Getting a job?

Well, My family has many money issues. So I've decided to get a job. (Or attempt to get a job) But the thing that pisses me off is the fact that I'm not sure about my birth time. I there any way to find out if I will get a job without an accurate ascendant? The two links below are the birth times that my parents told me. The cancer ascendant is the one they said I had at first. Then they suddenly agreed on the leo one. Thanks, by the way I'm 16.
