In a common Sefer Yetzirah correspondence, Tammuz is paired with Cancer (Sartan) and the Hebrew letter ח Chet. In the Gra-version ordering, the letter is also associated with the faculty of sight. Ava Lux treats this as a textual correspondence first and a modern interpretive prompt second.

The textual correspondence
Sefer Yetzirah organizes twelve simple Hebrew letters alongside twelve zodiacal constellations and twelve months. In the ordering used here, Chet corresponds with Tammuz and Cancer. Different textual recensions and later commentaries can order some secondary correspondences differently, which is why Ava Lux names the version instead of presenting one chart as universally uncontested.
Tammuz in the Jewish calendar
Tammuz contains the Fast of the Seventeenth of Tammuz and begins the Three Weeks in the Jewish calendar. Tammuz is the fourth month when counting from Nissan. The month therefore carries a Jewish historical and ritual context that cannot be reduced to a generic zodiac personality profile.
Cancer as a modern astrological layer
Modern astrology associates Cancer with memory, protection, family, emotional reactivity and belonging. Those meanings belong to the later astrological interpretive tradition. They are not literal definitions supplied by Sefer Yetzirah.
The Chet layer
In the Gra-version ordering used by Ava Lux, Chet is associated with sight. The value of the correspondence is not that one Hebrew letter “proves” a personality trait. It creates a second symbolic question beside the zodiac sign.
Ava Lux reflection for Tammuz
The letter-sense of sight offers a useful counterpoint to emotional immediacy: what becomes visible when reaction is observed before it is obeyed?
Finding your Hebrew month
Your Hebrew month must be calculated from the actual birth date. Because the Jewish day begins in the evening, a birth near sunset may require the exact local time and place to determine the correct Hebrew date.

Ava Lux editorial rule: source texts, later Kabbalistic interpretation, modern astrology and the Ava Lux reading method are not treated as if they were the same layer. Where traditions disagree or textual versions vary, the page says so.
