This is the important data needed to construct an accurate natal astrological chart. Although many newspapers give astrological predictions or forecasts based only on the date of birth, that is like trying to fully understand how a car works by looking at the gas cap. For an accurate chart you need three things:
- Date of birth
- Time of birth
- Location (the latitude and longitude) of birth.
If one or more of these factors is not known, but if the time, date, and location of important life events is known, some astrologers will do a very time-demanding research (known as chart rectification) to create an accurate natal horoscope.
