How Zodiac Signs Are Determined
The Science Behind Sun Sign Calculation
Your zodiac sign is determined by the position of the sun along the ecliptic—the path the sun appears to trace across the sky throughout the year—at the moment of your birth. The tropical zodiac divides this 360-degree path into twelve equal 30-degree segments, each corresponding to a zodiac sign.
This system has its roots in Babylonian astronomy from over 2,000 years ago and was refined by Greek astronomers. While the actual constellations have shifted due to Earth's axial precession, the tropical zodiac remains fixed to the seasons, with Aries beginning at the spring equinox.
The sun moves approximately 1 degree per day (0.9863°), completing its journey through all twelve signs in one solar year (365.25 days). This consistent movement allows us to calculate your sun sign with precision based on your birth date.
