Before learning about the other aspects of astrology, you must now learn about how a horoscope is cast and how to read it.
We are not going into the teaching of the complicated mathematical aspects of calculating the planetary positions, lagna etc.
Now a days even the astrologers depend on the computerized software.
From the practical point of view of learning the basics,
you only need to know 'how' the birth chart is cast and how to read and understand it.
The horoscope is the picture of the heavens at the time of one's birth.
It shows in which rasis {aka signs},
the 9 planets are positioned.
It also shows another important aspect of astrology called the Lagna {aka the Ascendant}.
It plays a major role in analyzing an individual's life.
The ascendant is calculated based on your place and time of birth and varies from place to place.
This is because of the difference in latitude and longitude, and the sun rise time.
Lagna is called your individual 1st house.
It must be noted that the lagna may fall in any of the 12 rasis {signs}.
The counting of your individual houses is always done from the lagna.
You will learn about the houses and their importance in the next lesson.
The position of the planets on any given day and time is calculated from the 'ephemeris', called Panchang,
and the horoscopes are made accordingly.
It is not some kind of a mystic charting of planetary names in a chart.

Difference in measuring the planetary positions –
Vedic vs. Western astrology
Vedic Astrology follows the Niryana {aka the 'sidereal zodiac'}, --
where as the Western Astrology follows the Sayana {aka the 'tropical zodiac'}.
It's a highly complicated astronomical subject.
Briefly the fundamentals are as follows.
The placement and especially the degrees of the planets in the birth chart of a person made according to western astrology differ considerably from the birth chart made according to Indian {aka Hindu, Vedic} astrology.
According to the western sun signs
Sun enters Aries on 21st of March --
but according to our {Indian} calculations
{Sun} enters Aries on the 14th of April.
So there is a '24 degrees difference'.
The Western or “Sayana” zodiac system
makes calculations and predictions based on
the present position of the planets
from a zodiacal point of view or
AS OBSERVED BY THE SATELLITES.
Our system is called “Nirayana” or Indian System.
In the Nirayana system, the planetary positions
are AS SEEN FROM EARTH TODAY
by taking into account the tilting of the North pole by making corrections accordingly.
If you take the standard globe available in the market
and keep it on the table,
you will observe that the North and the south poles are not exactly 90 degrees vertically up but are tilting.
This inclination is about '23+ degrees' to the east and it greatly effects astronomical calculations.
See the picture.
This 'inclination' is caused due to the shifting of the 'vernal equinox', which happens because of the West to East 'spin of the earth' around its axis.
While playing tennis or table tennis,
if you give a sideways spin to the ball
it not only spins in the direction of the spin but also swerves or swings in the air.
Similarly
as the earth is spinning towards the east on its axis,
'the North Pole' is slowly tilting towards the east.
This difference between the longitudes of the starting points of the sidereal,, and tropical zodiacs,, is called Ayanamsha.
The starting points of the sidereal and tropical zodiacs
coincides once in every 25,800 years approximately.
According to accurate scientific calculations,
the present shift started in the year 285 AD,
i.e. 285 years ago the North Pole was perfectly vertical at 90 degrees.
The most accurate method of calculating this ayanamsa
is the Chitrapaksha ayanamsa,
popularly called Lahiri Ayanamsa.
The ayanamsa calculations of the Greeks like Hippocras and Ptolemy were wrong.
The western scientists are officially “credited” with the “discovery” of the accurate shifting of the earth's equinox towards the end of the 19th century.
They found it to be 50″.
It was actually known to the Hindu astrologers long before that.
Varahamihira, the famous astrologer in the court of Vikramaditya in the year 57BC, clearly mentioned in his work Pancha Siddhantika,
based on our ancient Siddhantas,
that the ayanamsa is 50.32 seconds.
This is the most accurate one.
The difference between the Sayana longitudes
and the Nirayana longitudes of Planets
is called “Ayanamsa” or precision.
This Ayanamsa difference is the exactly calculated shift or inclination of the 'equinox'.
..
For example on this day on 23rd June 08,
the exact Ayanamsa or the tilt is 23:58:43 degrees.
From the longitude position of the planets in the Zodiac at this moment, when this Ayanamsa is deducted, we get the 'correct longitude' of the planets (as applicable to our position on earth).
In the western system
as this 'shift of the equinox' is NOT taken into account,
all the planets are about 24 degrees ahead.
The picture given bellow will give you an idea.
The position earth |shown at the bottom in the picture| is with equinox tilted correctly i.e. corrected Ayanamsa.
If you are born on the dark spot see the position difference of Sun if Ayanamsa is not corrected.
We are more concerned as to where the planet is vis-à-vis our position on earth and not as seen by a satellite!
And we definitely don’t follow the equinox position of 285AD !!

..), your personality is still forming and maturing. You really can't judge the chart until you've experienced almost half of it?
