In astrology, your natal chart (sometimes called birth chart) is a graph that shows the positions of the planets and astrological houses in the sky at the moment of your birth. Your natal chart is much more detailed and accurate than your horoscope. A popular horoscope considers only the position of the Sun, whereas your natal chart includes hundreds of pieces of data. Mark Twain once said: The difference between a good word and the right word is like the difference between fire and firefly. Similarly, your popular horoscope may hold some hints of truth, but your natal chart tells us the real story of your natural personality.
Analyzing the planetary positions and relationships in your natal chart affords a remarkably profound and revealing glimpse into your natural character, with its inherent strengths and weaknesses. Among other things, your natal chart will tell you:
A) what type of partner and relationship you seek and will be best matched with,
B) what type of job or career your natural strengths and weaknesses are best suited for, and
C) obstacles that need to be overcome in your life. Most importantly, your natal chart will help you to understand your desires, motivations, and why you are the way that you are.
For a natal chart to be accurate, we must know the exact positions of the stars at the exact moment of your birth. Since the houses of the zodiac revolve one degree every four minutes, an accurate time of birth is necessary to determine your Ascendant sign and some planetary
aspects. Although you can generate a natal chart without these highly time-sensitive positions included, to have a more accurate chart that is generated with an exact time and place of birth.

In astrology, a
natal chart is a stylized map of the universe with the "native" (the individual or subject to be studied) at the center. It is calculated for the exact time and location of the
Birthday for the purposes of gaining insight into the natives personality and potential. Commonly used alternative names for the natal chart include
birth chart horoscope natus nativity radix geniture and
genethliac chart among others. The chart shows the positions of the sun, moon, planets, and potentially other celestial objects, all referred to as the natives "planets," within the frames of references defined by the
astrological sign and
Astrological houses
The accurate birth time (generally agreed upon as the first breath or intake of air) and location are necessary for the calculation of the exact degree of the signs that are rising, setting, culminating up, and culminating down, known respectively the
ascendant (or "rising sign"),
Descendant (astrology) [[Midheaven|medium coeli]](or "midheaven"), and
[[imum coeli]](or "lower midheaven"). These degrees, also known as the
angle (astrology) are essential for mapping the positions of the natives twelve houses.

The picture to the above-right is a modern example of a natal chart as a modern Western
astrologer would most likely view it (though there are variants depending on the specific astrological tradition that the astrologer follows and/or their personal preferences). In this example, a horizontal line through the middle of the chart roughly corresponds with the horizon, with the left side being the place where objects on the ecliptic are rising in the east (the ascendant). The sun is seen near the bottom, since the chart was made for midnight, in the sign Capricorn, since it was made for January 1.
The design, along with the symbols/glyphs used in the chart, can vary widely; some choose to include the Zodiac wheel, while some do not. Also, charts do not have to be round—following the
Hellenistic Ancient Rome medieval and/or
Vedic astrology , they can be square as well.
The
astrological aspects (such as
Conjunction (astronomy) or
Opposition (astronomy) among others) are delineated in the center of the chart. The twelve signs of the
Zodiac are located at the outer portion of the chart wheel; similarly, twelve segments of arc form astrological
House (astrology) which are said to have significance for different areas of life. There are many different systems for calculating the houses. The sample chart uses a
quadrant housesystem of house division whereby the
angle (astrology) of the chart divide the chart into four
quadrant with three houses within each quadrant, and in which the houses usually include portions of more than one astrological sign. Each quadrant has an
angular house which includes one of the
angle (astrology) of the chart; a
succedent house follows this, with a
cadent house at the end of the quadrant.
Place and time of birth
Because the Sun, Moon, planets, and primary angles in the sky are constantly in motion relative to the earth, as each second passes the natal chart/
horoscope is changing (albeit slowly) and a new chart is created for every moment at each location. A natal chart is extremely personal and unique, depending on the specific date, exact time, and precise location of the birth. Even the birth charts of twins are often slightly different because one of the twins is usually born a few minutes apart from the other (see also:
astro-twin .
The time of birth can usually be found on the
birth certificate in many countries. In some instances, however, the birth times are rounded off by the nurse or doctor that is present to the nearest half or quarter-hour, thus rendering the time only approximately correct. Because of this fairly common practice, the parents should always remember to note the
exacttime of the childs first breath and not rely on the time given on the birth certificate in the event that they ever plan on having a precisely accurate natal chart calculated for their child. An accurate time of birth is virtually useless if the exact location of birth is not known.
Most charts are
geocentric that is based on the Earth. However, there is no reason in theory why a chart cannot be created for another planet. Some astrologers use
Heliocentric Astrology - Sun centered - charts. These are theoretical constructions and have a different interpretation to geocentric natal charts. Charts based on other planets would need all the points recalculating from that point of view; for example, "Jovocentric" would be a Jupiter centered view.
Erecting the natal chart
Once the astrologer has ascertained the exact time and place of the subjects birth, the local
standard time (adjusting for any
daylight saving time or war time) is then converted into
Greenwich Mean Time or
Universal Time at that same instant. The astrologer then has to convert this into the local
sidereal time at birth in order to be able to calculate the
ascendant and
midheaven The astrologer will next consult a set of tables called an
ephemeris which lists the location of the sun, moon and
Planets in astrology for a particular year, date and sidereal time, with respect to the
vernal equinox or the
fixed star (depending on which astrological system is being used). The astrologer then adds or subtracts the difference between the longitude of Greenwich and the longitude of the place in question to determine the true local mean time (LMT) at the place of birth to show where planets would be visible above the horizon at the precise time and place in question. Planets hidden from view beneath the earth are also shown in the horoscope.

Astrology]]
The horoscope is then divided into 12 sectors around the circle of the ecliptic, starting from the eastern horizon with the
ascendant or rising sign. These 12 sectors are called the
House (astrology) and numerous systems for calculating these divisions exist. Tables of houses have been published since the 19th Century to make this otherwise demanding task easier.
Placements of the planets
Having established the relative positions of the signs in the houses, the astrologer positions the sun, moon, and planets at their rightful celestial longitudes. Some astrologers also take note of minor planetary bodies, fixed stars,
asteroid (for example,
2060 Chiron and other mathematically calculated points and angles such as the
vertex (astrology) equatorial ascendant, etc. Many astrologers also use what are commonly referred to as
[[Arabic parts]] (or
Greece Lots), the most common of which is the
Part of Fortune (Pars Fortuna).
Aspects
To complete the horoscope the astrologer will consider the
astrological aspects or relative angles between pairs of planets. Certain aspects are considered more important than others. Those generally recognized by the astrological community are
Conjunction (0°),
Opposition (180°),
Square (90°),
Trine (120°),
Sextile (60°),
Semi-Square (45°),
Sesquisquare (135°), and
Quincunx (150°). Understandably these aspects are more significant when they are exact, but they are considered to function within an
orb of influence, the size of which varies according to the importance of each aspect. Thus conjunctions are believed to operate with a larger orb than sextiles. Most modern astrologers use an orb of 8° or less for aspects involving the Sun, Moon, and Jupiter and smaller orbs for the other points. Some astrologers, such as practitioners of
Cosmobiology and Uranian astrology, use minor aspects (15°, 22.5°, 67.5°, 72°, 75°, 105°, 112.5°).
Rectification
When the birth time is known not to be precise, astrologers will try to find the exact time by using a technique known as "Rectification of The Birth Time". The starting point of any rectification is always the known (inexact) birth time. A list of important events and the dates they took place in the life of the native is collected by the astrologer. The death of parents and the date someone emigrates to a foreign country are among the events that will register most strongly when the technique is used correctly. Important accidents and surgeries usually offers strong registration also. For each event the astrologer will calculate Solar Arc Progressions and Directions, Converse Solar Arc Progressions and Directions, and Transits, comparing all these charts with the Natal. The angles are then replaced in the degrees responding to the exercises. According to Dane Rudhyar and several other proponents of the rectification of the birth time, complete accuracy is only possible when the range of doubt regarding the exact time of birth is no more than one hour. After that the possibilities of accuracy drop dramatically and the exercise should not be tried. Currently, many astrologers unacquainted with the meaning and/or techniques involved in the calculation of a rectified chart tend to call any chart calculated with no known starting point for a birth time a rectification. This is incorrect, for those charts are nothing more than speculative astrological charts with no base in reality. A rectification, like the name suggest, is a recalculated chart, always taking in to consideration its starting point, the alleged, inexact, birth time.
Interpretation
Once the natal chart has been constructed the process of interpretation can begin. This is a branch of astrology known as
natal astrology which involves building a complete picture of the personality of the subject, or native. Interpretation involves two main steps - chart weighting and chart shaping.
Chart weightinginvolves noting the distribution of
astrological signs and
House (astrology) in the chart, and the significance of this to the overall personality of the native. Signs are assessed by element (Fire, Earth, Air, and Water) and by quality (Cardinal, Fixed and Mutable). Houses are assessed by the significance of Angular, Succedent and Cadent houses.
Chart shapinginvolves assessing the placement of the planets by aspect and position in the chart, and noting any significant patterns which occur between them. This involves noting significant aspect patterns (or groups of aspects), which may appear in the chart and any other patterns, such as
Marc Edmund Jones
The solar chart
The solar chart is a natal chart erected when the date of birth is known, but not the time of day.
[Robert Pelletier & Leonard Cataldo Be your own astrologer p62, Pan Books, London, 1984] The position of the sun at midnight or noon is taken as the time of birth, and the position of the sun, moon and planets plotted in the chart for that time. This leads to a fairly accurate picture of their position (with the exception of the moon), as most of the planets do not move much in the course of one day. The aspects between each of the planets (except the moon) can therefore be plotted with a high degree of confidence. The suns position is taken as the
ascendant of the chart and equal sized houses of 30 degrees each are used; or alternatively, the
sunrise chartcan be used, with the suns position at sunrise at the latitude in question taken as the ascendant.
[Maritha Pottinger Astro-essentials, pp390-1, ACS Publications, San Diego, 1991]
Although the solar chart is deficient in that it cannot show the ascendant, midheaven or the houses with any accuracy, it can nevertheless provide a fairly accurate profile of a persons character from examining the position of the planets alone.
