Sidereal vs tropical astrology — what is the difference?
Sidereal astrology measures planets against the actual constellations in the sky, while tropical astrology measures them against the seasons (anchored to the spring equinox). Over centuries the two have drifted about 24 degrees apart, so your sidereal sign is often one sign earlier than your tropical one. Vedic astrology uses the sidereal system — it reads the sky as it physically is right now.
Why the two disagree
Tropical fixes the zodiac to the seasons; sidereal fixes it to the stars. Because the Earth slowly wobbles, the seasons and the constellations no longer line up, leaving a gap of roughly 24 degrees. That gap is why your sign can differ between systems.
Which one Levite uses
Levite is sidereal. It computes your chart against the real positions of the stars, which is the basis of the Vedic timing system and its planetary periods.
Questions people ask
- Why is my sidereal sign different from my usual sign?
- Most popular horoscopes are tropical. Because the systems have drifted about 24 degrees apart, your sidereal Sun is often the previous sign.
- Which system is correct?
- Both are internally consistent; they answer different questions. Sidereal tracks the sky as it physically is, which is what Vedic timing is built on.
