Perfection! The alternative 3840-year cycle



Step 3: Roman (Julian) year of 365.25 days: 

Main Cycle:
(Forty-year cycles)

The 365-day year lags behind the more accurate 365.25 year by one day every four years. (365.25 less 365 = .25, or a quarter of a day. Therefore, in 4 years one whole day accumulates since four quarters of a day equals one whole day.) To correct this problem, Julius Caesar ordered that upon every fourth year a 'leap day' be added to their 365-day year. This average year of 365.25 days was introduced about 45 BC, but God delayed its consistent use until about the birth of Jesus Christ as a sign that "the fullness of time" had come, Gal. 4:4. (Here is a good site about the origins of the Julian calendar.) 

We still use an updated version of the Julian calendar today.  


The amount of days in a Julian year calculated

365 days x 4 years = 1460 days, + 1 leap day = 1461 days. 

1461 divided by 4 years = 365.25 days in a Julian year

The 365.25 day-year is also the accuracy level of the main cycle of the 360-prophetic calendar.


--- 40-year cycles form the core of the prophetic calendar ---

We have already stated that upon every 6 years, one month of 30 days are accumulated so that the 6th year has 390 days in it. This works out to an even 365 day-year. However, to increase the accuracy level to 365.25 of the Julian calendar we must do the following:



To attain to the Egyptian level of accuracy of 365 days in a year, the prophetic calendar utilizes 6-year cycles, (12 months in a year, 30 days in a month = 360 days in a year,  with the sixth year having 13 months [ 390 days], a grand total of 2190 days every 6 years.)

To attain to the more accurate Roman (Julian-calendar) level of 365.25, this is what we must do:

40-year Cycles

The 6th cycle of 6 years is followed by a 7th cycle only 4 years long---for a total of 40 years, (a " generation" in the bible). (6 x 6 = 36 years, + 4 years = 40 years.)

These numbers agree with the creation model of a 6 day-creation, 
with the 7th day set apart as special, (Gen. 1-2). 



The 40-year Cycle of the 360 Prophetic Calendar

1st leap-month

2nd leap-month

3rd leap-month

4th leap-month

5th leap-month

6th leap-month

7th leap-month

at end of 6-years







2,190 days

2,190 days

2,190 days

2,190 days

2,190 days

2,190 days

1,470 days

= 40 years with 14,610 days = 365.25 days x 40 years 


Thus, the 6th cycle of 6 years is followed by a 7th cycle only 4 years long---for a total of 40 years, (a "generation" in the bible). (6 x 6 = 36 years, + 4 years = 40 years.) The effect is to place emphasis upon the 6th and 7th cycle since the 6th cycle of 6 years precedes the special seventh cycle of only 4 years, which in turn concludes the 40-year cycle. 



This concludes the first three of seven 'steps.' The 40-year cycle is foundational to the prophetic calendar. These 3 'steps' increased in accuracy from a simple 360-day average year to a 365, and then to a 365.25. You will find that the rhyme and reason for 90% of time-related numbers in the bible are resolved by applying this calendar to your study. The remaining 10% are illumined by the last 4 'steps' of increased accuracy. Fortunately, the remaining steps are even more easy to learn.

A Few Technical Notes:

1. New-years day of Nisan (Abib) 1st (morning) of the 360 calendar landed on April 9, 1446 BC (Gregorian calendar, but which was April 22 Julian). (April 9th on the conventional Jewish calendar that year was about Nisan 11.) The Julian day # is 1193382. (That day, therefore, symbolized as AD 1 as explained later.)  (Note: after writing this is was realized that 30 days earlier, that is, March 10, 1446 BC, is the primary date for when the New Year began even though April 9th is indeed aligned with the the Creation. Please see, "How to find any date on the 360-calendar" for details and important table of dates explained.)

2. The 4000-year cycles began in 4006 BC at the Creation and again when they entered Egypt in 1446 BC. (Nisan 1 on the 360 calendar in 4006 BC falls on, or about, the spring equinox, March 21 Gregorian, which is April 22 Julian, which happens to be Nisan 1 on the regular Jewish calendar {as well as the 360 calendar}, which makes it a new moon! {Julian #258342.} The new moon, the spring equinox, and the start of the 360 calendar are therefore perfectly aligned with this Creation date to signal 'a new beginning'. However, it is my personal view that this date is merely symbolic for the Creation, and that the actual Creation date may be something else.)  

Note that both Creation ( 4006 BC) and the Exodus (1446 BC, see note #1) run along the same 40-year cycles.

The first 4000-year cycle ends at about the time of the conception of John the Baptist and Jesus Christ in 6 BC, (Julian #1719312, March 21 Gregorian, 23rd Julian). There are 64 generations/cycles of 40 years that pass between the Creation and the Exodus, and once again, 64 is a square-root figure, that is, 8 x 8, (or 8 x 8 x 8 x 5 years = 2560 years). Fittingly, the number "eight" in the bible symbolizes "a new beginning", with 2560 years being about how many days there are in a seven-year period, hence memorializing the Creation that took place in "seven days" --- a year for each day.

Observe that an overlap of one month (30 days), therefore, occurs between the years 6 BC and AD 2555 (2560 years). This is because the 4000-calendar from the Exodus will not complete its first cycle until AD 2555 thereby being ahead of the Creation-calendar by one leap-month all during this 2560-year span. This means that currently, and for the next 560 years, there is a one-month gap between the two calendars. 

The creation date is not based upon biblical chronology, although it is certainly in the right ballpark. The creation date of 4006 BC is mainly based upon the deduction that a calendar from creation should both weave into the time of the exodus and the birth of Christ, and this one does both exceedingly well. However, the exodus date is the only calendar date that is clearly established by the bible itself. The creation date is only inferred, although strongly so. For more about this, and why the exodus date, see, "What Year are We in According to the 360 Calendar?"

Concerning the 3840-year cycles, I have come to favor the 4000-year cycles for its simplicity over the 3840-cycles, and simplicity is important for a calendar. After that are the 100,000-year cycles. Thus, 40 and 4000 and 100,000-year cycles. Beyond that I may have gone too far. I may yet put all other information on this website in archive. I am not as convinced of the 3840 cycles as I once was. It works just like I said, but it lacks simplicity, something I underestimated for significance. Also, when the calendar gets into cycles that run into the trillions of years, the symmetry exhibited might largely be due to the quirks of numbers. Numbers can do strange things by their very nature! See, "What Year are We in According to the 360 Calendar?"
