CALCULATE YOUR STAR-BASED (TRUE SIDEREAL) NATAL CHART
True Sidereal Astrology, also known as Star-based Astrology, is a type of astrology that takes into account the current positions of constellations in the sky. Your Star-based natal chart shows an astronomically accurate reflection of the solar system the moment you were born. This compares to mainstream Astrology in that mainstream Astrology doesn't refer to the actual, current positions of the stars and constellations when calculating natal charts. Instead, it derives its basis from the Tropical Zodiac which is fixed to the seasons.
How does this affect your chart? Some of your signs will change with this system! Mainstream Astrology may categorize your Sun sign as a "Gemini" or "Scorpio", but in actuality, the Sun could have actually been in alignment with a different constellation.
