Intrinsically linked with astrology, a horoscope is simply a chart or diagram that reperesents the positions of the Sun, the Moon, the planets, astrological aspects and 'angles' from the time of an event (e.g. your birth). Horoscopes are themselves are therefore an interpretation, by an astrologer, of how celestial events relate to your star sign for your birth date - a method of divination relating to events about the point in time it represents.
The word ' horoscope ' is derived from Greek words that mean "a look at the hours" (horoskopos). There are other common names for the horoscope including astrological charts, astro-charts and star charts.
How do you create a horoscope:
The astrologer first has to find the exact time and place of the subject's birth, or the initiation of an event.
- Convert the date and times into GMT (Greenwich Mean Time or Universal Time) and then into sidereal time
- Consult an 'ephemeris' - a set of tables that show the position of the Sun, Moon and planets for the year, the date and the sidereal time - in respect to Northern hemisphere vernal equinox or the fixed stars
- Subtract difference between longitude of Greenwich and the longitude of the place in question to determine the true Local Mean Time (TML) at place of birth to show where visible planets we above the horizon
- Divide the horoscope into 12 equal sectors around the circle of the ecliptic. You start from the Eastern horizon (rising sun) - these are then called the houses
- The houses make up the chart framework (12 houses) and the signs of the Zodiac are then superimposed
- Setting the Ascendant - the Longitude is necessary in order to determine the position of the Ascendant because horoscopes use local time
- Planetary placements - Once the relative positions of the signs in the houses are sorted, the astrologer positions the sun, moon, and planets at their rightful celestial longitudes
- Completing the horoscope the astrologer will consider the aspects or relative angles between pairs of planets.
So we have now covered in brief how astrologers develop a horoscope, what does it tell? Astrological readings that have been prepared as above may present you with 'personality profiles' that contain relationship advice, when to make financial decisions in order to maximise success and even future predictions. However, usually it is close personal advice that wins the day rather than predictions.
A full, private and professional reading can end up being extremely detailed and packed with details about interactions between various astrological elements.
