Reddit mentions of Primary Directions: Astrology's Old Master Technique

Transits don't really determine or indicate these types of things. You need more advanced timing techniques like profections, solar returns, and primary directions to get a good grasp of when certain events will occur in the life of a native.

I reccomend Martin Ganstens book on primary directions.

It will walk you through all you need to know to practice in a simple way using clock time and in the back you have the formulas to do it by hand.

If you want to learn about them in depth you should take his course.
