Based on my birth chart, is it possible to find out the sun sign of my biological father?
Hello! Does your father happen to have a birth certificate on him? If so, then just go to or call (depending on your residential closeness) and kindly ask if he could share his date, time, hour and location of birth to you
Now that is just assuming if your father is in your life. If your father is not in the picture then I would suggest asking a relative, mainly your mother for that information. If that doesn’t pan out so pleasantly then there is always ancestry.com
