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.

*  Erev Yom Kippur

~  Hol HaMoed

!  Hanuka and Purim

#  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

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.
