A Bar or Bat Mitzvah (son or daughter of the commandment), is when a Jewish child reaches maturity and is responsible for themselves under Jewish Law. This very impotant event to one who is Jewish usually occurs when they are thirteen years old. A Bar or Bat Mitzvah declares one who is Jewish to become a Jewish adult.
At the Bar or Bat Mitzvah ceremony the one who is becoming a Jewish adult reads the Torah, which is the five books of Moses. Calling the boy or girl to recite the Torah blessings is called an aliyah.
When the girl or boy has become a Bar or Bat Mitzvah, they are responsible for participating in all the mitzvot. This also includes Yom Kippur. The Jewish adult is now responsible for their sins and the parents usually thank God that they aren't responsible for their childs sins from now on.
