Converting between Hebrew and Gregorian dates is a daily necessity in Israel, whether for holidays, yahrzeits, bar/bat mitzvahs, or event planning. The Hebrew calendar is based on complex lunar cycles with leap years, and there is no simple formula for conversion. Existing online tools rarely offer an API and require manual lookups each time.
