Core concept
Kundli
Kundli is the Vedic birth chart — a diagram of the sign, house and degree of each of the nine grahas at the exact moment and place of a person's birth. Every other reading in Vedic astrology, from Dasha timing to marriage matching, starts from it.

- Lagna
Lagna is the ascendant in Vedic astrology — the zodiac sign rising on the eastern horizon at the exact time and place of birth. It becomes the 1st house of the chart and sets the order of all twelve houses.
- Nakshatra
Nakshatra is one of the 27 lunar mansions of Vedic astrology, each spanning 13°20′ of the zodiac — a finer division than the twelve Rashis. The Moon's Nakshatra at birth sets the starting point of the Vimshottari Dasha and is read as a strong indicator of disposition.
- Rashi
Rashi is a zodiac sign in Vedic astrology — one of the twelve 30° divisions of the sidereal zodiac. "Your Rashi" usually means the sign the Moon occupied at birth, the sign a Vedic astrologer asks for first; the Sun's Rashi is closer to the Western sun sign.
- Ayanamsa
Ayanamsa is the angular offset — about 24° today — between the tropical zodiac of Western astrology and the sidereal zodiac of Vedic astrology. Kundli Saathi applies the Lahiri ayanamsa, the most widely used in India, to place every planet in its Vedic sign.
