Clear, authoritative answers on Sidereal vs Tropical charts, Nakshatras, and Vimshottari Dasha cycles.
A Janam Kundli is an exact map of the heavens at the precise moment and geographic coordinates of your birth. Using the sidereal zodiac with the Lahiri Ayanamsha, it maps the 9 Grahas (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, Ketu) across 12 Bhavas (houses) and 27 Nakshatras (lunar mansions).
Vedic astrology uses the Sidereal zodiac, which tracks the actual visible positions of constellations in the sky, adjusted for equinoctial precession (~24° offset). Western astrology uses the Tropical zodiac, tied to Earth’s seasonal solstices and equinoxes. Cosmos Celestia computes both side-by-side from the same high-precision planetary positions.
Nakshatras are 27 lunar mansions of 13°20’ each. Your Janma Nakshatra (the Moon’s birth constellation) reveals your mental temperament, psychological tendencies, karmic disposition, and dictates the timing sequence of your Vimshottari Dasha cycles.
Vimshottari Dasha is a 120-year planetary timeline system. Divided into Mahadashas (major periods) and Antardashas (sub-periods), it acts as a celestial clock highlighting when planetary potentials in your chart awaken—such as marriage timing, career shifts, wealth accumulation, or health cycles.
