Birth Chart Calculator
Simplified Sun-sign-only birth chart. A full birth chart needs exact birth time and location. For entertainment purposes only.
The Sun Sign Is Only the Starting Point
What most people call their "sign" is really just the Sun sign — one piece of a full astrological birth chart, determined purely by the calendar date the Sun occupies a given zodiac constellation. This calculator identifies that Sun sign, its element, and its traditionally associated traits from a birthdate alone.
The Formula
Element = element of Sun Sign (Fire, Earth, Air, or Water)
Sun sign date ranges follow the standard tropical zodiac boundaries used in Western astrology, where each of the twelve signs corresponds to a roughly month-long window.
