As an astrologer I need the birth time to be precise, because the most important events in person's life are indicated by aspects to the axes, i.e. ASC and MC, which depend on the birth time and birth date. Aspects to other factors, which only depend
on the date, are less importent. Example: Transit Pluto conjunction radix ASC indicates a more important event than transit Pluto conjunction radix Sun or Moon. If the birth time is wrong, my astrological prognosis will also be wrong - by days, weeks or months
- or even years.
Apart from that, we human beings tend to distort information, when we pass it on to others.
- The midwife wrote the birth time in the birth certificate one day after the birth took place. The delay was caused because
she was very busy that day, and since she delivered more than one child that particular day, there is a risk of writing the wrong birth time in the birth certificate. Furthermore, after one day, she may not remember the exact time very well. Also we all know
that some hospital staff members are very meticulous, while other are more sloppy.
- An astrologer looked up the birth time many years later and wrote it down for his/her own use.
- After some time the birth time was passed it on to a public
database like AstroDataBank.
Each time an information is passed on, an error may happen, simply because it is human to error, and all information tend to be distorted somewhat, when it is passed on from one person to another.
