After all of the work on the "Prophetic Calendar" I realized that the "Prophetic Calendar" does not coincide with any modern day calendar. I began to be curious as to how the prophetic dates of Daniel would fit with the Modern Jewish calendar. We must first realize that the Modern Jewish calendar is not the same calendar Daniel was familiar with since a number of revisions in the calendar have taken place through the years {Just as changes have been made in the Julian/Gregorian calendar since the days of Jesus}. Daniel could not have forseen the Modern Jewish calendar, and could not understand how the dates he was given might fit together on a calendar which would be in use about 2500 years in his future. However, the reference to the antichrist's desire to change "times" {calendars} {Dan. 7:25} in the future suggests that the antichrist will realize the importance of a calendar {in particular the Jewish calendar} in use during his lifetime and will deliberatly change the calendar to turn attention away from the prophecies of Daniel and the Revelation.

The following gives the setup of the Modern Jewish calendar:

 ** Jewish Calendar - Modern **
MONTH 1 -- Tishri - 30 days {Sept/Oct}
MONTH 2 -- Heshvan - 29 or 30 days {Oct/Nov}
MONTH 3 -- Kislev - 30 or 29 days {Nov/Dec}
MONTH 4 -- Tebeth - 29 days {Dec/Jan}
MONTH 5 -- Shebat - 30 days {Jan/Feb}
MONTH 6 -- Adar - 29 or 30 days {Feb/Mar}
MONTH 7 -- Adar II (leap year only) - 29 days
MONTH 8 -- Nisan - 30 days {Mar/Apr}
MONTH 9 -- Iyar - 29 days {Apr/May}
MONTH 10 -- Sivan - 30 days {May/June}
MONTH 11 -- Tammuz - 29 days {June/July}
MONTH 12 -- Ab - 30 days {July/Aug}
MONTH 13 -- Ellul - 29 days {Aug/Sept}

** Jewish Calendar - {The Lord's Calendar for the Jews} **
{As set in Exodus 12:2 and Leviticus 25}
MONTH 1 -- Nisan {March/April}
MONTH 2 -- Iyar {April/May}
MONTH 3 -- Sivan {May/June}
MONTH 4 -- Tammuz {June/July}
MONTH 5 -- Ab {July/Aug.}
MONTH 6 -- Ellul {Aug./Sep.}
MONTH 7 -- Tishri {Sep./Oct.}[Rosh Hashanah, Feast of Trumpets,Day of Atonement {Yom Kippur},Feast of Tabernacles]
MONTH 8 -- Heshvan {Oct/Nov}[Passover, Easter]
MONTH 9 -- Kislev {Nov/Dec}
MONTH 10 -- Tebeth {Dec/Jan} [Pentecost {Feast of Weeks}]
MONTH 11 -- Shebat {Jan/Feb}
MONTH 12 -- Adar {Feb/Mar}
MONTH 13 -- Adar II

We call the bottom calendar the "Old" Jewish calendar. In reality, the "New" or "Modern" Jewish calendar at the top is supposedly the older calendar! The first month of the year supposedly originally began in September/October, but was changed by the Lord's command in Exodus 12:2 to the month of Nisan in March/April {the month of the Passover}. Modern Jews have reverted back to the old calendar and have also changed the Passover from the evening of the 14th of Nisan to the evening of the 15th. Many believe these changes were intended to draw attention away from the crucifixion of Jesus and His fulfillment of prophecy.

While at chaplain school, a Jewish rabbi told me that the Jews are the only people who celebrate the new year {Rosh Hashanah} during the SEVENTH month rather than the FIRST month. I believe there are prophetic reasons why this is true! {Possibly because this is time of the year Armageddon will take place, and possibly the Rapture. I am not 100% sold on the idea that the rapture will be at Rosh Hashanah, but I do not have enough Biblical evidence to conclude that this is a wrong interpretation.}

Rules for construction of the Modern Jewish calendar:
{Note: The Jewish day begins at 6:00 p.m., not 12:00 a.m. as on the Gregorian calendar.}

Tishri will always begin in September or October.
Nisan will always begin in March or April.
Tishri 1 must occur on the new moon {which must be calculated to the nearest minute based on Jerusalem time} with the following exceptions:
   When it occurs on a Sunday, Wednesday, or Friday, it is postponed to the following day.
   When the new moon occurs at noon or later Tishri is postponed to the next day (and to the
        following day if this would cause it to land on Sunday, Wednesday, or Friday).
   When it occurs on a common year succeeding a leap year, and after 9 a.m. it is postponed to
       the following day.

Based on the above rules, Rosh Hashanah will actually not fall on the true new moon but will be postponed to the following day more than 60% of the time!

The Jewish calendar follows the "Golden Cycle" based on the 19 year solar cycle. {The "Golden Cycle" is the number of years it take for the lunar months to re-align with the solar years -- 19 solar years equals approximately 235 lunar months -- 6939.689621913 days} The following years in the cycle are "leap" years: 3, 6, 8, 11, 14, 17, and 19th years. These years have thirteen months. The thirteenth month is call ADAR II on the Jewish calendar. Common years may have 353 days, 354 days, or 355 days. Leap years have 383 days, 384 days, or 385 days. To determine the length of the year, you must calculate when the next Rosh Hoshanah New Moon will occur, determine if Rosh Hoshanah must be postponed due to the above rules, and you must know whether it is a leap year or not. Then based on these rules, the months of Heshvan, Kislev, and Adar are adjusted to fulfill the requirements as follows:

Length of regular year:

353 days -- 12 months, alternately having 30 and 29 days, except Kislev has 29 days
                    instead of 30 days
354 days -- 12 months, alternately having 30 and 29 days
355 days -- 12 months, alternately having 30 and 29 days, except Heshvan, with 30
                   days instead of 29

Length of leap year:

383 days -- 12 months, alternately having 30 and 29 days, except Kislev has 29
                   days instead of 30 days, with 1 additional month, Adar I will have 30 days
384 days -- 12 months, alternately having 30 and 29 days, with 1 additional month,
                   Adar I will have 30 days
385 days -- 12 months, alternately having 30 and 29 days, except Heshvan with
                   30 days instead of 29 days, and one additional month, Adar I will have 30 days

Rosh Hashanah, Tishri 1, 5757, {Sept. 14, 1996} is the beginning of the 19th year in the leap year cycle and is therefore a leap year. To determine whether a year is a leap year, divide the year by 19; the remainder is the year in the cycle. {The year 5757 divided by 19 yields 303 with a remainder of 0 which means it is the 19th year in the cycle.}

The exact New Moon is computed from observatory data which yields 29.530588437 days from New Moon to New Moon. {29 days 12 hr 44 min 2.841 sec} The exact rules for calendar construction are given in Arthur Spier's book: The Comprehensive Hebrew Calendar, Feldheim Publishers, 1981, New York and Jerusalem  [ISBN# 0-87306-288-4].

For anyone interested, I have written a computer program {available upon request} which will calculate the Jewish calendar months using the astronomical star date calendar for any year past, present, or future and will give the reference dates for certain holy days. This information is given for the years 1947 A.D. - 2050 A.D.

The Reference Date given with the calendar dates uses Friday, Iyar 5, 5708  C.E. {May 14, 1948} as reference date - 0 and computes all dates relative to this date. By doing this anyone can quickly determine the number of days between any two Jewish holy days by simple subtraction.
