Thank you very much for your answers and explanations. Yes there is more to Astrology as only calcuzlations as you mentioned. I use JH software. There is also the BV Raman Ayanamsa which gives the same planetary positions as the Citra Paksa Ayanamsa except Venus moves in the next house.
So the whole Ayanamsa and planetary orbits calculations is an complicated thing as it seems and one cant really fix it 100% percent as it seems?
