In the case of multiple given names, the child will celebrate only one, usually the first. Traditionally, parents fix the name day of their child at christening, according to their favourite saint in case of different ones (on different days) with the same name that child will carry it throughout life. These name days are determined according to the sanctorale, a cycle found in the General Roman Calendar, which assigns to a day a saint (or as to the great majority of days, several saints), so that different names often are celebrated on that day. In Italy, one portion in person's name may be determined by the name day ( onomastico). Moreover, the low number, and the steady decline of importance and variety, of Roman praenomina starkly contrast with the current number of Italian given names. Female naming traditions, and name-changing rules after adoption, for both sexes likewise differ between Roman antiquity and modern Italian use. The Italian nome is not analogous to the ancient Roman nomen the Italian nome is the given name (distinct between siblings), while the Roman nomen is the gentile name (inherited, thus shared by all in a gens). Italian names, with their fixed nome + cognome structure, have little to do with the ancient Roman naming conventions, which used a tripartite system of given name + gentile name + hereditary or personal name (or names). (In official documents, the Western surname may be written before the given name or names.) A name in the Italian language consists of a given name ( Italian: nome), and a surname ( cognome) in most contexts, the given name is written before the surname.
