If l had time on my hands, yeah probably.
It is very time-consuming because you have to find at least 10 people of each decan (and the dwad changes every 2.5 degrees from 0-30!!!) so for me l have aries AC.
I first figured that my decan was sagittarius (decans change every 10 degrees)
then l had to find people who had their Aries AC's at:
degrees in their charts.
Find the common theme between the individual dwads and apply it to myself. Took me weeks
you feel amazing when you figure it out though. I then had an astrologer rectify my chart and she came up with the same degree that l had so it must work.
