Lag BaOmer — ל״ג בעומר
Sunset May 24, 2027 and ends at sunset May 25, 2027.
Summary
Lag BaOmer is a joyful Jewish day observed on the 18th of Iyar, the 33rd day of Sefirat HaOmer, the counting period between Pesach and Shavuot.
The name Lag comes from the Hebrew letters ל and ג. The letter lamed has the numerical value of 30 and gimel has the value of 3, giving us 33. BaOmer means “in the Omer.”
Lag BaOmer occurs during a period when many Jewish communities observe customs of mourning. According to rabbinic tradition, thousands of students of Rabbi Akiva died during this period because they failed to treat one another with proper respect. Lag BaOmer became associated with the ending or interruption of that tragedy.
The day is also strongly connected with Rabbi Shimon bar Yochai, one of the great sages of the Mishnah and an important figure in Jewish mystical tradition. According to longstanding tradition, Lag BaOmer is the anniversary of his death, known as his hillula. He is traditionally associated with revealing deep teachings of Torah and with the Zohar.
Because of these traditions, Lag BaOmer is celebrated with Torah learning, outdoor gatherings, music, weddings according to community custom, children’s activities, and large celebrations in Israel. Bonfires have become especially associated with the holiday, particularly in Israel.
The largest traditional gathering takes place at the tomb of Rabbi Shimon bar Yochai in Meron in northern Israel, where large numbers of Jews gather for prayer, Torah learning, singing, and celebration.
Lag BaOmer is not a Yom Tov like Pesach or Sukkot. Work is permitted, there is no Kiddush specifically for the day, and there are no special restrictions on driving or using electricity.
The Omer — העומר
Lag BaOmer takes place during Sefirat HaOmer.
The Torah commands us to count seven complete weeks beginning during Pesach and continuing until Shavuot.
Each evening, Jews count another day.
For example:
היום שלושה ושלושים יום שהם ארבעה שבועות וחמישה ימים לעומר
Hayom sheloshah ushloshim yom, shehem arba’ah shavuot vachamishah yamim laOmer.
“Today is thirty-three days, which are four weeks and five days of the Omer.”
That is the count for Lag BaOmer.
The Omer creates a spiritual connection between Pesach and Shavuot.
Pesach celebrates freedom from Egypt.
Shavuot celebrates receiving the Torah at Har Sinai.
The weeks between them remind us that freedom has a purpose. We were freed from Pharaoh so that we could become a people living according to HaShem’s Torah.
Why Is the Omer a Period of Mourning?
Although the Omer begins with Pesach and ends with Shavuot, much of the period has a more serious character.
The Talmud teaches that 12,000 pairs of students of Rabbi Akiva, traditionally understood as 24,000 students, died during a period between Pesach and Shavuot.
The Talmud explains that this tragedy occurred because:
לא נהגו כבוד זה לזה
Lo nahagu kavod zeh lazeh.
“They did not treat one another with respect.”
This teaching is especially powerful because these were Torah students.
They were people who were learning Jewish law and tradition.
Yet Torah knowledge alone was not enough if they failed to treat one another properly.
Rabbi Akiva — רבי עקיבא
Rabbi Akiva was one of the greatest sages in Jewish history.
He lived during the Roman period and became one of the most important teachers of the Oral Torah.
One of the teachings most strongly associated with him is:
ואהבת לרעך כמוך
V’ahavta l’reacha kamocha.
“You shall love your neighbor as yourself.”
Rabbi Akiva called this a great principle of Torah.
That makes the death of his students especially meaningful.
They studied under a teacher who placed enormous importance on how people treat one another, yet according to the Talmud they failed in precisely that area.
Lag BaOmer therefore gives us an opportunity to think about whether our own Torah observance is making us more respectful toward other people.
What Happened on Lag BaOmer?
Traditional Jewish practice associates Lag BaOmer with a pause or conclusion in the deaths of Rabbi Akiva’s students.
The exact historical details and timing are discussed differently among Jewish authorities and communities.
This is one reason mourning customs do not end on exactly the same day for every Jewish tradition.
For many Ashkenazi Jews, Lag BaOmer itself marks the major break in the mourning period.
Many Sephardic communities continue certain mourning practices until the morning of the 34th day of the Omer.
Other customs exist as well.
This is an important example of legitimate differences within Orthodox Jewish practice.
Mourning Customs During the Omer
During portions of the Omer, many Orthodox Jews avoid weddings, live music, and haircuts.
These customs commemorate the deaths of Rabbi Akiva’s students.
The exact days observed differ.
Some communities observe mourning from Pesach until Lag BaOmer.
Others observe a later part of the Omer.
Some Sephardic communities continue restrictions through the 33rd day and permit haircuts and weddings beginning on the morning of the 34th.
A person should generally follow their family or community tradition.
Lag BaOmer and Weddings
Lag BaOmer is a popular day for Jewish weddings, especially in Ashkenazi communities.
Because many mourning restrictions are suspended or end on Lag BaOmer, couples often choose this day to marry.
In Israel, it is common to see many weddings around Lag BaOmer.
Sephardic practice can be different.
According to a widespread Sephardic custom, weddings and haircuts are not resumed until the 34th day of the Omer.
However, Sephardic communities still recognize Lag BaOmer as a special and joyful day.
Rabbi Shimon bar Yochai — רבי שמעון בר יוחאי
Lag BaOmer is also deeply associated with Rabbi Shimon bar Yochai, often called Rashbi.
Rashbi was a student of Rabbi Akiva and one of the important sages whose teachings appear throughout the Mishnah and Talmud.
Jewish tradition describes him as a great Torah scholar with a particularly deep understanding of the hidden dimensions of Torah.
He became especially important within Kabbalistic tradition.
Rashbi and the Romans
According to the Talmud, Rabbi Shimon bar Yochai spoke critically of Roman rule.
Because of this, the Romans sought to arrest him.
He and his son Rabbi Elazar hid in a cave for many years.
Traditional accounts describe them studying Torah while living there under extraordinary conditions.
When they eventually emerged, their intense spiritual life had changed how they viewed the ordinary world around them.
The story contains important lessons about Torah study, spiritual intensity, and learning how to live holiness within ordinary human society.
The Zohar — הזוהר
Rabbi Shimon bar Yochai is traditionally associated with the Zohar, one of the central texts of Kabbalah.
The word Zohar means “radiance” or “splendor.”
The Zohar explores mystical interpretations of Torah, the nature of HaShem’s interaction with creation, the soul, mitzvot, and many other spiritual subjects.
Traditional Jewish belief strongly associates the teachings of the Zohar with Rashbi, although the written history of the text is complex.
Lag BaOmer therefore became especially important among communities influenced by Kabbalah.
The Hillula of Rabbi Shimon bar Yochai
According to Kabbalistic tradition, Lag BaOmer is the anniversary of Rashbi’s death.
The anniversary of the death of a righteous person is sometimes called a hillula.
Rather than treating Rashbi’s anniversary only as a day of sadness, the tradition celebrates the Torah he revealed and the spiritual legacy he left behind.
According to tradition, Rashbi revealed important mystical teachings shortly before his death.
This association with Torah and spiritual light helps explain why fire and light became important symbols of Lag BaOmer.
Meron — מירון
The most famous Lag BaOmer celebration takes place in Meron in northern Israel.
Rabbi Shimon bar Yochai and his son Rabbi Elazar are traditionally buried there.
Large numbers of Jews travel to Meron around Lag BaOmer.
People pray.
They study Torah.
They sing traditional songs.
Many participate in celebrations honoring Rashbi.
The gathering attracts Orthodox Jews from many different backgrounds, including Ashkenazi, Sephardic, Mizrahi, Chasidic, and Religious Zionist communities.
Bonfires — מדורות
Bonfires have become one of the most recognizable customs of Lag BaOmer, especially in Israel.
In Hebrew, a bonfire is called:
מדורה
Medurah.
The fires are often connected symbolically with the spiritual light of Torah and the teachings associated with Rabbi Shimon bar Yochai.
On the night of Lag BaOmer, bonfires can be seen throughout Israeli neighborhoods and communities.
Children and families may gather around them for food, songs, and conversation.
Bonfires are a custom rather than a mitzvah.
They should also be handled carefully. Jewish celebration does not remove the responsibility to protect life and prevent fires or injuries.
Fire as a Symbol of Torah
Fire appears many times in Jewish tradition.
Torah is compared with light.
The giving of the Torah at Har Sinai involved fire.
A flame can illuminate a dark place without losing its own light.
This makes fire a natural symbol for Torah learning.
One person can teach Torah to another person.
That person can then teach someone else.
The original teacher has lost nothing.
The light simply grows.
Chalaka or Upsherin
Lag BaOmer is also associated with the first haircut of a young Jewish boy in several Orthodox communities.
The child is often around three years old.
Ashkenazi and Chasidic communities may call this an upsherin.
Sephardic and Mizrahi communities often use the term:
חלאקה
Chalaka.
Families sometimes travel to Meron to give a boy his first haircut near the tomb of Rabbi Shimon bar Yochai.
The child may begin wearing visible peyot according to family tradition.
The event often marks the beginning of a new stage in the child’s Jewish education.
Beginning Torah Education
Around the time of a child’s first haircut, families may begin introducing more formal Jewish learning.
A child may begin learning Hebrew letters.
Some families introduce a kippah or tzitzit more consistently.
The exact customs differ.
The basic idea is that the child is moving from very early childhood toward greater participation in Jewish life.
This makes Lag BaOmer particularly joyful for families celebrating a chalaka.
Archery
Another traditional Lag BaOmer activity in some communities is archery.
One explanation connects the bow with a tradition that no rainbow appeared during Rabbi Shimon bar Yochai’s lifetime because his righteousness protected the generation.
The Hebrew word for a bow, keshet, also means rainbow.
Other explanations connect bows and arrows with Jewish resistance during the Roman period.
Today, archery is mostly a cultural or educational Lag BaOmer activity rather than a religious requirement.
Outdoor Activities
Lag BaOmer is often celebrated outdoors.
Children may have school outings.
Families may gather in parks.
Communities may organize picnics or outdoor Torah programs.
This has made Lag BaOmer one of the more informal and social days of the Jewish calendar.
For someone who feels uncomfortable attending a formal synagogue service, a Lag BaOmer community gathering can sometimes provide an easier way to meet other Jews.
Torah Learning
Torah learning is an especially appropriate way to observe Lag BaOmer.
Some people study teachings of Rabbi Shimon bar Yochai.
Others learn sections of the Zohar if they have the proper background.
Many learn ordinary Torah, Mishnah, Gemara, or teachings about Rabbi Akiva.
The day should not become only a barbecue or bonfire.
Its deeper meaning is connected with Torah and Jewish spiritual growth.
Ashkenazi Observance
In many Ashkenazi communities, Lag BaOmer brings a clear break from the mourning customs of the Omer.
Haircuts may be taken.
Weddings may be held.
Music and celebrations resume according to the community’s custom.
Chasidic communities may hold large celebrations called tishen or gatherings connected with Rabbi Shimon bar Yochai.
Children may participate in outings, parades, bonfires, or archery activities.
For some Ashkenazi families, a boy’s upsherin may also take place on Lag BaOmer.
Sephardic Observance
Sephardic communities often have a particularly strong connection with Rabbi Shimon bar Yochai and Kabbalistic traditions.
The celebration of Rashbi’s hillula can therefore be very important.
Some families light candles in his honor.
People may study Zohar or other Torah teachings.
Piyutim connected with Rashbi may be sung.
A famous song heard in many Sephardic and Mizrahi communities is Bar Yochai, written in honor of Rabbi Shimon bar Yochai.
At the same time, many Sephardic communities continue the formal Omer mourning restrictions until the morning of the 34th day.
This means Lag BaOmer may be joyful even though some restrictions remain until the next morning.
Mizrahi Observance
Many Mizrahi communities share the Sephardic reverence for Rabbi Shimon bar Yochai.
Jews from Morocco, Iraq, Syria, Iran, Kurdistan, and other communities may celebrate with Torah learning, songs, meals, and gatherings.
The melodies and piyutim can vary significantly.
North African Jewish traditions developed especially strong customs surrounding the hillulot of righteous rabbis.
For those communities, the hillula of Rashbi fits naturally within a broader tradition of gathering to honor Torah scholars and tzaddikim.
Many Mizrahi families also follow Sephardic halachic rulings concerning the Omer mourning period.
Bar Yochai — בר יוחאי
One of the best known songs connected with Lag BaOmer is Bar Yochai.
It was composed by Rabbi Shimon Lavi, a 16th-century Kabbalist.
The song praises Rabbi Shimon bar Yochai through mystical language.
It is especially popular among Sephardic and Mizrahi communities but has also become widely sung throughout the Jewish world.
At Meron, it is one of the songs strongly associated with the celebration.
Lag BaOmer in Israel
Lag BaOmer is especially visible in Israel.
In the days before the holiday, children traditionally collect wood for bonfires.
On the evening of Lag BaOmer, fires can appear throughout neighborhoods.
Schools may hold outings or special programs.
Religious communities organize Torah learning and celebrations.
Many people travel north toward Meron.
Lag BaOmer is not an official work-free Yom Tov, so businesses and workplaces generally operate normally.
Is Work Permitted?
Yes.
Lag BaOmer is not Shabbat or Yom Tov.
There is no general prohibition against working.
Driving is permitted.
Electricity can be used.
Cooking is allowed.
People may attend school or work.
The special character of the day comes through celebration, Torah learning, community activities, and the relaxation of certain Omer mourning customs according to one’s tradition.
There Is No Special Kiddush
There is no special Kiddush required for Lag BaOmer.
There is also no unique holiday meal required by halachah.
Families and communities may certainly have festive meals.
A gathering may include grilled food, traditional dishes, sweets, or other foods.
These are customs and community celebrations rather than required mitzvot.
Tachanun
Tachanun, the penitential prayer, is generally omitted on Lag BaOmer.
This reflects the joyful character of the day.
There are also customs concerning whether Tachanun is omitted at Mincha the afternoon before.
The exact practice should follow the synagogue’s tradition.
Lag BaOmer and Jewish Unity
The tragedy of Rabbi Akiva’s students gives the day an important message about Jewish unity.
According to the Talmud, they were punished because they did not show proper respect to one another.
That should cause us to think seriously about how Jews treat other Jews.
We can disagree about politics.
We can have different synagogue traditions.
Our families may be Ashkenazi, Sephardic, Mizrahi, Yemenite, Ethiopian, or from somewhere else.
Some Jews are Orthodox.
Others are traditional or secular.
Difference does not require disrespect.
Lag BaOmer reminds us that Torah learning should make us better at seeing the value of another person.
Respect Does Not Mean Agreement
The lesson about Rabbi Akiva’s students does not mean Jews must agree on everything.
Jewish tradition is filled with disagreements.
The Talmud itself records arguments between great rabbis.
The question is how we disagree.
We can disagree strongly while remembering that another Jew is still part of Am Yisrael.
Respectful disagreement is very different from humiliation, hatred, or treating another person as though they have no value.
Lag BaOmer and Spiritual Light
The image of light is especially meaningful for someone who feels distant from Jewish life.
A person does not need to understand all of Torah before beginning.
A small amount of light matters.
Learn one idea.
Say one brachah.
Perform one mitzvah.
Attend one Jewish gathering.
Meet another Jew.
What begins as curiosity can become something much deeper.
Lag BaOmer reminds us that Torah is something we can share without diminishing it.
The more people who learn, the more light there is.
Lag BaOmer for Someone New to Jewish Observance
Lag BaOmer can be an easy way to experience Jewish community.
Attend a community gathering.
Go to a picnic.
Listen to Jewish music.
Learn something about Rabbi Akiva or Rabbi Shimon bar Yochai.
If there is a safe community bonfire, participate.
Ask why people are celebrating.
You do not need to know an entire prayer service before joining.
The social nature of the day can make it especially welcoming to someone who feels nervous about entering a synagogue.
A Tevel Zion Lesson From Lag BaOmer
Lag BaOmer brings together two powerful Jewish ideas.
One comes from the students of Rabbi Akiva.
Torah learning means very little if we cannot learn to treat one another with respect.
The other comes from Rabbi Shimon bar Yochai.
Torah can bring light into places that otherwise feel dark.
These lessons belong together.
A Jewish community should be a place where people can learn Torah without being embarrassed about what they do not know.
It should be a place where an observant Jew can sit beside someone who is just beginning to explore Judaism.
It should make room for Ashkenazi, Sephardic, and Mizrahi traditions.
Someone who feels alone should be able to come to a gathering and discover that there is a place for them.
We do not strengthen Judaism by making people afraid to ask questions.
We strengthen it by teaching Torah, performing mitzvot, respecting one another, and helping people move closer to HaShem.
A single flame may seem small.
But one person can light another flame without losing any of their own light.
That person can light another.
Eventually, what began as one small flame can illuminate an entire community.
That may be one of the most meaningful lessons of Lag BaOmer.
