dec 20th freeing the soul question

[Big Dipper]

Would that date be a good one to start a freeing the soul working? I was thinking of the 18th since that's when the moon enters scorpio, but it says "freeing the soul" 2 days later. Is that because of saturn or something? I plan on doing another 40 day working. I don't know what I need freed from though. I have some bad stars conjunct my ruler, maybe I should do it for that?

It may be better to wait until the 20th.
