Convert between Gregorian and Hebrew (Jewish) calendar dates.
- Gregorian → Hebrew: pass gregorian_date (YYYY-MM-DD). Add end_date to convert a whole range (max ~180 days).
- Hebrew → Gregorian: pass hebrew_year, hebrew_month, hebrew_day.
Set after_sunset=true when the Gregorian time is after sunset (the Hebrew date advances at nightfall).
Returns the Hebrew date in English and Hebrew letters plus any holidays/events on that day.
