A
horoscope (or other commonly used names for the horoscope in English include natal
chart, astrological chart, astro-chart, celestial map, sky-map, star-
chart, cosmogram, vitasphere, radical chart, radix, chart wheel or simply chart) is
an astrological chart or diagram representing the positions of
the Sun, Moon, planets, astrological aspects and sensitive angles at the time of an event, such
as the moment of a person's birth. The word horoscope is derived from
the Greek words ōra and scopos meaning "time" and "observer" (horoskopos, pl. horoskopoi, or
"marker(s) of the hour"). It is used as a method of divination regarding events relating to the point
in time it represents, and it forms the basis of the horoscopic traditions of astrology.
In common usage, horoscope often refers to an astrologer's interpretation, usually based on a
system of solar Sun sign astrology; based strictly on the position of the Sun at the time of birth, or
on the calendar significance of an event, as in Chinese astrology. In particular, many
newspapers and magazines carry predictive columns, written in prose that may be written more
for increasing readership than tied directly to the Sun or other aspects of the solar system,
allegedly based on celestial influences in relation to the zodiacal placement of the Sun on the
month of birth, cusp (2 days before or after any particular sign, an overlap), or decant (the month
divided into 3 ten-day periods) of the person's month of birth, identifying the individual's Sun
sign or "star sign" based on the tropical zodiac.[1]
In Hindu astrology, birth charts are called kuṇḍali which are very significant and are based on
movement of stars and moon. Auspicious events and rituals are started after checking
the kuṇḍali of a person including the marriage in which the birth charts of the boy and girl are
matched.
There are no scientific studies that have shown support for the accuracy of horoscopes, and the
methods used to make interpretations are pseudo-scientific.[2][3][4][5][6]:1350 In modern scientific
framework no known interaction exists that could be responsible for the transmission of the
alleged influence between a person and the position of stars in the sky at the moment of birth.[7]

In all tests completed, keeping strict methods to include a control group and proper blinding
between experimenters and subjects, horoscopes have shown no effect beyond pure chance.[9]

Furthermore, some psychological tests have shown that it is possible to construct personality
descriptions and foretelling generic enough to satisfy most members of a large audience
simultaneously, referred to as the Forer or Barnum effect.
