Sidereal vs Tropical Zodiac: Which Is More Accurate?

The sidereal and tropical zodiacs are two ways of measuring the 12 signs. The tropical zodiac (Western) is fixed to the seasons, while the sidereal zodiac (Vedic) is fixed to the actual stars.

The Core Difference

• Tropical — 0° Aries always begins at the spring equinox; signs don't move with the stars.
• Sidereal — 0° Aries begins at the actual star Spica/Aries constellation; signs track the real sky.

Because of the Earth's precession, the two have drifted about 24° apart — meaning your sidereal sign is usually one sign behind your tropical sign.

Which Is More Accurate?

Both are 'accurate' for what they aim to do. Tropical astrology is strongest for personality; sidereal astrology is strongest for precise planetary positions and timing. Lopinuze calculates both.
