What does it mean word for word?

The phrase literally translates to "when is your birthday".

Which one should you use?

In Spanish, you use cuándo (when) instead of qué (what) to ask this question.

Is it said differently in some regions?

In certain regions, such as Spain and parts of Latin America, it is common to shorten cumpleaños to cumple in the informal expression ¿Cuándo es tu cumple?

To adjust the level of politeness, you can change the possessive adjective: use tu for informal situations and su for formal or polite situations.
