A cesarean birth is said to strain the ancestral connection (it can be restored).

Birth order

A firstborn's chart ties more strongly to both parents.

If a parent has passed

A birth date within 5 days of a parent's death date marks a strong inherited connection. This feeds the Eight Keys check in your reading.

FAQ

Horospire is an ancestral horoscope platform inspired by ancient Zoroastrian cosmology (the Bundahishn and Avestan Fravashi tradition) and modern epigenetic science. It maps your birth chart across 7 ancestral generations using the classical planetary order - Sun through Saturn - to reveal inherited traits, ancestral patterns, and your unique cosmic blueprint.
Only your birth date (day, month, year) and gender are required. Everything else is optional and deepens the reading: your exact birth time (sharpens the Moon sign and all time-sensitive calculations), your birth place (unlocks your Ascendant and the 12 houses), your parents' birth dates, parents' death dates and grandparents' birth and death dates, your birth method, and whether you are the firstborn. Even with just a birth date you receive a comprehensive ancestral analysis.
The 7 generations follow the ancient planetary order: 1st Sun/Hvarenah (Yourself), 2nd Moon/Mah (Parents), 3rd Mercury/Tir (Grandparents), 4th Venus/Anahid (Great-grandparents), 5th Mars/Wahram (Great-great-grandparents), 6th Jupiter/Ohrmazd (3x-great-grandparents), 7th Saturn/Kaywan (4x-great-grandparents). Each planetary position reveals traits inherited from that ancestral generation.
All planetary positions are calculated using precise astronomical ephemeris data. Core results - zodiac signs, Lilith/Selena positions, totem animals, blessings, hexagrams, cosmic energy windows - are computed by proprietary algorithms based on historical astrological sources, not generated by AI. Advanced models are only used as a second step to further interpret the already-calculated output. Horospire is designed for self-reflection and entertainment, not scientific prediction.
