Bat mitzvah, << baht MIHTS vuh, >> is a religious observance in Judaism that celebrates a girl’s entry into the adult Jewish community. The term means daughter of the commandments.
When a girl reaches physical maturity, assumed to be the age of 12, she is responsible for all the religious observances, obligations, and prohibitions of a Jewish adult. No formal religious ceremony is needed for this to happen, but many families gather with their friends to celebrate the occasion. In most cases, the girl prepares for many weeks for the bat mitzvah service because it usually includes a public demonstration of what she has learned about Judaism.
