       hdate - Hebrew date and calendar

       example programs for libhdate, a library that help use Hebrew dates.

       LibHdate  is  a  small  C,C++  library  for Hebrew dates, holidays, and
       reading sequence (parasha). It is  using  the  source  code  from  Amos
       Shapir’s  "hdate"  package fixed and patched by Nadav Har’El. The Torah
       reading sequence is from tables by Zvi Har’El.


       hdate [-sctShHrRjdi]

       [-L longitude -l latitude] [-z timezone]

       [[[day] month] year]/[julian_day]


       Hdate translates the specified date to  the  Hebrew  calendar.   If  no
       arguments are given, it uses today’s date.  ‘month’ is a number between
       1 and 12.

       If the year is greater than 3000 hdate takes the given date as a Hebrew
       date,  and  translates  it  back to the common calendar. If argument is
       greater than 100000 hdate takes it as the Julian  day  number.   Months
       are  numbered  with Tishrey being 1 and Elul 12; Adar I and Adar II are
       months 13 and 14.
