NAME

       hcal - displays a Hebrew / Gregorian calendar

SYNOPSIS

       hcal [options] [coordinates [timezone]] [[mm] yyyy]

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

DESCRIPTION

       hcal  prints  a  calendar with both Gregorian and Hebrew dates for the specified Gregorian
       month or, if no month is specified, for the whole Gregorian  year.  If  no  arguments  are
       given,  it  prints  the  current  month's calendar. Jewish holidays are annotated, and can
       optionally be footnoted.  hcal tries to be sunset-aware in order  to  correctly  highlight
       the  current Hebrew date, and can also display Shabbat times and parshiot. See the section
       LOCATION, below.

       INPUTTING A HEBREW DATE: If the year provided is greater than 3000,  hcal  will  interpret
       the  given  date  as  a  Hebrew  date,  and will display the calendar of the corresponding
       Gregorian month(s). 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.

NOTES

   HOLIDAYS
       Holidays are depicted by a change in the symbol separating a day's  Gregorian  and  Hebrew
       dates, as follows:

              /  Regular day
              +  Yom Tov (plus Yom Kippur)
              *  Erev Yom Kippur
              ~  Hol HaMoed
              !   Hanuka and Purim
              @  Tzomot
              $  Lag BaOmer ,Tu BeAv, Tu BeShvat
              #  Independance day and Yom Yerushalaim
              %  Tzahal and Holocaust memorial days
              ^  Other Israeli National days

       Use the -f (--footnote) option to have hcal describe what any particular day is marking.

   LOCATIONS
       If  you  want hcal to display accurate Shabbat times, and to accurately advance the Hebrew
       'today's date' indicator at sunset, hcal requires location and time  zone  information  in
       order  to  make  astronomical calculations for a given date. If you don't provide ANY such
       information, hcal 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 hcal 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
                    0      London             51          0
                    1      Paris              48          2
                    2      Tel-Aviv           32         34
                    3      Moscow             55         37

   CONFIG FILE
       This  folder  and  file will be automatically created, and includes its own documentation,
       in-line:
                       ${XDG_CONFIG_HOME}/hcal/hcalrc

                       ~/.config/hcal/hcalrc

BUGS

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

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

       Historical
                 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.

EXAMPLES

       1. Display a 2012ce year's calendar, three-months wide, in color.
             hcal -3c 2012

       2. Display the current month's calendar, with Shabbat times, parshiot,  footnoted  holiday
          identification, with Hebrew information in Hebrew, and all in "calming", "muted" color-
          tones.

       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.
