Primary Directions Tests and Comparisons – tropical and sidereal.
Updated 22nd March 2023. In preparation of the release of a new AC module Primary Directions, available AC ver 2.8x. Please note that all AC views, procedures, modules are subject to change without notice. But every effort will be made to bring PD’s to AC asap as described here.
Please note that this module will probably come in two or more parts, eg part one would consider only aspects of promissors to significators only. Part two would include promissors to aspects of significators. And it maybe AC ver 3.xx.
AC will have PD directions through the bounds, aka Egyptian terms, and directions to the Desc and IC. Currently not shown in any AC screenshot.
Here’s an excellent introduction to Primary Directions.

This post shows AC’s primary direction calculations in comparison with :
-
Valens (Mac)
-
Morinus (Windows)
-
Astro.com (internet)
-
Astro Gold ver 9 (Windows)
Note Valens and Morinus invariably agree in their results as Valens is a slimmed-down version of Morinus.
Example Chart: King Charles III, aka Prince Charles: Tropical. Placidus cusps
Note that all King Charles III charts have their lat and long adjusted to match the Astro.com chart so that comparisons are geographically valid.
