Av — the Hebrew month of Leo
Av is the month of the lion and the month of mourning — the same fire that built the Temple is the fire that reduced it to ash. To be born here is to carry that double inheritance in your own chest.
You learned what your anger could do before you were old enough to name it. Somewhere in childhood a door slammed, a voice rose, a room went quiet around you, and you concluded — wrongly, but completely — that the heat in you was dangerous and had to be put away. So you put it away. You became easy to be around. You traded the fire for approval, and you have spent most of your adult life in a slow, private negotiation to get some of it back. People born in Av tend to arrive as two people who do not fully introduce each other: one warm, generous, almost incapable of leaving a person un-helped, and one fierce, exacting, capable of a contempt that surprises even you. Most who know you have met only the first. The ones who eventually met the second often left — not because the fire was new, but because they had decided you were the warmth and felt the heat as a betrayal. It was not new. It was the half you had been guarding.
This is the central fact of your month, and it is worth saying plainly before anything mystical: your fire was never the problem your family told you it was. It is the gift they did not know how to hold. The work of a lifetime, for someone born here, is not to extinguish it but to aim it.
The Lion in Summer
The mazal of Av is Leo — אַרְיֵה, the lion. Of all the signs this is the least ambiguous and the least apologetic. A lion does not perform smallness to make a room comfortable; its presence is a fact others arrange themselves around. That is the temperament you were issued. Av falls at the height of summer, when the sun is most direct and least negotiable, and the season suits the sign: there is nothing dim or hedged about it. But the lion is also why your defining tension is so sharp. Strength that has nowhere righteous to go does not evaporate — it curdles. The same intensity that makes you magnetic in a cause makes you frightening in a quarrel. You do not have a quiet setting; you have a directed one and an undirected one, and the difference between them is everything.
Simeon: The Cost of Zeal
Your tribe is Simeon, and the tribal story is not flattering — which is precisely why it is useful to you. Simeon, with Levi, took up the sword at Shechem in defense of their violated sister, and their father Jacob did not bless the deed; on his deathbed he named their wrath and scattered them. This is the inheritance of Av rendered as biography: fierce loyalty, real cause, and a zeal that overshoots the mark and damages what it meant to protect. Simeon is the cautionary half of your month. The point is not that the anger was baseless — it was not — but that passion without restraint becomes its own kind of destruction, and the destruction outlives the grievance. You will recognize this pattern in yourself if you are honest: the times you were right and still lost something because of how you carried being right.
Tet, and the Discipline of Hearing
Sefer Yetzirah assigns to Av the letter ט, Tet — the first letter of טוֹב, tov, good — and the tradition reads Tet as good that is hidden, folded inward, not yet visible. That is an exact description of your fire before it is aimed: a buried good, easily mistaken for a flaw. The faculty given to your month is hearing. This is no accident in the month of Tisha b'Av, when both Temples fell and the verse most associated with the season is שְׁמַע — Shema, hear. For a lion, hearing is the hardest of the senses, because hearing requires that for a moment you are not the one speaking, not the one acting, not the one already certain. Your rectification is the half-second before reaction: the readiness to truly take in what another person is saying before you decide what it means. The destruction of Av is traditionally tied to baseless hatred — to people who had stopped listening. Your repair is the opposite motion, made on purpose.
And there is the other pole of the month, which the tradition refuses to forget: the fifteenth of Av, called the most joyful day in the calendar — the same lion-fire turned toward union, abundance, and repair. Av is not the month of mourning or the month of joy. It is the month where the distance between the two is shortest, and the bridge is yours to build.
Where the Fire Lands at Work and at Home
Channeled, you are unmistakable. You do not manage so much as galvanize; people follow you into things they would not have attempted alone, because your conviction reads as permission. Your charisma is real, your fearlessness is real, and your capacity to make others feel larger in your presence is the rarest of your gifts. The roles that fit the lion are the ones that require someone unafraid to stand in front:
- Leader of a movement or founder of a venture — anywhere a cause needs a face
- Activist or trial lawyer — fight given structure and a verdict
- Director or brand builder — vision imposed on a room until it becomes shared
The growth edges are the inverse of the strengths, as they always are with a strong sign. Humility, because conviction this confident rarely checks itself. Restraint, because the same force that inspires can flatten. And above all the discipline of listening before you judge — of letting someone finish, of granting that your first reading of an offense might be wrong. In love this is the whole story: the people worth keeping are the ones who saw both halves of you and stayed, and you keep them not by hiding the fire but by being trustworthy with it. The fire is not the danger. The fire that has nowhere to go is. Give it Torah, give it a cause, give it the people you would protect — and the lion that could burn a Temple becomes the one that builds it.
Av in the Classical Sources: A Deeper Map
In Hebrew the sign is מַזָּל אַרְיֵה — mazal Aryeh, the Lion — and the month is חוֹדֶשׁ אָב, chodesh Av, whose name simply means "father." Av is the only Hebrew month the Talmud discusses in explicitly astrological language — it is the one place the Sages say outright that the month's mazal runs weak — and it is also the month the tradition insists will one day outrank every other in joy. Both facts belong in the file.
Sefer Yetzirah: Letter, Tribe, and Faculty
The fifth chapter of the סֵפֶר יְצִירָה assigns Av the letter ט (Tet), the tribe of Shimon, and the faculty of hearing. Tet is the letter whose first appearance in the Torah opens the word tov, "good" — the Sages call it the letter of concealed good, a shape coiled inward like a vessel holding its contents out of sight. Shimon is named for hearing itself: his mother Leah declared, "Because the Lord heard…" — and the tribe's history is a study in what happens when hearing goes unrefined. The month's faculty completes the pattern: Av's catastrophe began with listening — a nation accepted the spies' report and wept on the ninth of Av over a slander — so Av's repair is the discipline of the ear. Classical astrology gives Aryeh to חַמָּה (Chamah, the Sun) itself: the king-star for the king of beasts, full light in the month of deepest dark.
The Talmud: The Month Whose Mazal Runs Weak
Ta'anit 29a rules: "When Av enters, we diminish joy." And the Gemara that follows is the most explicitly astrological line in the Talmud: an Israelite with a lawsuit against a gentile should avoid Av, "whose mazal is bad" (רֵיעַ מַזָּלֵיהּ), and move the case to Adar, "whose mazal is healthy." The Sages, who ruled that Israel stands above the stars, still tell you not to schedule your court date under the lion. That tension — influence is real, sovereignty is realer — is the entire Jewish theory of mazal compressed into one page of Talmud. And the same tractate holds the month's other pole: "There were no better days for Israel than the fifteenth of Av and Yom Kippur" — the month of the deepest fast contains the calendar's most joyful day, six days apart.
The Maharal: Why the Eternal Cannot Burn
The Maharal's Netzach Yisrael — "the Eternity of Israel" — is a book-length meditation on Av's central event. His argument runs against every intuition of grief: the destruction of the Temple, he writes, is itself the demonstration of Israel's permanence. Whatever can be destroyed was, by definition, not the essence; the essence is what remains when everything burnable has burned. The Midrash the Maharal builds on says the lion came in the month of the lion to destroy the dwelling of the Lion — so that the Lion of Judah could rebuild it. Av-born souls carry that architecture natively: a strength that is proven, not disproven, by what it survives.
The Bnei Yissaschar: The Month's Avodah
The Bnei Yissaschar's essays on Av (treated together with Tammuz as one season of repair) turn on the month's name: Av means father, and even the month of harshest judgment is signed as a parent — its severity a father's severity, never an executioner's. He teaches that the month's avodah is refined hearing: the ninth of Av came through accepting evil speech, so the month's repair is to become an ear that filters — quick to hear another's pain, deaf to another's disgrace. The lion's roar, in his reading, is not rage but announcement: the tradition holds that Mashiach is born on Tisha B'Av — the redeemer conceived in the wound itself.
Above the Stars
Av is where ein mazal l'Yisrael (Shabbat 156a) is tested hardest and proven best: the Talmud concedes this month's mazal runs weak — and the same tradition promises the month will become the calendar's greatest festival. A fate that is scheduled for reversal was never a fate; it was a season. The full teaching is at Ein Mazal L'Yisrael: Why the Jewish Zodiac Is Not Fate; the complete map is at the twelve Jewish zodiac signs.
What zodiac sign is the Hebrew month of Av?
Av corresponds to Leo, called Aryeh (אַרְיֵה) in Hebrew, whose symbol is the lion. It is a summer month, roughly July to August.
Which tribe is associated with Av?
Av is associated with the tribe of Simeon. Simeon's story — fierce, loyal, and zealous to a fault at Shechem — embodies the month's theme of passion that must be channeled rather than unleashed.
What is the personality of someone born in Av?
People born in Av tend to be strong, passionate, and leonine — magnetic and fearless, but capable of both holy zeal and destructive anger. Their lifelong work is aiming that fire toward kindness and purpose, and their inner repair is learning to truly listen before reacting.
When does the Hebrew month of Av fall in the Gregorian calendar?
Av falls in midsummer, roughly July into August. It contains Tisha b'Av, mourning the destruction of both Temples, and the fifteenth of Av, considered the most joyful day in the Jewish calendar.
What is mazal Aryeh (מזל אריה)?
Mazal Aryeh (מַזָּל אַרְיֵה) is the Hebrew name for Leo, the Lion — the sign of Av (חודש אב). The Midrash reads it as the month's whole account: the lion (Babylon) came in the month of the lion to destroy the Lion's dwelling, so that the Lion of Judah would one day rebuild it.
Does the Talmud really say Av has weak mazal?
Yes — Ta'anit 29b advises an Israelite with a lawsuit to avoid Av, 'whose mazal is bad' (ריע מזליה), and to choose Adar, 'whose mazal is healthy.' It is the Talmud's most explicit astrological statement — held together with Shabbat 156a's ruling that Israel ultimately stands above the mazal.
