A cusp, in physiology, is a point where two things touch, intersect, or fit together — one against the other. In astrology the point of the “cusp” is more abstract referring to the place in the continuum of the Zodiac or in a paper chart where a change occurs between one sign and the next or one house and the next. 

  What does it mean to be ” Born on the Cusp?”

Being “born on the cusp” to most people means a birthday (usually their own) that falls on the 21st of a month, This is approximately the day the sun changes from one sign to another in the Zodiac, Sometimes the date is the 19th and sometimes it’s the 23rd. People don’t understand the discrepancies and may wonder for years which sign they actually are.

People born “on the cusp” of a point where the Sun changes from one sign to another in the Zodiac will show this “blending of qualities” between one sign and the next directly in their personalities and often in ways that can look and feel fairly schizophrenic. Quite literally, these complex souls will not be categorically one sign or the other, but a blending of both signs involved.
