364-days: The Calendar of Reconcilliation
The Book of Enoch, the Book of Jubilees, other extra-biblical literature of that time period, and to a lesser extent, the Bible, all utilize a year of 364-days.
But why 364?
It’s because 364 is divisible by weeks (seven), as well as its four seasons (91 x 4 = 364). It’s the Calendar of Reconciliation because it reconciles “seven” (the number for perfection) and “13” (the number for rebellion and failure), (7 x 13 = 91). And this reconciliation is universal, which is what 4, 40, 400, etc., symbolizes, as in “the four corners of the earth”, (4 x 13 x 7 = 364).
However, 364 is short of an exact (but slowly decreasing) solar year of 365.24218967.
And so, the question arises: How do we reconcile 364 with a true solar year of 365.2425?
What is the best method of doing this without disturbing the integrity of unending cycles of perfection (weeks)?
This is the holy grail of most cultures from time immemorial — reconciling 4, 7, and 13 in a presumed orderly universe.
Hopeless you say?
There are Two Fundamental Methods of Calendar Intercalation:
The year is scrutinized every spring (non-mechanized)’ and the other, ‘Adjustments are worked out many years ahead of time (mechanized)’
Different people groups, including Jews, throughout ages, add leap months to their lunar calendars when it lags behind the Spring Equinox by more than a month (or some other similar methodology). This is the ‘non-mechanized’ method. It works best for non-dispersed, united people.
However, other people groups, such as the Babylonians and post-exilic Jews utilize a mechanized approach, valid no matter where one lives on earth. Both mechanized and non-mechanized methods usually have the same outcome.
In the same way as the lunar calendar, the Enochian Calendar is adjusted to the true solar year using either method.
Therefore, there are two ways of calculating leap weeks for the Enochian Calendar:
1. (Non-mechanized) A decision is made every spring
A leap week is added when the 364-day year lags behind the Spring Equinox by more than a week. This is a valid method and works well for non-dispersed, united people.
2. (Mechanized) A method is devised for all time
The remainder of this post explains the two best methods (mechanized) of intercalating leap weeks for all time: The Shmita/Jubilee method and the 40-year generational method.
Both are compatible. There are other methods. But after much study, these two are the best and the ones most likely reflected in the Bible and other extra-biblical literature.
Keep in mind that our goal is not to create calendars to live by.
Please no!
Our purpose is to analyze patterns produced by the 364-Calendar that gave rise to the symbolic meaning of numbers in the Bible.
Footnote: The Essenes (of the Dead Sea Scrolls) likely used one of these two methods, but we cannot be sure. However, in this study, we care little about what the Essenes practiced, but rather what the Bible, the Book of Enoch and the Book of Jubilees say or imply.
The Shmita/Jubilee Method
A Shmita is a seven-year period of rest commanded upon the land in the Bible. The Jubilee is seven Shmitas, for a total of 49 years. Thus, in 490 years there are ten jubilees.

Add a leap week every seven years (2548 + 7 days).
Every jubilee, add 3 weeks — with the exception of 3 out of every ten jubilees (490), where just 2 weeks are added. Thus, 490 years has 178969 days, (an average year of 365.2428571 days).
490 Gregorian years is also 178969 days. Thus, seven of Daniel’s “70 weeks” have 2569 days, and 2569 is also 7 lunar years. 2569 is also ‘1260 + 1260 + 49′ and links the 49 days to Pentecost, John 20:22. Moreover, “1260” (Rev. 12:6) in conjunction with 1274 (with optional 1 to 3 leap weeks) is immensely compatible with the week of Passover and Tabernacles. Each lasts 7 days and begins 7 days after the 7 days of Creation (1st & 7th month, 15th to 21st day incl.). Dan. 10:1-4 simply divides the week’, Dan. 9:27.
Moreover, 490 x 360 (176400) plus “2569” equals “178969 days” and “176400” is 525 priestly cycles, (336 x 525). This demonstrates the harmony between the 336, 360, 364, 365, and 365.2425-day year — as well as a lunar and 361-day year.
Compare all the above to Dan. 9:24-10:4.
The 364-Cal. Jubilee New Year begins 1406 BC, Wed., Julian day #1207977.75 unto #2460760.75 in AD 2025. “3”, “7” & “10” are all numbers that symbolize completion.
The final 210th (3 x 7 x 10) Jubilee year (10290 years) has just 378 days, (mean ≈365.242177). See 1406 BC & 10290 x 3 to Pillar. Compare with Enoch Chart.
Footnote: 2025-2032 AD is 7 x 490 from the Conquest of Canaan (1406-1399 BC), and 7 x 364 (plus 2 or 3 weeks of years) from 538 BC, (the return to Promised Land). Ponder that!

The 364-day year and cycles of 40 and 400 years
We just explained the Jubilee Method of regulating the 364-day year. We now discuss the simpler, alternative method.
Remember 2012 and the end of the world scare with the Mayan calendar? The Mayan calendar ended its 13th cycle on Dec. 21st, 2012. Each cycle has 144,000 days, (that is 360 x 400 days). I posted the calendar converter at that time, which emphasized the 360-calendar. Let us now add to this the Enoch calendar of 364 days. It is structured the same as the 360-calendar.
The Book of Enoch informs us that the 364 and 360-day years are really one and the same, (Enoch 75:1). This is further evident when the two below tables are compared. The two calendars are highly compatible due to their 4-day difference. Observe the repetition of 4, 40, 400, and 4000 in these calendars.
Eight methods were posted last year as to how the Enoch calendar can be intercalated. Each was ascribed to one of the eight angels of the Book of Enoch in keeping with the spirit of that book. However, this new method of intercalation is for men, at least that's the way I personally designate it. It was discovered Sept. 22-23, 2020, although David Rooke and myself pondered a solution similar to this two years ago.
Please see the end of this post for specifics on the Julian day year in 6 BC for the New Year on Enoch's 364-day calendar.
Observe below how the 7th cycle is distinguished from the previous six cycles. (It’s the same pattern as at Creation when God worked six days but rested on the 7th.)
40-Year Cycle of 360-day year
1st leap-mth | 2nd leap-mth | 3rd leap-mth | 4th leap-mth | 5th leap-mth | 6th leap-mth | 7th leap-mth |
6 years | 6 years | 6 years | 6 years | 6 years | 6 years | 4 years |
2190 days | 2190 days | 2190 days | 2190 days | 2190 days | 2190 days | 1470 days |
But 7th leap-month of 100th 40-year cycle (4000 years) has 1440 days |

6 years | 6 years | 6 years | 6 years | 6 years | 6 years | 4 years |
2191 days | 2191 days | 2191 days | 2191 days | 2191 days | 2191 days | 1463 days |
But 7th leap-month of 10th 40-year cycle (400 years) has 1470 days |
- Both are as accurate as our Gregorian year of 365.2425 days
- The 360-cal after 40 years is the same as the Julian year
A “leap month” is 30 days on the 360-calendar. A “leap week” on the Enoch calendar, of course, is seven days. Thus, seven leap months/weeks are inserted (intercalated) within each 40-year cycle. This is similar to the seven leap months of the Metonic 19-year cycle of the lunar calendar observed by Jews today. Seven is the number of days of Creation.
One can easily see why the Gregorian year of 365.2425 can use the same pattern of creation of seven intercalations within a 40-year cycle employing leap months of 30 days, and also leap weeks of seven days, (and even leap days as with our modern method). It’s because the numbers three, seven, and four dominate the equation for a solar year.
“In the beginning” the year was 365.2425 days
About 4000 BC when God created the sun and moon according to a literal interpretation of the Bible, the actual solar year was indeed about 365.2425. The below formula for the Gregorian year of 365.2425 as used in our calculations is both accurate and elegant — something one would expect from God who created the sun and moon on the fourth day, that is, ‘in the middle of the week’ (seven).






As explained before, when 13 and seven come together in some way it signifies the ‘undoing or reversing the curse (13)’. Example: 13 x 7 x 4 seasons equals the 364 days of the Enoch cal. Now add the outer three branches as it moves towards the center. 13 + 7 + 13 = 33, (or even, 40, due to the overlap of the middle seven).
A burning bush -- The Perfect Trinity? 3 x 3 x 3 x 7 x 773 = 146097 days. Just for fun, total the mean of the 16 prime factors of 146097. It's '6 x 6 x 430'. See Gen. 15:13 and Ex. 12:40. Add each digit in 146097 together: Equals 27, that is, 3 x 3 x 3. Recall the meaning of 7 and 13 together. Add the digits of 365 and its remainder.2425, They equal 14 {7 x 2} and 13 for total again of 27 {3 x 3 x 3).
The earth, sun, and moon are round — so if you were God, why not have the formula for a circle, “π”, encoded in the length of the year?


As compared to our Gregorian Calendar
The Gregorian calendar is what is used throughout most of the world, including the United States.
- We add a leap day is added every four years
- Every 400 years also has a leap day, but the other three centuries do not
- This produces an average solar year of 365.2425, the same as the 360 and 364-Enoch calendars
General observations
- Notice the reoccurrence of cycles 4, 40, 400, and 4000 within all calendar systems. This explains why this number is so frequent in the Bible — because God created the sun and moon on the 4th day, Gen. 1:14-19
- Observe that the last 4 years of the 40-year cycle of both the 360-calendar and the Enoch have “1470 days” (49 x 30) after 400 years
- It’s the four-day difference between 360 days (12 months) and 364 days (52 weeks) that create this harmony
- Perfect solar eclipses, unique to our planet, is possible because the sun is 400 times further away from earth than the moon, but the sun is 400 times larger than the moon so that the apparent size to our eyes remains the same
- Observe that every 40 years, 7 x 7 days are added on the Enoch calendar, a ‘perfect’ number. Therefore, when the extra week is added after 400 years, then 490 days accumulate, that is, “70 weeks” add one.
- Or viewed as “7 weeks + 62 weeks plus one week {+ 7}, at the end of the “400 years in Egypt”, cf., Daniel 9:24-27
- Even the Mayan calendar is made up of cycles of 400 x 360 days (144,000, “baktun”) — although divided as 7200 x 20
The lunar calendar is well suited to this pattern as well. However, instead of 400 years, there are 399 (7 x 3 x 19). This means that every ’40 x 40 years’ (less four) all calendars overlap.
We explain the lunar connection next.

Two intersecting 400-year periods on the Enoch calendar
Details about Enoch calendar
There are two intersecting 364-day calendars: The first began at Creation and seven cycles of 400 years later are when Israel entered the Promised Land in the spring of 1406 BC. Creation from this perspective was 4206 BC, (very close to the Samaritan Pentateuch Creation date of 4200 BC).

Enoch’s 364-calendar begins at the Julian day of #1719320. (I.e., 6 BC, Wednesday 6 AM {Julian March 31st, Greg. March 29th}, which was Nisan 11th on the lunar calendar that year. Its next 400-year cycle is in 400 years. (Note: the cal. converter incorrectly reads Nisan 12th for this day, due to the accumulative error this far back in time with the Metonic cycle.)
.
However, from the perspective of 1406 BC (Julian #1207977, i.e., March 25th Gregorian), exactly 511336 days later the New Year fell one week earlier on Julian #1719313. (#1719313 is 6 BC, Wednesday 6 AM {Julian March 24th, Greg. March 22nd}, which was Nisan 4th –that is, the anniversary of the 4th day of creation when the sun and moon were created as per the lunar calendar, Gen. 1:14-19). Its next 400-year cycle is in 200 years. (The cal. converter incorrectly reads Nisan 5th for this day, due to the accumulative error this far back in time with the Metonic cycle.)

- For a detailed Excel spreadsheet by David Rooke including notes, click here:(1900-2100 AD).
It is easy to work out the date of the New Year on the Enoch calendar because 400-years on the Enoch calendar is the same as 400-year on our Gregorian calendar. See the Calendar Converter.
Observations:
Therefore, from 206 to 406 AD the two parallel 400-year cycles synchronize, that is the New Year and all festivals fall on the same day. This means that all the sections on the chart that are not colored in beige have the same dates. This also means that for 200 years prior to 1995 AD the New Year harmonized, but for 200 years after 1995, (1995 became March 22nd and 29th), the New Year is one week apart. For example, both the mornings of Sept. 16th and Sept. 23rd (Wednesday) began the seventh month (Feast of Trumpets) on the Enoch calendar.
"Coincidentally", the revelation about the 400 -year cycle on the 364-calendar was also revealed the morning of Sept. 23rd, 2020. Moreover, the New Year on the 360 calendar began 3.5 days earlier, which runs evening to evening, thereby dividing the week in half. Also, 400 years earlier to the very day the Mayflower set sail for the New World. Consider the astounding Signs on the Feast of Trumpets/Rosh Hashannah, 2020.


Alternative intercalation of the 364-days
The Alternative Jubilee Method
Every 7 years add a leap week (2548 + 7 days).
Every jubilee add 3 weeks -- with the exception of 3 out of every ten jubilees (490), where just 2 weeks are added. Thus, 490 years has 178969 days, (an average year of 365.2428571 days).
490 Gregorian years is also 178969 days. Thus, seven of Daniel's "70 weeks" have 2569 days, and 2569 is also 7 lunar years. 2569 is also '1260 + 1260 + 49' and links the 49 days to Pentecost, John 20:22. Moreover, "1260" (Rev. 12:6) in conjunction with 1274 (with optional 1 to 3 leap weeks) is immensely compatible with the week of Passover and Tabernacles. Each lasts 7 days and begins 7 days after the 7 days of Creation (1st & 7th month, 15th to 21st day incl.). Dan. 10:1-4 simply divides the week', Dan. 9:27.
Moreover, 490 x 360 (176400) plus "2569" equals "178969 days" and "176400" is 525 priestly cyles, (336 x 525). This demonstrates the harmony between the 336, 360, 364, 365 and 365.2425-day year -- as well as a lunar and 361-day year.
Compare all the above to Dan. 9:24-10:4.
The 364-Cal. Jubilee New Year begins 1406 BC, Wed., Julian day #1207977.75 unto #2460760.75 in AD 2025. "3", "7" & "10" are all numbers that symbolize completion, as can "400".
At the end of 400 jubilees a leap week is dropped, producing a Gregorian & 360-Cal. average of 365.2425 in 19600 years. 2025-2032 AD is 7 x 490 from the Conquest of Canaan (1406-1399 BC), and 7 x 364 (plus 2 or 3 weeks of years) from 538 BC, (the return to Promised Land). Ponder that!
