Bar Mitzvah's have been around for over 2 thousand years and it's a rite of passage for 13 year old boys who have become men. What better way to celebrate than by sending out customized Bar Mitzvah Invitations. After the Bar Mitzvah the men will finally be able to have the moral responsibility to be adults and are allowed to read from the Torah. This also allows them to get married and follow the 613 laws of the Torah.
Bar Mitzvahs are almost entirely based on interpretations and customs of the synagogue or temple their parents attend. It goes without saying that they are huge parties often accompanied by elaborate gifts. New York is one of the most sought after places to have their party. They have entire halls dedicated to the ceremony and party.
In the old days, learning Hebrew and reading of the Torah was taught by the father but now, it's often taught at the synagogue. Here's an interesting fact, when a man reaches the age of 83 he can have a second Bar Mitzvah because the normal life span is only 70, so if they reach 83 it signifies their 2nd 13th birthday.
