i pulled this from the internet. Since our Guru Sri Yukteswar used the idea of the conception chart, I am still very interested in this method and how it can be ascertained other than intuitively.
Sorry I can't help you steve, I used to have an interest into astrology many many years ago, when there were no softwares and the hand calcuations took a lot of time, I remember Conception astrology was discussed and some people discarded the idea, retorting that the time of Birth was the one where the individual became really exposed to the astral influence. Maybe the reasoning was a way to go around the almost insormountable difficulties you are hinting at.
Hermes trismegistus is known as a medieval alchemist and the Arabs philosophers and alchemists are from the middle ages s well (dark ages) but probably the idea is an elaboration from the knowledge of higher lost civilizations.
I don't know if today it' s possible to reach an accurate estimate of the time of Conception, I'll ask my Brother in law who is a gynecologist and made thousands of ecographies to pregnant women, I'll get back on this ASAP
