Dates, letters and natal positions
A Hebrew date conversion identifies a day, month and year. Gematria adds the numeric values of Hebrew letters using a named method. The optional natal view in the birthday tool computes tropical Sun and Moon positions from a date, with time-zone and uncertainty notes. These calculations answer different questions.
A Hebrew birth-month correspondence follows the named Gra version of Sefer Yetzirah; it is a symbolic association rather than the computed position of a planet. A reflection does not establish a prediction or a personality fact. Keep that distinction when comparing results.
The free calculations run in your browser. You can use them without an account or payment.
