Sun sign astrology
New millennium astrological chart
Sun sign astrology is the form of astrology most commonly found in many newspaper and magazine columns. It is a simplified system of astrology which considers only the position of the Sun at birth, which is said to be placed within one of the twelve zodiac signs. This sign is then called the sun sign or star sign of the person born in that twelfth-part of the year.
Sun sign astrologers take this basic twelve-fold division and relate all the current movements of all the planets to each other, using traditional rules to divine meanings for each sign separately. Because the Moon has the fastest apparent movement of all the heavenly bodies, it is often used as the main indicator of daily trends for sun sign astrology forecasts.
As with all astrology, it is considered pseudoscience by the scientific community.
Although William Lilly in the 17th century was the first newspaper astrologer sun sign astrology was not invented until 1930. The astrologer R. H. Naylor was claimed by his newspaper to have predicted the crash of the R101 airship. This led to pressure on Naylor to come up with a simplified system of astrology suitable for a newspaper column. After some experimentation, Naylor decided on sun signs.
Sun signs 
The following table shows the zodiac names in Latin, with their English translation and the individuals' names. It also shows the element and quality associated with each sign. The starting and ending dates of the sun sign are approximate, as they may differ from one year to another (by a day or so), due to the fact that the earth's orbit around the sun is not synchronous with earth's rotation (one year does not comprehend a whole number of days). The exact date and time of sign entrance/exit must be obtained with appropriate software or with the help of an ephemeris.
