XThis program accepts a year of the Jewish calendar, for example
X"5750", and produces on the screen a calendar of that year with a
Xvisually equivalent civil calendar opposite it for easy conversion of
Xdates. The months of the civil year are abbreviated to
X
XJAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
X
Xand of the Jewish calendar to
X
XNIS IYA SIV TAM AV ELU TIS HES KIS TEV SHE ADA AD2.
X
XMonths are normally displayed three at a time. You call up the next
Xthree by hitting return. At the end of the year you can indicate if
Xyou wish the program to conclude, by hitting return again. If in
Xresponse to the question, Do you wish to continue? you enter "y" and
Xhit return, the next year will be displayed.
X
XEach Jewish month has its name on the left. The corresponding secular
Xdates will have the name of the month on the right, and when the month
Xchanges it will be indicated on the right also.
X
XIf you wish, you may enter a civil year in the form -70 for BCE dates
Xand +70 for CE dates. The Jewish year beginning prior to Jan 1 of that
Xyear will be displayed, and you can continue with the next Jewish year
Xif you wish to complete the desired civil year.
X
XYou may enter CE or AD instead of + or BC or BCE instead of the minus
Xsign if you wish. It is best to avoid spaces, so enter 1987AD, for
Xexample.
X
XThe year 0 is not meaningful in either calendar. No date prior to 1
Xin the Jewish calendar should be entered. The program will calculate
Xany future year, but will take longer for years much beyond the year
X6020 in the Jewish reckoning. For example, the year 7000 will take
Xthree minutes or so to appear. Earlier years should appear in a few
Xseconds.
X
XA status line at the bottom of the screen indicates the civil and
XJewish year, and the number of days in each. Jewish years may contain
X354, 355, 356, 384, 385 or 386 days according to circumstances.
X
XWhen you are familiar with this program you can enter the years you
Xwish to see on the command line. For example, if you call the program
X
X iconx calendar 5704 +1987 1BC
X
Xyou will see in turn the Jewish year 5704, the Jewish year commencing
Xin 1986 and the Jewish year commencing in 2 B.C.E. You still have the
Xoption of seeing the years subsequent to these years if you wish. Just
Xenter "y" when asked if you want to continue. When you enter "n", you
Xwill get the next year of your list.
X
XAll civil dates are according to the Gregorian Calendar which first
Xcame into use in 1582 and was accepted in different places at
Xdifferent times. Prior to that date the Julian calendar was in use. At
Xthe present time the Julian calendar is 13 days behind the Gregorian
XCalendar, so that March 15 1917 in our reckoning is March 2 in the
XJulian Calendar. The following table shows the number of days that
Xmust be subtracted from the Gregorian date given here to find the Julian
Xdate. In the early centuries of this table and before the calendar was
Xintercalated erratically, so a simple subtraction is not possible. Note that
Xthe change in the number to subtract applies from March 1 in the century
Xyear, since in the Julian Calendar that will be February 29 except in years
Xdivisible by 400 which are leap years in the Gregorian calendar also.

XFor the bold in heart: Type in "cp Makefile.dist Makefile; make" and
Xwatch the sparks fly. When done, type "hebcalen." If you are satis-
Xfied that it works, exit, then su root, and then type "make install."
X
XThis archive contains a test Unix port of Alan Corre's Jewish/Civil
Xcalendar for MS-DOS. My changes to his code are extensive, and yet
Xmundane. Mainly I just rewrote the input/output routines so that they
Xwould be portable in a Unix environment, and would work with all the
Xnon-cookie terminals I have access to (e.g. VT100, ANSI, IBM 3101). In
Xparticular, I made sure to eliminate all assumptions about terminal
Xlength, width, and ability to display standout and/or underline modes.
XI also removed all characters which would require an unsigned internal
Xrepresentation (i.e. 8-bits).
X
XProbably the only really substantial changes I made were to add some
Xconvenient defaults. For instance, if you press CR at the
Xinstructions prompt, you'll move on automatically to the year prompt.
XIf you press CR at the year prompt, hebcalen assumes that you want the
Xcurrent civil year. Most of the prompts let you type "q" if you want
Xto quit at that point. Another added default is a search mechanism
Xfor data files. As long as the hebcalen data files are in your path,
Xyou no longer need to have them in the current directory when hebcalen
Xis invoked. These changes represent mere conveniences, and do not
Xalter the substance of the original distribution.
X
XFrom a packaging standpoint, the original calendar program has been
Xtotally redone. The original single file has been broken down into
Xits constituent parts, and renamed "hebcalen" so as to avoid naming
Xconflicts with tickler programs extant on many Unix systems. I've
Xalso added a Makefile to ease the pains of installation and
Xmaintenance. Just rename or copy Makefile.dist to Makefile, type
X"make," and then give the program a few trial runs. When satisfied it
Xworks fine, then type "make install." Make sure, before you do this,
Xthat you edit the makefile to reflect your local file structure.
X
XThe original distribution is included as cal.text. Please keep it
Xaround if you plan to do any hacking, or even perusal of the code.
XIt's a nice piece of work.
X
XMany, many thanks to Alan Corre for a well-written and useful contri-
Xbution to the Icon community's code pool.

X#COPYRIGHT (c) 1990
X#Permission is hereby given to all persons to copy, compile and pass to
X#others this code provided that (1) it is not used for monetary gain;
X#(2) it is not subverted from its original purpose, and is changed only
X#to the extent necessary to make it work on a different computer or terminal.
X#No guarantees are given or implied as to the correctness of information
X#furnished by this program.
X#Written in the beautiful Icon programming language. Further information from
X#icon-project at arizona.edu
X#If my math were longer this program would be shorter. Excuse me.
X#This work is respectfully devoted to the authors of two books consulted
X#with much profit: "A Guide to the Solar-Lunar Calendar" by B. Elihu Rothblatt
X#published by our sister Hebrew Dept. in Madison, Wis., and "Kiddush HaHodesh"
X#by Rabbenu Moses ben Maimon, on whom be peace.
X#The Jewish year harmonizes the solar and lunar cycle, using the 19-year cycle
X#of Meton (c. 432 BCE). It corrects so that certain dates shall not fall on
X#certain days for religious convenience. The Jewish year has six possible
X#lengths, 353,354,355,383,384,385 days, according to day and time of new
X#year lunation and position in Metonic cycle. Time figures from 6pm previous
X#night. The lunation of year 1 is calculated to be on a Monday (our Sunday
X#night) at ll:11:20pm. Our data table begins with a hypothetical year 0,
X#corresponding to 3762 B.C.E. Calculations in this program are figured in
X#the ancient Babylonian unit of halaqim "parts" of the hour = 1/1080 hour.
X#Version given here should work without change under MS-DOS. Hints are given
X#for modifying the code for other systems. Your MS-DOS should be sensitive to
X#ANSI screen controls. On many machines you may achieve this by having the
X#MS-DOS file ansi.sys available at boot time, and also a file called
X#config.sys which contains the statement DEVICE=ANSI.SYS Hints are offered
X#in case this is impossible.
X#Material consists of three sections separated by legend CUT HERE. This first
X#section should be placed in a file called calendar.icn. and compiled with
X#icont. Section two should be placed in a file called calendar.hlp.
X#The absence of this file will not impede the program. The information in
X#this file is unsuitable for the Macintosh. I can supply an alternate file.
X#Section three should be placed in a file called calendar.dat. This file is
X#essential, and must contain no extraneous matter at the beginning.
X#Program is run under MS.DOS by entering the command:
X# iconx calendar
X#which may optionally be followed by the years desired in the form 5750
X#for a Jewish year +1990 or 1990AD or 1990CE or -1990 or 1990BC or
X#1990BCE for a civil year. On some systems iconx can be omitted.
