to Aquarius

Virgo is opposite to Pisces

Polarity – Positive and Negative

The zodiac signs are divided in half.

One part of the sign’s alignment can be positive or negative with different attributes.

The active or positive polarity signs are Aquarius, Libra, Leo, Gemini, Sagittarius, and Aries.

They are the odd-numbered signs, also called masculine signs, yang or expressive, and they make up the air and fire triplicities.

Cancer, Taurus, Virgo, Scorpio, Pisces, and Capricorn are the passive or negative polarity.

They are the even-numbered signs, also called feminine signs, yin or receptive, making up the water and earth triplicities.

The Three Modalities

The position of a sign in the season it is found is called the modality or mode.

There are three modalities: cardinal, fixed, and mutable.

Each modality has four elements assigned to it.

That’s why they are also known as Quadruplicates.

The Signs

Let’s look at each zodiac sign in more detail.

Aries – March 21- April 19

Traits: Gets bored easily

  • Always complies when dared
  • Easily forgets what made them angry 
  • Sees Life as a game they can win 

Aries is the first sign of the astrological zodiac.

In other words, they are independent and brave enough to take on life head-on.

They do not just observe life from afar, like some people do with their lives.

Aries also possess a fiery demeanour that comes out in every sense.

This fire shines through when an Arian talks, acts, or even reacts.

All because Mars rules over them as well!

  • All in or nothing. 
  • Stays home always 

Taurus is a dualistic sign with both an Earth and a Fixed nature.

They are extremely stable individuals.

They are intensely stubborn and loyal to others and their material possessions.

Taurus has Venus ruling it.

This means love for oneself and the desire to please those around them to provide comfort or luxury.

This can be seen through their tendencies towards food!

If you leave them alone, they will generally be peaceful.

However, they become tenacious fighters if provoked (perhaps by not listening).

They charge forward without fear.

Gemini is a sign that loves to communicate with themselves and others.

They are ruled by Mercury, the communicative planet that also rules communication in our physical world.

Gemini stands out as being able to think about things from two perspectives at once:

  • Their inner thoughts are communicated outwardly through interacting with other people or ideas.
  • Or what they read/hear externally, making them adaptable and flexible, just like their split symbol – twins!

Cancer: June 21 – July 22

Cancer is associated with domestic life/past, emotions, and other empathic abilities.

Their feminine energy helps them connect with these on a natural level.

Cancers have this hard exterior that covers up how very sensitive they can be internally as well.

Just like crabs carrying around their home on their back for protection from change when it comes too close to them.

All symbolic representations represent what cancer embodies: strength under vulnerability.

Leo has a fixed sign and is very confident.

They are also passionate and ambitious.

This can be seen in their love for the outdoors or how they entertain others.

The Lion’s pride does not falter when faced with adversity.

As long as that person remembers what Leo had done for him/her.

It only changes if you show no loyalty towards anyone who wronged them before.

Then, it shows forgiveness regardless of whether there was any wrongdoing at all!

They crave fairness in all of them.

They are an air sign.

Moreover, they enjoy intellectual pursuits as much as physical ones.

But justice is their main concern when it comes to these two realms.

  • Can’t be sure if they’re serious or joking
  • OK, with awkward silence
  • A leather jacket always fits.

Scorpios have a calm demeanour unless they are tested.

This is why the Scorpio’s symbol is that of the Scorpion, which may seem easy-going at first glance.

But if threatened, these creatures will sting with their strongest and quickest actions.

Their emotions are strong and fixed by design.

It should be no surprise to anyone else that they can tap into those unseen parts of our world.

Cancerians do, too.

Mars and Pluto rule over this sign during its astrological cycle, which occurs every 2 years.

You know how passionate things become for them when out on dates!

They stand ready with an arrow on their bow, aiming to penetrate darkness before it can take hold.

Their intuition guides them through life’s mysteries.

Society handed them down over time.

Capricorns enjoy being admired or respected.

Given that they are an earth sign, they view this as evidence of success.

If you want someone who gets things done with orderliness and doesn’t compromise on time, look no further than this.
