 Seven Simple Steps
Step 3

 

 

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:

 

Review:

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).

40 years of 14,610 days

 

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. 

 

Conclusion:

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.
