First, let's clarify what a bar mitzvah actually is. On a Jewish boy's 13th birthday he becomes a bar mitzvah, there is no ceremony necessary for this to happen, it's automatic.
Now, when a boy becomes a bar mitzvah, one of the traditions is for him to publicly read from the Torah as this is a responsibility held by Jewish adults. However, any Jewish male who is not circumcised is not allowed to be the person who reads the Torah portion publicly. Therefore, if a Jewish boy is not circumcised, he cannot participate in the ceremony associated with becoming a bar mitzvah.
Jewish boys and men
He can have one as an adult.
A Jewish boy automatically becomes a bar mitzvah on his 13th birthday, no ceremony is required.
For babies, if they are boys, they have a Bris Milah. For girls they have a Zevad habat. In Chassidim, boys have their first haircut, which is called an Upsherin. Girls have their first Sabbath Candle lighting. When boys turn 13, they make their Bar Mitzvah. Girls have Bat Mitzvah, when they are 12.
A Jewish boy becomes a bar mitzvah when he turns 13. A Jewish girl becomes a bat mitzvah when she turns 12. Not all that surprising when you consider that "bar" is Aramaic for "son", and "bat" is Hebrew for "daughter".
Yes
It's easy: 1. Jewish boys get circumcised, Jewish girls just undergo baby naming 2. Jewish boys have BAR Mitzvahs, Jewish girls have BAT Mitzvahs 3. In Orthodox Judaism, Jewish men are in charge of the synagogue while Jewish women are in charge of the home
Jewish boys have a Bar Mitzvah at 13 years as a rite of passage.
Bar Mitzvah
Those who haven't been Bar or Bat Mitzvahed.
The Jewish ceremony when young boys join the synagogue is called a Bar Mitzvah (for boys) or a Bat Mitzvah (for girls). It is a significant milestone in Jewish tradition where the individual takes on new responsibilities and is considered an adult within the community.
You may start puberty, you will probably be in about 7th grade, you may get bar/bat mitzvahed if your a Jew.
