The Astrological Aspects
Aspects are the angles your planets form to one another in the birth chart — they show how two forces within you interact: flowing in harmony, driving through tension, or finely adjusting. Aspects are what turn separate planets into a living inner fabric. Birth Codex calculates your aspects precisely from your birth date, place and time — embedded in 23 cosmic systems.

What the aspects show
The angle matters — Each aspect is a specific angle — 0°, 60°, 90°, 120°, 180° and more. The angle determines whether two planets support, rub against, or must sensitively find each other.
Harmony and tension — Harmonious aspects (trine, sextile) grant talents; challenging ones (square, opposition) are the engines of your growth. Both belong to a mature chart.

Frequently Asked Questions
What is an aspect in astrology?✦
An aspect is an angular relationship between two planets in the birth chart. The angle (such as 0°, 90° or 120°) describes how the two planetary forces interact — from merging through harmonious to tense.
Which aspects are good, which are bad?✦
No aspect is purely good or bad. Harmonious aspects flow easily but can make you complacent; challenging aspects create friction yet drive you to grow. What matters is how consciously you work with them.
How are aspects calculated?✦
The exact planetary positions in your birth chart give the angles between them. Birth Codex uses the Swiss Ephemeris for astronomically precise values — as part of 23 cosmic systems.
