None. I can make one prediction about your future which is guaranteed, but you would not like it.. And that is that you are going to die. Nobody can make any better prediction than that.
Psychics are a joke. Just for fun, we once called the Psychic Hotline... They asked my name and birthdate... I told them they were the psychics, they should be able to tell ME that. The psychic hotline later went bankrupt... You would think they would seen that coming, huh?
In any event, if you believe in such things, a simple birthdate is not sufficient. Astrologers, in order to make an "accurate" birth chart, need your birthdate, the exact time of birth, and the latitude and longitude of where you were born.
Personally, it is easier for me to believe in a God than to believe some burning ball of gas, a million light years away, has any bearing upon my future (the only exception being if that ball of gas tossed a rock in our direction a million years ago which is about to hit us.. In which case you are back to my original prediction for your future).
