What Is a Bar Mitzvah? Traditions, Etiquette and What to Wear

A bar mitzvah is an important milestone in a Jewish boy’s life. At the age of 13, he becomes responsible for observing Jewish commandments according to Jewish law.

The term is also commonly used for the synagogue service and celebration held to mark the occasion. However, the ceremony itself does not make the boy bar mitzvah. He reaches that status when he turns 13 according to the Hebrew calendar, whether or not a formal celebration takes place.

Customs differ between Jewish communities, synagogues and families. Some boys read from the Torah, some lead prayers and others give a speech or take part in the service in another way.

This guide explains what happens at a bar mitzvah, what the boy and his guests should wear, suitable gifts and important etiquette.

What Does Bar Mitzvah Mean?

“Bar mitzvah” is an Aramaic phrase commonly translated as “son of the commandment”.

It refers to a Jewish boy who has reached the age at which he becomes personally responsible for observing Jewish religious laws and traditions.

The occasion often recognises:

• The boy’s Jewish identity
• His growing religious responsibility
• His study and preparation
• His connection to his family and community
• The passing of traditions between generations

Becoming bar mitzvah does not make a boy a legal adult under UK law. It refers specifically to his responsibilities within Judaism.

At What Age Does a Boy Become Bar Mitzvah?

A Jewish boy becomes bar mitzvah at 13 according to the Hebrew calendar.

Preparation may begin months or years earlier. The boy might study Hebrew, prayers, his weekly Torah portion and Jewish traditions with a rabbi, teacher or tutor.

The synagogue service does not always take place on his exact birthday. It may be arranged for the first suitable Torah-reading day afterwards or another date agreed with the synagogue.

A celebration may also take place later due to family circumstances, travel, health or scheduling. The boy still becomes bar mitzvah when he reaches 13.

What Happens at a Bar Mitzvah?

There is no single ceremony followed by every Jewish community.

A bar mitzvah often takes place during a regular synagogue service. Depending on the congregation and the boy’s preparation, he may:

• Be called to the Torah
• Recite blessings
• Read or chant from the Torah
• Read from the Prophets
• Lead part of the prayers
• Give a speech or dvar Torah

A dvar Torah is a short talk about the weekly Torah portion, Jewish values or the meaning of the occasion.

Not every boy reads directly from the Torah. His level of participation depends on his abilities, preparation and synagogue customs.

Family members may also receive honours, give readings or deliver speeches.

The service is often followed by a reception, meal or party. This may include food, music, dancing, photographs, games and speeches.

When Is a Bar Mitzvah Celebrated?

Many bar mitzvah celebrations take place during a Saturday morning synagogue service because the Torah is read publicly on Shabbat.

However, the Torah is also read during certain weekday and festival services. The family should arrange the religious date with its rabbi or synagogue.

The party does not have to take place at the same time as the service. Some families hold a synagogue lunch followed by a larger evening celebration or a party on another day.

What Is the Difference Between a Bar and Bat Mitzvah?

A bar mitzvah refers to a Jewish boy reaching the age of religious responsibility. A bat mitzvah refers to a Jewish girl reaching this stage.

Boys traditionally become bar mitzvah at 13. Girls may become bat mitzvah at 12 or 13, depending on the community.

The way the occasion is celebrated also differs between congregations. In some communities, girls participate in the synagogue service in much the same way as boys. Other communities mark the occasion through study, speeches, meals or different religious activities.

What Does the Bar Mitzvah Boy Wear?

The boy’s outfit should be smart, comfortable and appropriate for the synagogue.

A suit is a popular choice, although it is not a religious requirement. Some boys wear a blazer, waistcoat or smart shirt and trousers instead.

Before choosing an outfit, check the synagogue’s dress code and consider:

• The formality of the service
• The season
• The venue
• The length of the day
• The boy’s comfort
• Whether the outfit can be worn again

Choosing a bar mitzvah suit

Navy, charcoal, grey and black are reliable colours for formal synagogue services. Mid-blue can provide a slightly lighter look while remaining smart.

Beige, stone and lighter shades may suit summer celebrations, while tweed and textured fabrics can work well for autumn or winter events.

The suit should sit neatly across the shoulders and allow the boy to move comfortably. Avoid buying excessive growing room, as an oversized jacket can look untidy in photographs and during the service.

Shirts, ties and shoes

A white formal shirt works with almost any suit. Pale blue and other subtle colours may also be suitable.

Complete the outfit with a properly sized tie or bow tie. A matching pocket square can introduce colour without overpowering the suit.

Smart black shoes coordinate well with black, charcoal, grey and navy suits. Brown or tan shoes can complement blue, beige and lighter outfits.

Browse SIRRI’s boys’ formal shirts, boys’ ties and hanky sets and boys’ brogues and Oxford shoes to complete the look.

Religious garments

A kippah, also known as a yarmulke, is a head covering commonly worn by Jewish males in the synagogue. Many synagogues provide spare kippot for guests.

The boy may also wear a tallit, or prayer shawl, depending on his community’s customs.

Tefillin are worn during weekday morning prayers in communities that follow this practice. They are not normally worn during a Saturday-morning service.

The family should follow the guidance of its rabbi or synagogue.

What Should Guests Wear to a Bar Mitzvah?

Guests should follow the invitation and any guidance provided by the family.

A synagogue service usually calls for smart, respectful clothing.

Men and boys can generally wear:

• A suit
• A blazer with smart trousers
• A collared shirt
• Smart shoes
• A tie for more formal services

Male guests may be asked to wear a kippah inside the synagogue.

Women and girls may wear a modest dress, skirt and blouse, trouser suit or other smart outfit. More traditional synagogues may have specific expectations regarding sleeves, necklines and skirt length.

Guests may change into different clothing for the party, particularly when the service takes place in the morning and the celebration is held later.

Bar Mitzvah Etiquette for Guests

Non-Jewish friends and relatives are often invited and are not expected to understand every prayer or tradition.

A few simple rules will help you attend respectfully:

• Arrive on time
• Dress appropriately
• Silence your mobile phone
• Follow the congregation when it stands or sits
• Avoid talking during prayers, readings and speeches
• Do not take photographs unless they are permitted
• Check before bringing food into the synagogue

Traditional synagogues generally do not allow photography, filming, phone use or writing during Shabbat.

“Mazel tov” is the traditional expression used to congratulate the boy and his family.

What Is an Appropriate Bar Mitzvah Gift?

Common gifts include:

• Money
• Gift cards
• Books
• Watches
• Jewellery
• Personalised keepsakes
• Religious items
• Charitable donations

Money is sometimes given in multiples of 18 because the Hebrew word chai, meaning life, has the numerical value of 18. This is a tradition rather than a requirement.

When the service takes place on Shabbat, some families may prefer guests not to bring money or gifts into the synagogue. The gift can instead be delivered before or after the day, sent to the family’s home or given at the party.

Choosing the Right Bar Mitzvah Outfit

The best bar mitzvah outfit should be formal enough for the synagogue, comfortable throughout the service and suitable for the celebration afterwards.

Shop early enough to check the fit, make adjustments and allow the boy to try the full outfit with his shirt, tie and shoes.

Explore SIRRI’s boys’ suits, formal shirts, ties and smart shoes to create a coordinated outfit for the service and celebration.

As traditions vary, families and guests should always follow the guidance of the synagogue or rabbi.
