Generate Your Natal Western Astrology Chart

Start Your Journey To Self-Discovery Among the Stars By Plotting Your Birth Chart Today

You probably already know your zodiac sign, even if you aren’t very interested in western astrology. I think it’s safe to assume that nearly everyone has clicked on “free horoscope” at least once.

But did you know that your birth chart contains additional insight that reaches beyond the cliche life lessons crammed in sun sign horoscopes?

What is a natal chart?

An astrological chart is a snapshot of the heavens at the moment of your birth that focuses on the position of the planets as viewed from your birthplace. The line that stretches across the width of the chart represents the horizon (labeled AC for ascendant and DC for descendant).

Astrologers believe that the birth chart represents the most subconscious & constant driving forces in an individual’s life – the underlying foundational components of their personality. Many believe this chart is a spiritual tool which holds the secrets to an individual’s past lives, karmic history, & future.

According to Sara Coughlin’s interview with astrologer Janelle Belgrave, a natal chart contains all sorts of clue to an individual’s “personality, drives, fears, parental relationships, siblings, children, psychological patterns, and more.”

Your birth chart is more unique and individual than your birth date alone!

Aside from your zodiac sign (what astrologers call your sun sign), you also have a moon sign and a rising sign. Your sun, moon, and rising (or ascendant) signs make up what western astrology recognizes as The Big Three.

The placements of the planets Mars, Venus, Jupiter, Uranus, Neptune, Saturn, and Pluto all traditionally have individual and collective impacts on a chart too.

It might sound overwhelming at first, but generating your birth chart is easy with modern technology.

Be sure to print or screenshot your chart and keep it handy for the next time you run across an astrology book or article.

Follow these steps to plot your personal natal chart!

To get started generating your natal chart, you’ll need three things:

  1. Date of birth (day, month, and year)
  2. The name of the city or town where you were born
  3. Your exact birth time if at all possible (in local time; the computer will calculate daylight savings time and time zones)

Once you have your exact birth time, date, and place, follow the instructions below for drawing up your chart!

A Note About Birth Times and Locations

The location you were born and the exact time of your birth are both necessary to generate the most accurate natal chart possible. Because various planets and points sometimes change zodiac signs at rapid speeds, absent birth information or an inaccurate date and time entry may lead to incorrect chart placements.

Being just four minutes off can change placements by entire degrees and distort the calculations necessary for most house systems. This means that having the wrong birth time could result in you reading for unreliable placements you may not actually have.

Chart aspect patterns (grand trines, t-crosses, cradles, etc.) and planetary aspects (squares, oppositions, conjunctions, etc.) should also be considered unreliable unless the natal chart is generated using an exact time.

If you’re missing or unsure of your birth time, check out these tips or look into generating a rectification chart.

Ignore the partner setting. It won’t do anything with the options I’m having you select. Also leave the chart type, chart drawing style, and start date options as the default.
