How we calculate
The calculation runs on the same engine as astroway.info. The text follows a table of facts about your couple, and every number in the PDF is checked against it.
Ephemeris
Planet positions come from the AstroWay api, built on Swiss Ephemeris. Before launch we checked synastry, composite, Davison and ashta-kuta against an independent Swiss Ephemeris calculation on a set of couples, including ones without a birth time and above the polar circle.
Two zodiacs
The Western chapters use the tropical zodiac. Ashta-kuta uses the sidereal zodiac with the Lahiri ayanamsha, so the Moon there may be in a different sign than in synastry.
The table of facts
For each order we calculate all systems once and fix the result in a table of facts. The book’s text follows it, and before sending, code checks every aspect, degree, guna and channel in the PDF against that table.
No percentage
Sites that give a couple one number mix systems that measure different things. We show each one separately: you can see for yourself where they agree.
Data
Your partner’s data is only needed for the calculation and is deleted after the book is generated. We do not create a profile for them or write to them.
