In astrology, there is a procedure known as rectification. It involves a reverse analysis of all events in a person’s life, their character, and habits. This is quite logical – if an astrologer can determine a person’s future and past events based on their date of birth, then in reverse order, they can clarify the person’s time of birth.
To create a horoscope independently, specialized knowledge is still necessary, without which obtaining accurate values is impossible. There are several methods for creating a horoscope. The first method is the simplest – to use the services of various online tools. There are many different programs available that can create a natal chart. However, this option does not guarantee accurate values, as the human factor plays a crucial role in this work.
The next option is to create a natal chart independently. Generally, the methodology involves calculating the positions of various planets, the Sun, and the Moon at a specific time. To calculate the coordinate plane, the ecliptic longitude of each celestial body is determined. The ecliptic in the horoscope is a circle divided into 12 sectors of 30 degrees each, corresponding to each zodiac sign. Based on the ecliptic longitude, it is determined which sector a particular celestial body falls into. For example, if the Moon was at the 45-degree mark of ecliptic longitude at the moment of a person’s birth, it means that at that time, the Moon was in the sign of Aquarius. The positions of other bodies are calculated in the same way.
The next step is to calculate the angular distance between the planets and stars. If the distance corresponds to the magnitude of one of the astrological aspects, it can be said that the planets and stars are in aspect to one another. In the horoscope, planets in aspect are connected by a straight line. We have discussed the geographical location of the person’s birthplace – it will be important in the stage of creating the characteristics of the celestial sphere for a specific locality. It is necessary to calculate several values of intersection with the horizon: Ascendant, Descendant, points of intersection with the midheaven and the nadir. All this data is entered into the cosmogram, which is a complete picture of the positions of celestial bodies at the moment of a person’s birth. It can be confidently said that at this stage, the construction of the horoscope is completed.
As can be seen, this is a very meticulous job that requires a significant amount of time and effort. Specialized knowledge is necessary to navigate freely in compiling these values and their subsequent characterization. That is why creating a horoscope for free and without special knowledge poses some difficulty for many people.
Creating a horoscope using ephemeris tables
But how to create a horoscope without special knowledge? There is another option – using ephemeris tables. For this, you will need a world atlas, house tables, ephemeris tables, and a calculator.
Ephemeris are special tables that indicate the mutual positions of the planets for each day. In fact, all calculations have already been done for you. The most common tables are the “Rosicrucian Tables,” which cover the entire 20th century. Ephemeris tables can be found in specialized publications.
House tables will be needed to determine the axes of the horoscope and the cusps of the houses. Such tables can be found in abundance online, with some of the best being Placidus tables.
An atlas is necessary to calculate the exact geographical coordinates of the person’s position at the time of birth. Although nowadays, one can also use online resources, such as Google Earth. This program can provide the most accurate information. A calculator will be needed to perform the calculations indicated in the ephemeris tables.
