How this calculator works
Search actual major-aspect crossings for a selected transit body and natal target. View computed factors without outcome or intensity scores.
Who it is for
Required input
Method note
- The natal chart establishes one fixed tropical longitude. Unknown legacy settings require recalculation.
- A bounded continuous-angle search resolves directed major-aspect crossings, including station splits and repeated hits.
- Each event exposes UTC, direction, angular residual and final bracket. Incomplete searches return an error, never a best window.

What the result means
These are measured angular contacts for the selected body pair. Their interpretation does not measure success, stress, wellbeing or wealth.
Example result
Verified synthetic daily example
For synthetic birth details 14 July 1990, 14:30 EDT, New York, the tropical Sun target is 112.051 degrees. Searching 14 July 2026 finds a direct Sun conjunction at 07:20 EDT (11:20 UTC). Independent Swiss verification differs by 0.014 arcseconds and 0.42 seconds in this one case.
Enter those synthetic birth details, choose Sun to natal Sun, 14 July 2026 and America/New_York to reproduce this example. Other body pairs require their own verification.

FAQ
Common Questions
Does this cover every transit?
It searches the five major aspects for one selected transit body and natal target. Other pairs are outside its coverage.
Why is the forecast timezone needed?
It defines local midnight boundaries and display times. Geocentric transit longitudes do not depend on a forecast city's coordinates.
Does a contact predict an outcome?
No. The result records an angular event; it contains no intensity, success or category score.
