What's my Jewish zodiac sign? — your Hebrew birthday, computed

Begin Your Full ReadingThe Hebrew calendar is lunisolar: months follow the moon, years are pinned to the seasons with leap months. Against the fixed Gregorian grid, everything drifts — so the Western sign windows (March 21 – April 19 and the rest) slice across two Hebrew months each, differently every year. Two people who share a sun sign routinely carry different mazalot. The mazal, in turn, comes with a tribe, a letter, and one of the twelve senses of Sefer Yetzirah ch. 5 — a fuller anatomy than a sun sign, and in the tradition's own words, never a verdict: ein mazal l'Yisrael.
What is my Jewish zodiac sign?
Your Jewish zodiac sign (mazal) is determined by the Hebrew month you were born in — not by the sun's position like Western astrology. Enter your Gregorian birth date above and the calculator converts it to your Hebrew birthday and shows your month's mazal, tribe, and letter.
How do I convert my birthday to the Hebrew calendar?
The Hebrew calendar is lunisolar, so conversion requires real arithmetic — this calculator runs the full classical algorithm (the same one behind our readings) in your browser. One nuance: the Jewish day begins at sunset, so if you were born after sunset your Hebrew date is the following day. Use the toggle.
Is the Jewish zodiac the same as regular astrology?
No. The months carry mazalot — Aries through Pisces have Hebrew names and month assignments in Sefer Yetzirah — but the tradition reads them as temperament and avoda (inner work), not prediction, and rules that ein mazal l'Yisrael: the pattern never overrides free choice.
