A bat mitzvah is a Jewish coming-of-age ceremony for girls, typically held when they turn 12 years old. This event marks the transition from childhood to adulthood in the Jewish community, signifying that the girl is now responsible for her own actions and can participate in religious practices. During the ceremony, the girl often reads from the Torah, which is the central reference of the religious Judaic tradition. The celebration usually includes a party with family and friends, where the girl may receive gifts and enjoy various festivities, symbolizing her new role within the community.
