Calculate your chart
Enter accurate birth details.
Birth time and place are needed for houses. Pattern geometry uses the ten planets and does not count the Ascendant as a planet.
Birth chart geometryFree · no account
Find the larger patterns inside your birth chart.
Enter your birth details to check whether separate planetary aspects join into a complete geometric structure. Every match shows the exact planets, required connections, orb evidence, life areas, and a practical way to work with the pattern.

The scan checks Grand Trine, T-Square, Grand Cross, Yod, Kite, Mystic Rectangle, and sign-based Stellium using explicit geometry rules.
Before you startInputs, calculation, limits, and saving+
What to enter
Required: Enter birth date, exact time, and birth place.
Optional: Use the default aspect and orb settings unless you already understand the alternatives.
Example input — not your result: Example: January 1, 1990 · 12:00 · Shanghai, China.
Unknown birth time: Without an exact time, angle- and house-based patterns should not be treated as reliable.
What you get
Detect multi-planet geometry and understand what each structure connects. The result includes pattern scan, orb evidence, plain explanation.
How it is calculated
Scans calculated planet longitudes for supported multi-planet geometries within the selected orb rules.
Data time: The result records its calculation time. Date-based tools use the selected date; location-based tools also show the resolved local time zone.
Result limits
The chart positions are calculated; the written astrology meaning is a reflective convention, not a diagnosis, certainty, or promise of events.
Missing result
A missing aspect or pattern usually means nothing met the selected geometry and orb rules. Missing houses or angles usually point to uncertain birth time or unresolved place data.
How to fix an error: Check the date format, then enter a specific City, Country suggestion. If the time is unknown, follow the tool's unknown-time instruction instead of inventing a time.
Next step and saving
Do next: Open the tightest detected pattern and check which life areas its planets actually connect.

HELP
Questions people ask before they start
Short answers about inputs, limits, and how to read the result.
Why did the tool find no pattern?
Many charts do not contain one of these seven complete structures under a given orb profile. That does not make the chart weak or uninteresting; individual aspects and placements still matter.
Can changing the orb setting change the result?
Yes. Tight orbs require aspects to be closer to exact, while wide orbs admit more connections. The result always displays the exact limits used so you can judge the evidence.
What definition of stellium is used?
This first version uses three or more of the ten planets in one zodiac sign. It labels this explicitly and does not require all members to be conjunct.
Does birth time matter?
It matters greatly for houses and can matter for the Moon. This analyzer excludes angles from the planetary pattern itself, but an uncertain time still makes the life-area layer less reliable.
