>>However, I haven’t heard a remotely plausible explanation for the position of celestial objects at the moment of birth having an impact on personality traits.

Well, to be fair Astrology is where IT started and highest Mathematics were involved in Babylonia(my username here is just a mere coincidence). Observable celestial movements here can be regarded as a natural computer of Solar system scale. How that natural computer is used is a different matter.

I'm not really into Astrology(which is mother of Astronomy, btw), but I had interest about this topic... anyway, you must wonder how different is this approach of predicting things in Universe compared to modern AI, that makes predictions from assembled data. If the modern science is regarding a question if mere existence of this world can be compared to hologram, how it is different from observing some parts of hologram to make predictions about smaller parts of it, where humans are living on Earth, that is part of observable Solar system, where other Solar objects affects it and differently on each point of surface? Besides, this looks like a more reliable mechanism in predicting future(at least for agricultural events), than looking into coffee mug after drinking a coffee or throwing bones...

PS. Despite common misconception, both Western and Chinese astrology take high value on hour of birth - not year. Western astrology can't plot precise charts without knowing time of birth and secret(primary) animal sign of a person in Chinese astrology is based on hour as well.
