Bar Mitzvah

A Bar or Bat Mitzvah is a monumental milestone in a Jewish
person’s life. It is a time of excitement, anticipation, and
sometimes fear and apprehension. Most children are energized
for the party that is being planned on their behalf.
A boy is Bar Mitzvah when he reaches his thirteenth birthday,
while girls are Bat Mitzvah when they are twelve, corresponding
to her earlier maturation.
Historically, Bar/Bat Mitzvah is the ceremonial occasion that marks
the time when a young person is recognized as an adult in the
Jewish community and is responsible for performing mitzvot. For
example before children have their Bar/Bat Mitzvah, they do not
need to fast on Yom Kippur. However after Bar/Bat Mitzvah, they
are required to fulfill this mitzvah.
For a boy, among his many new responsibilities, beginning from his Bar Mitzvah day and onward, he wraps Tefillin every day of the week besides Shabbat and certain holidays. They are also counted in the minyan, a quorum of ten required to conduct a
service.
