Hebcal's converter turns any Gregorian date into its Hebrew-calendar equivalent, returning the Hebrew year, month and day plus the Hebrew-script date and any Torah portion or holiday that falls on it. Pass cfg=json to get structured output. The wider Hebcal API also covers Shabbat and holiday times.
