Vedic vs Western astrology: what's the difference?
How is Vedic astrology different from Western astrology?
Vedic astrology (Jyotish) uses the sidereal zodiac — anchored to the fixed stars and constellations. Western astrology uses the tropical zodiac — anchored to the seasons (the equinoxes). Because of precession, the two zodiacs have drifted apart by about 23–24 degrees. That means your Vedic Moon sign, Lagna (rising sign), or Sun sign can be one sign earlier than your Western chart shows.
Which zodiac is "correct"?
Neither is a mistake — they are different reference frames. Jyotish tradition works in sidereal coordinates; most Western schools work in tropical coordinates. What matters for a reading is consistency: compute the whole chart in one system and interpret from that map. Naksha uses Lahiri ayanamsa, whole-sign houses, and classical Parashari techniques on the sidereal chart.
What is Lahiri ayanamsa?
Ayanamsa is the angular difference between tropical and sidereal longitudes. Lahiri ayanamsa is the standard used in Indian government ephemerides and in most modern Vedic software, including Naksha's Swiss Ephemeris backend. Without ayanamsa correction, you are not computing a standard Vedic chart.
Do Vedic astrologers use the same houses as Western?
Many Vedic practitioners use whole-sign houses (each sign is one house from the Lagna). Western astrologers often use quadrant systems (Placidus, etc.). House boundaries can shift conclusions about which planet rules career or marriage, even when planet signs match.
Can I use both charts?
Yes — many people keep a Western natal chart for psychological language and a Vedic chart for dasha timing and classical techniques. Compare them as two maps of the same sky, not as competing truths. For chart-grounded conversation in Naksha, we read the sidereal map only.
