Aurapure

Synastry

Compare two natal charts with Moshier ephemeris and read the aspects between both people's planets.

Quick answer

Aurapure's synastry compares two natal charts computed with Moshier ephemeris and measures the aspects between one person's planets and the other's (conjunctions, trines, sextiles, squares, oppositions, quincunxes), using the same orbs as the natal chart. Enter both birth dates, times, and places: calculation and the aspect tally are free.

Frequently asked questions

What is synastry?
It's the comparison of two natal charts: the aspects one person's planets make to the other's are measured to read a relationship's dynamics.
Do both birth times matter?
It helps a lot: without a time the Moon and Ascendant are approximate (we use local noon). Aspects between slower planets stay reliable even without a time.
How do you read compatibility?
We tally harmonious aspects (trine, sextile) and challenging ones (square, opposition). The balance is a number, not a verdict: no couple reduces to a score.
Is it free?
Yes for the calculation and aspect tally. In-depth interpretive readings are in progress.
