I would say that it's a lot like planets, when the angles are contacted in a hard or significant way there are major changes having to do with what the angles houses signs and planets are doing that are involved!
My aunt has a lot on the 29th degree including AC but I don't know what's completely in her personal life. Something that stood out to me is she broke a cycle of batshit crazy and cruel moms in our family, it was a ripple effect and that time is over. Her moon 29 degrees taurus and jupiter in opposition at 29 degrees scorpio.
She got in a divorce once, 29 degrees taurus. Thing wound up for the better, jupiter opposition? 29 degrees moon taurus conjunct saturn in Gemini, finished a degree but couldn't do anything with it. Unfinished education in high school set her back from doing what she wanted, started and stopped a lot of different things with education. She did get to where she wanted though after some obstacles and doing different things. that could be gemini. hm. it all ties together! but yeah.
Emphasis on this being just my guess of these events and details being related to 29th degree!
I haven't studied it much, I just now looked because I saw this and thought hey why not.
I read that when things are at a significant degree and it's contacted event's are set off or certain life events indicated.
