"Cual es la fecha de hoy" means "What day is it?" "Cual" is the question word. Although "que" literally means "what," "cual" is more often used as "what" for questions. "Fecha" means "date," as in the date of the month (not a date to the movies). Finally, "hoy" means "today." To answer this, you will provide the number and month of the day: "Es el 24 de marzo." This translates to: "It's March 24th."
