One engine · Many traditions
Astronomy is universal. The systems aren't.
The same sky sits under every tradition. What differs is the mathematics each culture built on top of it. AstralMath computes each by its own authentic rules — never a Westernized approximation.
Vedic (Jyotish)
liveThe 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
Western (Hellenistic → Modern)
liveThe tropical system most of the world knows: sun/moon/rising, aspects, and transits, traced from its Hellenistic roots to the modern chart.
Tropical · Tropical zodiac, Placidus/whole-sign houses, aspects
Chinese (BaZi / 四柱)
buildingThe Four Pillars of Destiny, derived from the true solar terms — not the pop "zodiac animal," but the calendar mathematics underneath it.
Solar-lunar · Four Pillars, ten heavenly stems, twelve earthly branches
Mayan (Tzolkin)
plannedThe 260-day sacred count and Long Count, computed from the GMT correlation constant — a calendar system of remarkable astronomical precision.
Ritual count · 260-day Tzolkin, Long Count correlation
Arabic / Perso-Islamic
plannedThe medieval Arabic tradition that carried Hellenistic astrology forward: the 28 lunar mansions and the calculated lots (Part of Fortune and beyond).
Tropical + lots · Lunar mansions (manazil), Arabic parts / lots
