Hebcal 1.3 - a program for printing Jewish calendars
  by Danny Sadinoff

DESCRIPTION
Hebcal is a program which prints out the days in the Jewish calendar
for a given gregorian year.  Hebcal is fairly flexible in terms of which
events in the Jewish calendar it displays.  Each of the following can
be individualy turned on or off:

  The Hebrew date
  Jewish Holdiays (including Yom Ha'atzmaut and Yom HaShoah etc.)
  The weekly Sedrah
  The day of the week
  The days of the Omer

CHANGES
  Fixed a critical bug which put Purim on the 15th of Adar, instead of
    the 14th
  Now uses sys/types.h instead of stdlib.h.  This will improve compatability
  Added the rest of the 8 days of Chanukah

DISTRIBUTION
This program is SHAREWARE.
It may be distributed freely, with a few conditions:
   1) The package must be distributed INTACT with ALL source code, as
   well as this file.  You are welcome to modify the code,
   but DON'T distribute it modified.  This disclaimer should certainly
   appear with every distributed copy.

   2) You can use this program for free for one week.  After that
   trial period, if you wish to use this program, drop me a line.
   I'd like to know who you are, how you're using hebcal, and any
   thing else you'd like to tell me.

   I am NOT demanding payment for the use of my program, but writing
   this program DID take time.  Feel free to send $10 to
   me at my US Mail address. (hint)

   send US Mail to:        send email to:
    Danny Sadinoff       [e-mail]
    1 Cove La.
    Great Neck, NY 11024

   Email respondents will receive notifications of new versions as they
   come out, as will US Mail responents (if they send me postage for a disk).

   If you do not mail me or email me after one week, please don't
   use the program, although you may feel free to distribute it further.

COMPILATION
The code has K&R "old style" declarations in it, so it should compile
on most machines.

The distribution includes a "Makefile" so once you've unpacked all the
files, just run the command "make" and that should compile everything
for you.

The file hebcal.l is the manual page.  For information on using man in
conjunction with local manpages, see the manpage for man.  Briefly, to
read a manpage in its original format, type
nroff -man <filename> | more

XDESCRIPTION
XHebcal is a program which prints out the days in the Jewish calendar
Xfor a given gregorian year.  Hebcal is fairly flexible in terms of which
Xevents in the Jewish calendar it displays.  Each of the following can
Xbe individualy turned on or off:
X
X  The Hebrew date
X  Jewish Holdiays (including Yom Ha'atzmaut and Yom HaShoah etc.)
X  The weekly Sedrah
X  The day of the week
X  The days of the Omer
X
XCHANGES
XSince version 1.1, the following changes were made:
X  Changed usage-- the -p "parshiot" switch was changed to "-s" sedrot switch
X  Fixed certain slippery variable type bugs
X  Changed code to K&R old style
X  Added Manpage
X  Decided to change the "Distribu-Ware" to a normal shareware.
X
XSince version 1.2:
X  Fixed a critical bug which put Purim on the 15th of Adar, instead of
X    the 14th
X  Now uses sys/types.h instead of stdlib.h
X  Added the rest of the 8 days of Chanukah

X
X
XOPERATION:
XThe operation of hebcal is fairly simple.  Hebcal defaults to printing
Xout the holidays for the current gregorian year.  With the
Xcommand-line options, a specific gregorian year, month or date can be
Xspecified.
X
XGiven one numeric argument, hebcal will print out the calendar
Xfor that year.  Given two numeric argumetnts mm yyyy, it
Xprints out the calendar for month mm of year yyyy.  Given three
Xnumeric arguments mm dd yyyy, it will print out the hebrew calendar
Xentries for day dd of month mm of year yyyy.  In the last case, the -d
Xoption is automatically enabled.
X
XBe sure to give the whole year to hebcal.
Xhebcal 92 will return the calendar for a time somewhere in the early
Xchristian era, not in the twentieth century.  Use hebcal 1992 instead.
X
Xusage: hebcal [-dehostTw] [[month [day]] year]
X       hebcal help --- prints this message.
X
XOPTIONS:
X   -d : add hebrew dates
X   -e : use European dates (dd mm yyyy) for OUTPUT ONLY (input format
X        the same)
X   -h : suppress holidays
X   -o : add days of the omer
X   -s : add weekly sedrot
X   -t : only output today's date.  This switch implies the -d switch.
X   -T : only output today's date, suppressing gregorian date. This
X        switch implies the -d and -o switches.
X   -w : add day of the week
X
X
XExamples:
Xexample% hebcal -ho
X4/19/1992 1st day of the Omer
X4/20/1992 2nd day of the Omer
X4/21/1992 3rd day of the Omer
X4/22/1992 4th day of the Omer
X4/23/1992 5th day of the Omer
X4/24/1992 6th day of the Omer
X.
X.
X6/5/1992 48th day of the Omer
X6/6/1992 49th day of the Omer
X
Xto print out all of the data pertaining to today's date, use
X
Xexample% hebcal -otw
X10/26/1992 Mon, 29 of Tishrei, 5753
X
Xto find out what's happening in today's Jewish calendar, use
X
Xexample% hebcal -T
X19 of Nisan, 5752
XPesach V (CH"M)
X4th day of the Omer
X
X
XDISCLAIMER
XI tried to make this program as accurate as possible.  However, I
Xtake no responsibility for any horrible consequences which may come
Xabout as a result of faulty output from this program.  Remember: never
Xtrust a program with a zero at the end of its revision number.
X
XThe secular dates before september 1752 are off by two weeks due to
Xthe correction that took place then.
X
XThe secular dates before 1522 become progressively meaningless, as I
Xmade no correction for the changeover from julian to gregorian
Xcalendars; but the Hebrew dates and years are correct.
X
XCOMING SOON
XFeatures to be included in future versions:
X  - need to add Yom Yerushalayim
X  - Arba' parshiot
X  - The ability to specify and output a particular HEBREW year, month
X    or date.   The absence of this feature is a serious drawback to
X    hebcal as it now stands.
X  - calendar-like operation with user specified "holidays",
X       e.g. birthdays, yahrtzeits.
X  - yahrtzeit lists: calculate a list of dates in successive gregorian
X       years with the same Hebrew date.

X.SH NAME
Xhebcal - a Jewish calendar generator
X.SH SYNOPSIS
X.B hebcal
X[
X\-dehostTw
X] [[
X.I month
X[
X.I day
X]]
X.I year
X]
X.br
X.B hebcal help
X.SH DESCRIPTION
XWith no arguments,
X.B hebcal
Xwill print to stdout the
Xdates of the Jewish holidays in the current
Xsecular year.  Each line is prefixed with a gregorian date of the form
Xmm/dd/yy.
X.sp
XBy specifying
X.I month,
X.I day,
Xor
X.I year
Xoutput can be limited to a particular month or date
Xin a particular year.
X.sp
X.I year
Xis an integer (it can be negative).  So 92 is in the early Christian
Xera, not the late twentieth century.
X.sp
X.I month
Xis a number from 1..12.
X.sp
X.I day
Xis a number from 1..31.
X.sp
XFor example, the command
X.nf
X
X    hebcal 10 1992
X
X.fi
Xwill print out the holidays occurring in October of 1992.
X.PP
XA few other bells and whistles include the weekly
X.I sedrah
Xas well as the day of the week, the count of the
X.I omer,
Xand the Hebrew date.
X.PP
XOutput from hebcal can be used to drive calendar(1).
XDay\-to\-day use for hebcal is provided for in the
X.B -T
X and
X.B -t
Xswitches, which print out Jewish calendar entries for the current date.
X.PP
X.SH OPTIONS
X.TP 1.0i
X.B "  -d"
XAdd the Hebrew date to the output.
X.TP
X.B "  -e"
XChange the output format to European-style dates: dd/mm/yyyy
X.TP
X.B "  -h"
XSupress holidays in output.
X.TP
X.B "  -o"
XAdd the count of the
X.I omer
Xto the output.
X.TP
X.B "  -s"
XAdd the weekly sedra to the output.
X.TP
X.B "  -t"
XPrint calendar entry for today's date only.  -d is asserted with this option.
X.TP
X.B "  -T"
XSame as -t, only without the gregorian date.  This option is useful in
Xlogin scripts, just to see what's happening today in the Jewish calendar.
X.TP
X.B "  -w"
XAdd the day of the week to the output.

X.SH SEE ALSO
Xcalendar(1), hcal(1), hdate(1), omer(1), rise(1)
X.sp
XThe motivation for the algorithms in this program is the
X.I "Tur Shulchan Aruch.  "
XA well written treatment of the Jewish calendar is given in
X.I Understanding the Jewish Calendar
Xby Rabbi Nathan Bushwick.  A more complete bibliography on the topic
Xcan be found there.
X.SH BUGS
XThere are some omissions from the list of included holidays, including
X;Yom Yerushalayim.
X.sp
XRight now, hebcal dosn't perform enough sanity checking on input
Xdates.
X.sp
XHebcal performs no checking for changes between the julian and
Xgregorian calendar, so secular dates before 1752 are untrustworthy.
X.sp
XHebcal cannot currently handle date computations before 2 C.E.  sorry.
