Birth Charts
Here we break down the basics of what a birth chart entails, why they look like they do.
Including the layers of a birth chart that add to their complexity.
Let’s take a look at Birth Charts.

What Are Birth Charts?
What are Birth Charts?
A natal birth chart is a map showing the positions of the planets at the time of someoneās birth.
This is a birth chart of Hollywood star Brad Pitt.

This map is from our vantage point on earth.
A chart is taken for any moment in timeāpast, present or futureāwhich allows for observations of the past and present, as well as predictions of future events.
Some of the other names for a birth chart include aĀ natal chart,Ā star chart, andĀ horoscope. Donāt worry, though; theyāre all the same thing. Then is no right or wrong term to use.
On this website, we generally use both birth chart andĀ natal chart.
Throughout an entire lifetime, a personās chart will never change.Ā However, the influences acting upon the chart are continuously evolving, and these forces bring change to an individualās life.
The chart shows detailed information the positions of the sunĀ sign, moonĀ sign, rising sign, all of the planets, and potentially other celestial objects; all referred to as the nativeās āplanetsā when they were born.
Transit charts can show things like MercuryĀ Retrograde.
Originally, birth charts were always hand drawn and calculated manually. Even though this technique is still practised today, most chart calculations are done automatically using online software.Ā Most online software accounts for daylight savings and time zone variations.
Birth Chart Creation
With all birthĀ charts and natal chart events, you need to have a birth date, birth city and birth time (aka birth data).
- The birth date is the most important.
- The birth city is normally to identify the time zone and whether daylight time is involved in the calculations.
- The birth time needs to be as close to the exact time as possible.

What Astrological Birth Charts Look Like
Because the charts are often calculated automatically online, lots of different websites use different styles.
Below are some styles of birth charts that exist across other astrology websites.
These are styles ofĀ charts and not necessarily TYPES of charts.

If you do not know what your birth chart is, you can use our ownĀ Birth Chart Calculator which will tell you what your Birth Chart is,Ā plus all the other planets as well.

Birth Chart Meaning
Below is a slideshow explaining the construction of a birth chart that tells about the natal chart and how it is made up.
A Natal Chart
So firstly, we have a basic chart wheel. The twelve subdivisions of the circle, or āwedges of the pie,ā represent the 12 signs of the zodiac.

360° Degrees
The circleĀ divides into 360 degrees; each sign occupies 30 degrees, making up a total of 12 signs.
Each degree is equal to 60 minutes (minutes here is a unit of measurement, not of time).

Astrology Signs
Now, we add the astrological symbols.
Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.
The symbols go around the chart COUNTER-CLOCKWISE. The reason for this is because we see the stars and signs from the earth.
(Although, I think it works fine clockwiseā¦..just saying)

Astrological Elements
The main difference in this one is that the symbols are now in their respective elemental colours.
- The red symbols are the fire signs.
- The green symbols are the earth signs
- The yellow symbols are the air signs
- The blue symbols are the water signs.

Astrological Houses
As well as 12 signs, the Natal has 12 houses as well, which are represented by the 12 numbered āwedgesā that divide the chart.
These houses represent focal areas of expression in the birth chart. The size of the houses and house positions varies depending on where in the world you were born and at what time.
Also, the house system (like Placidus) will also determine how the houses appear on the chart.
Note: An unknown birth time would affect the accurate data of an astrology chart, although some software programs can help people who don’t know when they were born by providing partial information.

Astrological Planets
Once you have created your birth chart, then you will then have all of the planet placements as well.
The standard will contain the personal planets.
- Sun
- Moon
- Mercury
- Venus
- Mars
Also then you will have the outer planets
- Jupiter
- Saturn
- Uranus
- Neptune
- Pluto
You can add sometimes add asteroids like Vertex, Chiron, Juno and so forth.

Astrological Aspects
Once you the planets, there is normally a series of lines interlinking the planets of varying lengths,Ā angles and colours.
The lines connecting the planets are known asĀ Aspects and are very important inĀ understanding the relationships of the planets in a personĀ chart.
