I have read a lot of information saying that 6,8,12th house moon placements are extremely difficult to have but I’m curious to know more depth on it. Which signs in those houses could make it harder? And also aspects? How does having a day chart vs a night chart change its expression?

If you don’t know someone’s birth time, how do you work out their ascendant/rising? since it’s such an important placement it’s important not to get wrong.

Isn't it all based on Earth's position when you are actually on it?

Would their 3rd house be a bit more prominent compared to others? Possibly filled with benefics and somehow having an aspect or exchange with their 10th house/house lord or MC?

It’s so simple to become an influencer these days, as really anyone can do it, and so I’ve started to wonder if a lot of these people have pretty common planetary conjuncts and/or aspects.

Maybe mercury conjunct their 10th lord and placed in the 3rd house could be one?

like in whole sign my north node, and a few other planets shift a house but in like Koch and placidus they're in the another one. which one do I consider to be correct im confused
