Sefer Yetzirah · the twelve months

Two months.
A shared conversation.

Bring two Hebrew birth months together. Explore their letters and themes, read the sources, and make room for each other’s meaning.

A study in Jewish symbolism. We use the Gra version of Sefer Yetzirah, with later commentary identified separately. This is not a clinical tool, personality assessment or matchmaking verdict. These correspondences are not evidence-based predictions of whether a relationship will work. Nothing here goes into a client record.
Nothing is recorded and nothing is stored — everything happens in this browser and is gone when you reload.
A month is enough. Names are optional.

Follow the sources

A text, its readers, and our questions.

Every comparison keeps these three layers visible. You can check the original Hebrew, follow the attributed commentary, or simply explore a question together.

The primary text and the twelve-month map

Sefer Yetzirah, Gra version, chapter 5 relates twelve simple letters to months, faculties, zodiac symbols and bodily counterparts. Our month entries use sections 5:7–10, in Sefaria’s numbering. The Hebrew edition is identified there as Warsaw 1884. English labels here are our concise glosses.

The zodiac names here are the text’s symbolic month correspondences. They are not calculated Sun signs: a Hebrew lunar month does not have the same boundaries as a Western solar sign.

Why the version matters

Correspondences vary between versions. For example, the Gra version assigns Nisan the right foot, while the other Sefer Yetzirah text on Sefaria, 5:2 assigns Nisan the right hand. We keep the Gra mapping consistent and show the alternative body correspondence on each month’s source card.

Traditional body terms are preserved as symbols, not medical claims. For Shevat, we retain korkevan because English renderings vary. Tishrei’s faculty, תשמיש, is glossed here as sexual union; some later presentations broaden its language. We do not silently replace the original term.

Later commentary and what we have added

Gal Einai’s Hebrew-letter and month teachings, from Rabbi Yitzchak Ginsburgh’s teaching tradition, offer a later interpretive layer. Each month links to the specific essay used. These essays are not the base text, and their broader interpretations are not a consensus statement for all Jewish traditions.

Our relationship questions are original. The selected chapter supplies a month map, not a formula for deciding whether two people are compatible. Tribal and color correspondences, character scores, and claims to identify a soul’s destiny are not part of this version of the Lab.

Birth dates, sunset, and the two Adars

You can enter a known Hebrew birth month without supplying a birth date. For civil-date conversion, use the calendar date recorded at the birthplace. A Hebrew date changes in the evening, while the civil date changes at midnight. Select the daytime/pre-sunset option for births after midnight or during the day, and the after-nightfall option only for the evening of that civil date.

If the birth was during twilight or the timing is unknown, the tool shows both possible Hebrew dates. If those dates fall in different months, it shows both source profiles and waits for a known month before creating pair prompts. It does not calculate local sunset or determine halachic twilight boundaries.

Adar I and Adar II remain distinct calendar labels. This twelve-entry study displays the same Adar source passage for both, explicitly as an editorial grouping. Chapter 5 does not give a separate thirteenth letter/faculty entry. This is not a ruling about which Adar to use for birthdays or observances.

Calendar conversion is performed locally using the browser’s Hebrew calendar support; no geocoding, location request, or date API is used.
