       hdate - displays Hebrew date information for a given Gregorian/Julian date


       hdate [options] [coordinates [timezone]] [[[dd] mm] yyyy]

       hdate [options] [coordinates [timezone]] [ julian_day ]

       coordinates: -l [NS]yy[.yyy] -L [EW]xx[.xxx]
                           -l [NS]yy[:mm[:ss]] -L [EW]xx[:mm[:ss]]
              timezone:    -z nn[( .nn | :mm )]


       hdate translates the specified date to the Hebrew calendar and optionally displays further
       information about that Hebrew date, including holidays and astronomical-related times (see
       section  LOCATION,  below).  If  no  arguments  are given, it displays information for the
       current date. If a single numeric argument is given, it will be interpreted as a year, and
       hdate  will  output  the  requested  information for all days of that year. If two numeric
       arguments are given, it will be  interpreted  as  mm  yyyy,  and  hdate  will  output  the
       requested information for all days of that month.

       INPUTTING  A  HEBREW DATE: If the year provided is greater than 3000, hdate will interpret
       the given date as a Hebrew date,  and  will  display  information  for  the  corresponding
       Gregorian  date.  Hebrew  months  are  expected to be passed as numbers 1-12 for Tishrei -
       Elul; Adar I and Adar II are expected to be passed as months 13 and 14.

       INPUTTING A JULIAN DAY: If a single numeric argument is provided, and it is  greater  than
       348021,  hdate  will  interpret it as the "Julian day number" and will display information
       for the corresponding Hebrew date.

       If you want hdate to display accurate time-of-day information, hdate requires location and
       time  zone information in order to make astronomical calculations for a given date. If you
       don't provide ANY such information, hdate uses your computer's local time zone information
       as  an indicator, and either picks a city in that time zone, or defaults to the equator at
       the center of that time zone. If hdate can't even retrieve time zone information from your
       computer,  it  defaults  to  Tel-Aviv. For other locations, use the -l -L option pair. For
       other timezones, use the -z option. Co-ordinates and standard time zones for  some  common
       locations are listed below.

       The current defaults include:
                Timezone   Default city    Lattitude  Longitude
                   -5      New York City      40        -74

       Accuracy  The accuracy of the astronomically-derived data will suffer from not  accounting
                 for  environmental  conditions  such  as elevation, horizon, temperature and air

       Timezones The timezone support is currenlty  primitive  and  lacks  support  for  daylight
                 savings time transitions.

                 The  software  does  not yet account for the phenomenon and complications of the
                 "Gregorian transition" from the prior, Julian calendar, which effectively caused
                 an  instantaneous  'loss' of two weeks for all gentiles affected. Countries (eg.
                 Poland, Spain and Italy) began adopting the Gregorian calendar on 8 Tishrei 5343
                 (4  October  1582CE),  although  many  did not transition until the 56th century
                 (1752 CE, eg. UK colonies, Sweden). Russia did not adopt the Gregorian  calendar
                 until  5678  (1918  CE)  and Turkey did not until 5687 (December, 1926 CE). Many
                 other countries made the transition on other dates. Keep  in  mind  that  Russia
                 invaded  part  of Poland, undoing, for the interim, the Gregorian transition for
                 (only) that part of Poland; Also important to remember in this  regard  is  that
                 Eretz  Ysroel  was  part of the Turkish Ottoman empire until the British mandate
                 (5677 (1917CE)). Until all this is accounted for adequately by this application,
                 refer  to ' ncal -p ยด for a basic table of country transitions. However, keep in
                 mind that European borders underwent  many  changes  during  the  426  years  in
                 question,  so  the  accuracy  of  your data will depend on accurate knowledge of
                 whether any particular date at any specific location was Julian or Gregorian.

       project page:

       hcal and hdate are part of the package libhdate , a small C/C++ library for Hebrew  dates,
       holidays,  and  reading  sequences (parashiot). It uses the source code from Amos Shapir's
       "hdate" package, as fixed and patched by Nadav Har'El. The Torah reading  sequence  tables
       were contributed by Zvi Har'El.
