What is Zoroastrian astrology?
Zoroastrian astrology is an ancient cosmological system from the Bundahishn that maps planetary influences across 7 generations of ancestry. Each classical planet - Sun (Hvarenah), Moon (Mah), Mercury (Tir), Venus (Anahid), Mars (Wahram), Jupiter (Ohrmazd), Saturn (Kaywan) - corresponds to a generation: yourself through your great-great-great-great-grandparents.

Why Zoroastrian Astrology Differs From Vedic and Western Traditions
Zoroastrian astrology is rooted in the Avestan tradition of ancient Persia. Where Western astrology builds an individual psychological profile from the tropical zodiac, and Vedic astrology layers karmic timing through the sidereal zodiac and the dasha system, Zoroastrian astrology centers on ancestral lineage. The seven classical planets are read not just as personality forces but as cosmic signatures of seven generations of forebears.
Vedic astrology, drawn from the Indian sage tradition, emphasizes karma, planetary periods, and remediation through ritual. Western astrology, descended from Hellenistic and modern psychological lineages, frames the chart as a map of inner archetypes. Zoroastrian astrology complements both: it treats your birth chart as inherited cosmic blueprint - a record of which ancestral patterns shaped you, and which you are free to consciously transform. All three traditions share the same seven luminaries; they differ in what they choose to read in them.
