Frequently Asked Questions
A Jewish birthday follows the Hebrew calendar, which is lunisolar. It is the anniversary of a person's birth according to the Hebrew date.
The calculator uses the JavaScript Intl.DateTimeFormat with the 'hebrew' calendar option to convert dates. It then finds the next occurrence of the same Hebrew month and day.
In rare cases, due to calendar complexities (e.g., leap months), the algorithm may not find a match within the iteration limit. Try a different date or consult a rabbinical calendar.
