Vedic (Jyotish)
The sidereal Indian system: 27 nakshatras, dasha timing, divisional charts and Guna Milan. Our deepest tradition today — the engine began here.
Sidereal · Lahiri ayanamsa, nakshatras, Vimshottari dasha
How the math differs
The Vedic system is sidereal: it measures longitudes against the fixed stars, not the moving equinox. To get there it subtracts an ayanamsa — the accumulated gap between the tropical and sidereal zodiacs, currently about 24° under the Lahiri (Chitrapaksha) definition AstralMath uses.
The ecliptic is then divided two ways at once: into 12 signs of 30°, and into 27 nakshatras of 13°20′ each, subdivided into four padas. The Moon’s nakshatra at birth seeds the entire timing system.
Timing runs on Vimshottari dasha — a 120-year cycle of planetary periods proportioned to the Moon’s exact position within its nakshatra, so the arithmetic is fixed by the ephemeris, not chosen.
