Determining deadlines to a certain outcome

1
How can an exact or close estimate to an outcome be decided in a horary chart? How could I determine the ammount of days or months to a given situation pertaining to a question, or scenario?

I hope I worded that properly, you guys tell me if ya'll don't understand the question. I am pretty tired, can't sleep though. So sorry if what I type is misunderstood or anything like that. :)
