Zodiac used
A Kundali uses the sidereal zodiac (fixed to actual star positions); a Western birth chart typically uses the tropical zodiac (fixed to the seasons). The two are currently about 24° apart.
Kundali, in Western terms
'Birth chart' and 'Kundali' describe the same underlying idea: a map of where the planets were at your exact moment of birth. The difference is mostly in method and vocabulary.
Vedic vs Western
A Kundali uses the sidereal zodiac (fixed to actual star positions); a Western birth chart typically uses the tropical zodiac (fixed to the seasons). The two are currently about 24° apart.
Kundali readings lean heavily on the Moon sign (Rashi), Nakshatra and Dasha timing. Western charts lean more on the Sun sign and aspect patterns.
Both use the same twelve houses, the same core planets, and the same basic idea — a personalised map based on your exact birth details.
