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.

The exact date and time of sign entrance/exit (which is corresponded to the 12 "mid-climates" within Chinese lunisolar calendar) must be obtained with appropriate software or with the help of an ephemeris.
