Horoscope.

The horoscope and natal chart, are prediction methods not proven based on the position of the stars at the time of birth. 

The term derives from the Greek "ὥρα" (time, "time"), and "σκοπέω" (skopeo, "examine"). 

There is no evidence or scientific studies to support the validity of the predictions obtained by any of the different versions of this practice. 

Some people argue that belief in the effectiveness of the horoscope is enhanced by a normal psychological phenomenon (based on automatic search for patterns by the brain) in people, for which the matches are easy to remember and forget the faults of coincidence. 

Many cultures used similar forms of prediction based on its own calendars in direct relation to the stars. The Mayan civilization, for example.
