The ascendant is the sign rising on the horizon at the time of birth, also known as the rising sign. Your ascendant is your persona, your public face, which may compliment, amplify, subdue or even mask your planetary frequencies, specifically your Sun & Moon.
Your ascendant also determines which houses your planets occupy on the wheel of life. Each house indicates specific life issues and those your planets occupy have heightened significance.
However, though it's illuminating information, the ascendant and houses require an exact birth time to calculate, and many people don't know theirs. And a small error can make a big difference. The good news is, it's non-essential information. Only the Planets, Aspects & Signs are essential and do not require a birth time. Only the Moon moves more than one degree a day, moving about 12 degrees daily. So when the exact or approximate birth time is unknown, noon is used, assuring that the Moon is no more than 6 degrees from
the birth position, and usually less. Not ideal, but workable.
