This instalment illustrates the unique precision of Age Harmonics.
Below is the Birth Chart of a woman born in Sarajevo on 23 October 1950 at 3:00 am. It is noteworthy that the time is not “rounded off” but is accurate, timed (her mother said) by the town clock striking the hour.

An important event occurred in the life of this woman on January 7, 1971.
Before looking at the solution try to find the answer for yourself. That is many times more valuable than simply reading how it is done.
We have a precise date and a precise birth time, so let’s see what Age Harmonics can produce:
Here is the
Age Harmonic Chart of 7 Jan 1971, 3:00 am CET at the birth place, Sarajevo:

If you follow the rules for Reading Charts that I recommended in Instalment 7 you will have no difficulty in deciding what happened in the life of this woman on that day.
The most important feature of the Chart is (obviously) Jupiter conjunct the 10th Cusp.
This is enough on its own to establish Jupiter’s primacy but Jupiter is still further established by its trine to and Mutual Reception with the Sun which rules the 10th House.
So what is the verdict? A good job of course. The woman was offered and accepted a position that suited her so well she held it for 30 years.
When we look further into the Chart we see supporting factors: Moon in the 6th House (work) trine Venus in the 10th (career).
But what of the close square, Pluto square Neptune and the Moon? Is there any explanation of that?
There is, indeed, an explanation quite unrelated to the work position: Six days earlier, on 1 Jan 1971, the woman was raped by her then boy-friend, after which with a complete change of fortune she obtained the good position shown in the Age Harmonic Chart.
