Gemini?Taurus?

If a person is born on 21st of May,what will that person be? A gemini or a Taurus? Also please let me know if someone knows a good site where you can check person's personality traits based on birth dates especially if the person is born on a cusp.Thanks in advance..:-)

My ex girlfriend was a born on this cusp. I'm a Gemini male. It was a really wonderful relationship. In my experience the Gemini man will get the better half of the deal in this relationship. Information on cusps is pretty rare. Good luck.
