Judaism
Bat Mitzvah (for girls) a 'coming of age' ceremony when a girl turns 12 (13 for some Jews). Bat Mitzvah means "daughter of the mitvah" or "daughter of the commandments" in Hebrew. Once a girl turns 12 (or 13), she is considered a woman and is expected to follow Jewish law. A ceremony is not required. Bat Mitzvah not only refers to the ceremony, but also to the girl herself.
