Bookish, if you want to use planetarium software to try to tell the future that's totally up to you. If it make you happy, go for it!
For Windows Cartes du Ciel is a good free one. These programs are very accurate.
But as Bert points out and afaik astrology is still using a 2000 year old star map that is about a month out when superimposed on solar system objects. Makes no sense to me whatsoever - using present day positions for planets, Moon and the Sun but 2000 year old positions for stars. You'd think at least one should try to be consistent, i.e. use 2000 yo planets, moon + sun with 2000 yo stars, or present day planets, moon + sun with present day stars, but astrology does not work that way. (it does not work at all afaic but that's another issue)
