Guide

How this calculator works

Provider-backed one-city match tool that compares a selected city against exact astrocartography line geometry.

Who it is for

Best for readers who want exact natal chart math, verified placements, and a clear line between real calculation and lightweight editorial tools.

Required input

Exact birth date, exact birth time, birth city, time zone context, and a supported house system.

Accuracy note

This calculator requires exact planetary positions and should use the astrology calculation API for accurate results.
  • The browser submits the form to a server-side function instead of calling AstroWay directly.
  • AstroWay returns the exact planetary, house, and aspect data.
  • The result page can then be reused by later calculators without pretending the frontend did the math itself.

Guide

What the result means

This route is the exact-data backbone for the rest of the product. It matters because it gives users a trustworthy path into birth-chart-level accuracy before any interpretive layer is applied.

Example result

Natal chart example

A typical output returns the planet list, house cusps, aspects, and metadata required for downstream chart interpretation.

Use the exact chart to verify Moon sign, Rising sign, house structure, and any advanced chart calculators that should never be guessed from date-only logic.

Guide

What this result helps you understand

These tools use precise chart calculations for high-accuracy results.

Exact chart calculators depend on accurate birth data. If the time or location is wrong, the resulting Rising sign, houses, and some aspect patterns can shift materially.

FAQ

Common Questions

Why is this page separate from lighter calculators?

Because exact chart math should be clearly separated from simpler rule-based tools so users know when precision really matters.

Can I skip the birth time?

Not if you want reliable houses, Rising sign, and time-sensitive chart interpretation.

Why keep the API call on the server?

To protect secrets, normalize errors, and keep the product's exact-chart path trustworthy.
