Eclipse In Birth Chart Calculator

This page compares exact eclipse degrees against the core natal planets and angles using conservative major-aspect orbs. It is built for readers who want a real chart-contact layer without pretending that the chart engine already gave us a richer eclipse-analysis payload.

API required

Input

Birth chart and eclipse window

Enter exact birth data, then choose the eclipse year window you want to compare against the natal chart. The birth city is reused for the chart itself and for local eclipse time labels.

Select the exact city from the suggestions. Coordinates and timezone are stored automatically.

Eclipse timing window

Year range

The birth city controls house overlays and local time labels. The year range controls which eclipse seasons are compared against the chart.

This route uses exact eclipse degrees, exact natal placements, and conservative major aspects only. It avoids fake certainty about path visibility or provider-only impact data.

Output

Eclipse-to-natal contacts

Exact eclipse contacts to core natal planets and angles in the selected year window.

Awaiting result

Export options appear after a live result is available.

Submit exact birth data and a year window to compare the eclipse degrees against the core natal chart points.

Guide

How this calculator works

Exact eclipse-to-natal contact route built from eclipse degrees, natal houses, and conservative major-aspect overlays.

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.
