Sidereal vs. Tropical Astrology
The fundamental distinction between Vedic (Jyotish) and Western astrology lies in zodiacal reference systems. While both divide the ecliptic into twelve signs, they measure from different starting points. This results in approximately 24 degrees of separation as of 2026.

The Practical Shift
Because of this ~24-degree offset (the ayanamsa), planets and the ascendant usually (but not always) shift to the previous sign when calculated sidereally. For example, if your Sun is in tropical Gemini between 0º and 23º, it will likely shift to sidereal Taurus.
This shift is caused by the precession of the equinoxes, which is a gradual westward drift of about 50 arc seconds per year. While the Tropical zodiac stays synchronized with the calendar seasons, the Sidereal zodiac remains anchored to the actual constellations and the galactic backdrop.
Bridging the Two Systems
Neither system is "more correct" than the other; they simply measure different phenomena. However, I work exclusively with the Vedic tradition, which offers nuanced predictive techniques, divisional charts, and a mythology-rich framework often unavailable in Western systems.
Having an extensive background in Western astrology allows me to help you "bridge the gap" from the chart you’ve always known to the soulful depth of your Vedic sidereal birth chart.
