Astrology is the study of influence or correlation between the astronomical positions of the Sun, Moon, Planets, Stars and events happening in human lives. Astrologers believe that at the time of a person’s birth, the position of the Sun, Moon, Stars and Planets have a direct influence on that person’s personality, his / her economic fortunes, relationships and many other things. For example, based on the 12 constellations of the zodiac, there is an astrology called sun sign horoscope (birth chart / natal chart) which just requires a person’s birth date that tells the general things about to happen in a person’s life. Apart from the sun sign a person may have Moon sign, Mercury sign, Venus sign, Mars sign and so on. As a predictive science, astrology facilitates the astrologers to study deep about a person’s traits and give a much suitable and positive prediction.
