The months of the civil year are abbreviated to + +JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC + +and of the Jewish calendar to + +NIS IYA SIV TAM AV ELU TIS HES KIS TEV SHE ADA AD2. + +Months are normally displayed three at a time. You call up the next +three by hitting the space bar (or any other character). You may +conclude at this point if you wish by clicking on the word "Run" at +the top of the screen, dragging down to "Stop" and releasing. +At the end of the year you can indicate if you wish to +view the next following year by entering the letter "y" in response to +the question, Do you wish to continue? If you enter "n" the program +will conclude, or go on to the next year you wished to see if you +called the program with multiple entries of years. (See below.) + +Each Jewish month has its name on the left. The corresponding secular +dates will have the name of the month on the right, and when the month +changes it will be indicated on the right also. + +If you wish, you may enter a civil year in the form -70 for BCE dates +and +70 for CE dates. The Jewish year beginning prior to Jan 1 of that +year will be displayed, and you can continue with the next Jewish year +if you wish to complete the desired civil year. + +You may enter CE or AD instead of +, or BC or BCE instead of the minus +sign if you wish. Avoid spaces, so enter 1987AD, for example. + +The year 0 is not meaningful in either calendar. No date prior to 1 +in the Jewish calendar should be entered. The program will calculate +any future year, but will take longer for years much beyond the year +6020 in the Jewish reckoning. For example, the year 7000 will take +three minutes or so to appear. Earlier years should appear in a few +seconds. + +A status line at the bottom of the screen indicates the civil and +Jewish year, and the number of days in each. Jewish years may contain +354, 355, 356, 384, 385 or 386 days according to circumstances. + +When you are familiar with this program you can enter any number of years +you wish to see. Before you start the program, click on "Options", drag +to "Parameter String" and release. You can then enter, for example + 5704 +1987 1BC +then click on the box marked "OK". If you want to change these later, go +back to "Options" and type in your new list. You will see in turn the +Jewish year 5704, the Jewish year commencing in 1986 and the Jewish year +commencing in 2 B.C.E. You still have the option of seeing the years +subsequent to these years if you wish. Just enter "y" when asked if you +want to continue. When you enter "n", you will get the next year of your +original list. + +When you are completely through with the program, click on "File" at +the top of the screen, drag to "Quit" and release. If you wish you can +drag to "Transfer" and you will see a dialogue box to transfer to another +program, or to Hypercard. + +All civil dates are according to the Gregorian Calendar which first +came into use in 1582 and was accepted in different places at +different times. Prior to that date the Julian calendar was in use. At +the present time the Julian calendar is 13 days behind the Gregorian +Calendar, so that January 20 1990 in our reckoning is January 7 in the +Julian Calendar. The following table shows the number of days that +must be subtracted from the Gregorian date given here to find the Julian +date. In the centuries before the current era the calendar was +intercalated erratically, so a simple subtraction is not possible. + +Century # to subtract Century # to subtract + 21 13 11 6 + 20 13 10 5 + 19 12 9 4 + 18 11 8 4 + 17 10 7 3 + 16 10 6 2 + 15 9 5 1 + 14 8 4 1 + 13 7 3 0 + 12 7 2 -1 + 1 -2 + |
