It doesn't make sense as written; probably should be:
Cual (es) su (fecha) de nacimiento? = What (is) your/his/her (date) of birth?
To which the answer would be:
Nacio (with an accent on the 'o') el (a number) de (a month) de (a year), e.g.
Nacio el 3 de enero de 1906 = He/she was born on the 3rd of January, 1906
or
(Yo) naci (accent on the 'i') el (your birth-date) de (birth month) de (birth-year) = I was born on the (date) of (month), (year).
The question means "What is the date of your birthday", or "When is your birthday?". The proper answer woul be to give your birthdate.
I believe that is the phrase used to ask for someone's birthday.
"Cual es su apodo" means "What is your nickname?" in English. It is a question asking for someone's informal or alternative name.
