Key Points from Seeking an Actual Date for the Flood:
Choosing a Day We know the Beginning was in 11013 BC. We also know the first day was a Sunday; but which one? In the abovementioned article, the date of the Flood is proposed to be Sunday 2174990 BC, in the proleptic Gregorian calendar (our modern calendar extended back in time). Our attention will be focused on Sunday, 21711013 BC, a preanniversary of the Flood. These dates share a natural symmetry: Sun 21711013 BC Heaven created, waters separated, earth created
6023Year Intersection between Gregoriancount and 365count Though not the exact daysperyear of our planet, 365 retains great significance as a number. The number 365 is inescapably tied to the concept of a year. Few numbers in the threedigit range are this recognizable. Even the Bible seems to acknowledge the connection, as Enoch went to be with the Lord after a life of 365 years. Though true, for whatever reason, God decreed the Earth's orbit slightly longer, giving us a quadrennial 366day year; 365 remains the perceived reality. The number 365 is tied to symbolic, innate concepts:
The Bible itself contains a reference to 365: Genesis 5:23 And all the days of Enoch were three hundred sixty and five years 365: A hidden "key" to verify dates Hidden within the 365.2425based Gregorian system, is a repeating rhythm between itself, and a concurrentlyrunning 365count (as if on a calendar without leap years) defining a (roughly) 1505year beat cycle. We shall see how the fourth repetition of this cycle forms a unique 6023year link between [Jan/Feb, 11013 BC] and [Jan/Feb, 4990 BC]. As years pass, the insertion of leap days (which are not really extra days; but merely delayincounting days) increases the disparity between the two calendars' names for current dates. Eventually enough leap days are encountered to total a whole year, and the two calendars will briefly regain sync in mm/dd, but will disagree by a whole year. This occurs roughly every (4 x 365) years; the actual formula is slightly more involved. Time required for the first extra year to accumulate is given by: q x 365.2425 = (q+1) x 365 That is, "How many ('q') Gregorian years = exactly one more '365' year?" Solve for q: 365.2425q = 365q + 365 0.2425q = 365 q = 365/0.2425 q = 1505.15464To find the time required for any number of years to accumulate: substitute the "1" in the formula with the desired number of years. This 1505year, 365vs365.2425day pattern is demonstrated by the Biblecalculator's timeconverter: 1. Define year: Default (Gregorian) Here is the readout for the first 1505year convergence: 1502 years = 548594 days, or 1503 sets of 365 days, 0.77 days 1503 years = 548959 days, or 1504 sets of 365 days, 0.53 days 1504 years = 549324 days, or 1505 sets of 365 days, 0.29 days 1505 years = 549689 days, or 1506 sets of 365 days, 0.04 days 1506 years = 550055 days, or 1507 sets of 365 days, +0.2 days 1507 years = 550420 days, or 1508 sets of 365 days, +0.44 days 1508 years = 550785 days, or 1509 sets of 365 days, +0.68 days 1509 years = 551150 days, or 1510 sets of 365 days, +0.93 days Two issues arise: 1.) These yearvalues have a fractionofaday remainder at right, being computed rather than counted; fractional days are not valid in a calendar. 2.) These results are not all 365divisible; they provide a range that must be checked. To resolve both issues, and see which months/years are actually 365divisible, a count must be performed, using two sample dates for each year: one before March 1, and one after March 1 (the leapday demarcation). How does all this help to find a Creation date? There is a special, rare relationship between the calendars of [Jan/Feb 11013 BC] and [Jan/Feb 4990 BC] that can occur only at ~1505year intervals. February of 4990 BC falls into the third of these 1505year intersections with the number 365, since 11013 BC. In this twomonth window, dates share the same mm/dd values, dayofweek, and have 365divisibile daycounts. Both the rarity and the numerical significance suggest an increased likelihood that identical dates in January or February, 6023 years apart such as the suggested 217 and 217 may bracket both the Creation and the Destruction by flood. Starting at 11013 BC, and scanning all of history, there are only eight years containing this 1505year convergence; and out of these 96 months, only 50 also have shared weekdays with 11013: _________________________________________________________ 9509 BC: Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 7998 BC:   Mar Apr May Jun Jul Aug Sep Oct Nov Dec 6494 BC: Jan Feb           4990 BC: Jan Feb           3486 BC: Jan Feb           1982 BC: Jan Feb           471 BC:   Mar Apr May Jun Jul Aug Sep Oct Nov Dec 1034 AD:   Mar Apr May Jun Jul Aug Sep Oct Nov Dec _________________________________________________________If we narrow our focus to February 11013, only the BC years 9509, 6494, 4990, 3486, and 1982 have dates in February with daycounts divisible by 365 and which share the same weekday. The odds of choosing one of these five anniversary years at random, out of 13023 numbered years (not counting 11013), are: 5/13023 = 1 in (13023/5) = 1 in 2604 Competing definitions of yearlength such as Mean Tropical (365.24218967), Mean Tropical Rounded (365.2422), Julian Average (365.25), or Sidereal (365.256363051) fail to register the 6023year alignment. The closest any reaches (365.2422) is 6024 years, a span we can reject due to our confidence in the 6023year interval from Creation to Flood. Of all these nearly identical values, only the Gregorian (365.2425) produces this 365centered harmony.
The 2,200,000Day Interval If Sunday 21711013 BC was "the First Day", then the creation of Man would have occurred on Friday 22211013, "the Sixth Day". Starting here at Day Six, and going forward in time 2,200,000 days, we arrive at 7174990 BC. This would be the seventeenth day of the seventh month (Genesis 8:4), the end of the 150day period when "the waters prevailed upon the earth" (Genesis 7:24) to destroy man. Although every living thing might easily have died before this day, the waters expressing God's anger prevailed until some full measure of punishment was reached on day 150. On this day the waters were finally abated and the ark rested (Genesis 8:3,4). (For an untangling of Flood events, see Assigning Dates to All Flood Events on this website.) Regarding the 2,200,000 days: A case can be built for the number 22 signifying God's wrath being satisfied. In this case, 22 is multiplied by 100,000. For perspective on the rarity of 100,000day intervals, know that they occur only every 273 years. A study by the same author, The Number 22, also appears on this website. The Moon was created on the Fourth Day: Genesis 1:1419 (Day Four) 14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: It can be shown with reasonable confidence that there was a full moon on 22011013 BC the Fourth Day, if 21711013 was the First Day. The validity of this claim is demonstrated elsewhere on this website: Lunar Motion and Data > Moonphase for 22011013 BC. As the Moon orbits the Earth, its daily rate of progress is only about 12 degrees. If the lunar orbit were a giant clock dial, the Moon would progress only about two minutes on that dial per day. (counterclockwise) So the position where the newly fashioned Moon was first placed, would basically be the place it would inhabit that whole first day. Reasons to Expect an InitiallyFull Moon 1. It would serve to frame a Creation Day candidate, such as 217, with increased certainty. 2. An initially full Moon would instantly demonstrate the full glory and purpose God intended for it: 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night.... 3. Careful reading of Genesis 1:1419 hints that it immediately began serving as the light source God intended: 15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. The Full Moon is Unique Among MoonPhases While obviously brighter than other nights, there are two hidden factors that enhance the full Moon's illuminating power greatly, even over the nights preceding and following: At fullmoon, the initial light source (the Sun) is directly behind us, throwing its light over our shoulder, as it were, onto the Moon. As a result of this alignment, two things happen: 1. "When we look at a full moon, we don’t see any shadows since the sunlight is coming from pretty much our direction. When we look at a first quarter moon, the light is coming in from the side and there are lots of shadows. So for any given area of the surface, we’re seeing less of it illuminated than we would when the light is more direct. (It turns out that effect happens on more than one level: not only are there shadows from major features like mountains and crater walls, but also on a much smaller scale in the way the light is reflected from the top few millimeters of the lunar regolith, the deep fine powder that covers the moon.)" [1] 2. "Some people also claim that there’s an effect from millions of tiny glass beads in the lunar regolith, formed from millions of meteor impacts. These glass beads act like retro reflectors, reflecting most of the light that hits them back in the direction it came from." [2] Were the Moon a large smooth spere, with no such contours or glass beads, there would be an expected two to threefold increase in reflectivity (brightness), from one of the quarters (halflit), to the full Moon. Yet the actual increase in brightness is closer to 14 times, with perhaps 40% of this increase occuring between [full] and [night before or after]. [3]
Creation lagtime fits FullMoonCycle It has been suggested in these studies that our currentlyused Gregorian calendar may have been intended as the tool to connect the Genesis Flood "dates" to other Biblical dates, with totheday precision. Also suggested is that if God did plan this, He may have arranged confirming signs, such as:  A harmonious structure of dayspans (2,2000,000, etc.) Further still, there may also be confirming signs with the only celestial body not connected to the Gregorian mechanism: the Moon.  A possible new moon to mark the Flood monnth (covered in companion study) The FullMoon Cycle Specifically, we are interested in an obscure lunar period known as the FullMoon Cycle (here abbreviated as FMC). We have focused on 217 as the possible date when Creation began. Admittedly, this date sounds random. Also seemingly random is the FMC duration of 411.78443029 days. Yet together, these numbers produce a noteworthy time interval that seems notsorandom. The FMC (roughly 1+1/8 years) is the period required for the Moon's elliptical orbit to circle the Sun until the exact same part of the ellipse is again facing the Sun. Or essentially, the time required for the elliptical lunar orbit and the Sun to circle each other.
When compared to a 365day year, the FMC is longer by ~46.78 days: Full Moon Cycle 411.78443029 Common Year  365 ____________ 46.78443029 Why the difference? Imagine the ellipse is pointed at the Sun, as though "looking" right at it. After one counterclockwise lap, it has shifted its gaze slightly to the left of the Sun (precessed slightly counterclockwise)... requiring it to travel a little further to "see" it. The lap is the year; the littlebitfurther is the ~46.78 days. The date 217 is 47 days from 11. And because The First Day was an "eveningmorning", the day properly began at on the Gregorian timeline at ~6:00 PM (sunset) on 21611013 BC, narrowing the interval by a quarterday to ~46.75 days. When asking "which direction to shift the day when converting", consider: The shift from [standard day] to [eveningmorning] is only six hours, if one combines each day with the evening before; as opposed to an 18hour shift the other way. Back to the Full Moon Cycle something of little interest to anyone not an astronomer predicting eclipses: Starting at sunset on 21611013, and turning the clock back (hypothetically) exactly one FMC (~411.78 days), one arrives at the start (12:01 AM) of 11, the previous year... to within an hour or so. There are 9883 hours in a Full Moon Cycle, which argues against coincidence. This would seem to bolster the selection of 217 as Day One, and shed light on the "Creation lagtime"; perhaps dissolving some of our concerns that "217 is an odd starting point; why not 11? ". As an aside, and perhaps not a minor one, it is noted that a similar FMCphase stretches from 216 (sunset) in Year A, to [midday] on 43 (noon, Resurrection day), in Year B... provided that either Year A or B is a leapyear. The following are valid examples of such:
 12:01 AM   6:50 PM   1:40 PM    < FMC >   < FMC >   1111014 BC* 21611013** 4311012  12:01 AM   6:50 PM   1:40 PM    < FMC >   < FMC >    1131 AD*** 21632 AD** 4333 AD* Hypothetical date before start of time in 11013 BC ** Leapyear *** 1131 Is the decadestarting benchmark date before the Crucifixion and Resurrection.
1472 Precessions of Moon's elliptical orbit ( 4,756,797 days ) The previous section on the Full Moon Cycle introduced us to the fact that the Moon's orbit around the Earth is not a perfect circle, but slightly elliptical (oval) in shape; and that this ellipse undergoes a gradual precession, or rotation.
Over time, this mild precession accumulates to a full 360^{o}, regaining the starting orientation, and pointing the ellipse in the same direction*.
One complete precession of the Moon's orbit requires ~3231.5 days; this was calculated by using the fullmooncycle (FMC; explained above) and Gregorian year length (discussed on the Year Types page on this site). 1472 Cycles: Seemingly not a random number The dayspan from (proposed) Creation to final Destruction can be shown to accomodate precisely 1472 of these ~8.85year precession cycles.
The prime factors of 1472 are of special interest.
1472 = 2^6 x 23 = 2 x 2 x 2 x 2 x 2 x 2 x 23 1. Calculation of cyclelength The precise value of this cycle, in days, is obtained as follows: 1. Find the difference in arc between Gregorian year and Full Moon Cycle (slightly longer): a. Find the difference in period of each: Full moon cycle 411.78443029 days Earth year  365.2425 ____________ difference 46.54193029 days b. Find arc swept in 46.54193029 days: Days travelled past oneyear mark arc ______________________ = _____ Length of year in days 360 46.54193029 arc ___________ = _____ 365.2425 360 Crossmultiply, then divide, to find arc: 46.54193029 x 360 / 365.2425 = 45.873891741514199470214994147724 Answer: Difference in arc, Gregorian year and Full Moon Cycle = 45.873891741514199470214994147724 degrees 2. Find the number of FMCs that must transpire to accumulate 360 degrees rotation of the Moon's elliptical orbit (precession period): In other words, how many times does: 45.873891741514199470214994147724 ...fit into 360? 360 _________________________________ 45.873891741514199470214994147724 = 7.84760102823831546759853994874 FMCs 7.84760102823831546759853994874 x 411.78443029 days (1 FMC) ___________________________________ = 3231.5199185563329371743597272277 days 2. The precise fit of 1472 cycles The days from 21711013 BC (projected Creation: Day One) to 10212011 (anticipated Destruction) add up to 4,756,800 days. The very nearly matches 1472 lunarorbitprecessions: 3231.5199185563329371743597272277 x 1472 ___________________________________ = 4756797.3201149220835206575184792 days There are sufficient digits after the decimal in our FMC value (411.78443029 days) to insure its accuracy in achieving this daycount. When an artificial digit ( 5; the maximum rounding error) is placed after the last digit in our FMC value: [411.784430295 days], the result changes the ~4756797.32 dayspan by only 0.00432 seconds. Assuming then that our numbers are sound, how do we account for this difference of nearly three days? Remember, there were three days in the beginning when the Moon was not yet formed. Could this ~4756797.32day interval be not an expression of the entire span of Time, but more fittingly, the exact length of the Moon's existence? The daycount from Creation to anticipated Destruction, as proposed here, is 4756799 (not incl). Where can the 4756797.32 dayspan fit in, if the Moon was created some time on Day Four, and is to face destruction on 10212011? Earliest Moon could be created: Sundown, 21911013 (Biblical start of Day Four) Latest Moon can be doomed: 11:59 PM, 10212011 Find window: →Add 1. Daycount from [12:01 AM on 22011013] to [12:01 AM on 10212011] (not incl) (12:01 used for clarity: actually 12:00) ___ 2. ~6 hours on 21611013 ___ 3. 24 (23:59) hours on 10212011 (the "inclusive" day) _______________________ 1. 4756796.0 days 2. 0.25 3. + 1.0 __________ = 4756797.25 days This value is 0.07 days over the duration of the 1472 lunarorbitprecessions. This difference of [1 hr 41 min] may be within the estimationerrormargin between estimated sunset (6:PM) and actual sunset at the start of Day Four. Nonetheless, the ~3231 days between precessions is a distant 8.85 years thus an hour or two difference is minimal in this span of 77,556 hours. Yet intriguingly, there is a seemingly plausible accounting for this extra time: These two hours (roughly) could be explained as the waiting period from day's end (midnight) in Jerusalem, to the arrival of midnight (day's end) at the prime meridian (Greenwich Mean Time), two time zones to the west, in England. This would be an almost expexted consequence, had God as suggested in this book made the switch from Hebrew to Gregorian time systems in these latter times, as GMT is the "zero" timereference point for the world.
Seventeen, 7000, and the Full Moon Cycle The numbers 17 and 7000 are expressly involved in God's plan for the world: The calendar of history involves a 7000year span from the year of the Flood to the year of final Destruction.
The Flood hit on "the seventeenth day". While the elements of a date are not routinely open for numerical analysis, in this case the wording is from the Bible itself. Hidden within the timing of the Full Moon Cycle (explained above) is a gearing of 17 such cycles to every 7000 solar days: Full moon cycle: 411.78443029 days x 17.0 ____________ 7000.33531493 daysAn internet search for any mention of this 17 : 7000 ratio yielded no results. Perhaps the numerical significance of 17 and 7000 is lacking to all but the Bible student. Yet harmonious relationships between celestial cycles, being of rare instance, are not typically ignored by astronomers. Other similar gearings are quite wellknown, such as: [19 tropical years] ~= [235 synodic months]
Creation → Destruction: 4,756,800 Days [ 21711013 BC ] to [ 10212011 AD ] [ Creation begins ] [ Destruction? ] = 4,756,800 days (incl * ) = 10^2 x 2^4 x 3 x 991 = 4800 x 991 = 2400 x 1982 * "Inclusive" (the counting of one extra, to encompass both start and end points) is highly appropriate here, as one is interested in the total number of days that would exist (4,756,800), a number 1 higher than the dayspan (4,756,799). The Factor 1982 The divisor 1982 is 1/2400 of 4,756,800 days. It seems to bear significance concerning Christ, in at least two ways:
1. The time from Christ's appearance as Savior, until His return at the end of the world, is 1982 years. Essentially, this is the length of His saving ministry on the earth.
2011 AD Anticipated End of world [1021]  29 AD Jesus announced as Lamb of God [925]  = 1982 years 2. The time from Christ first teaching in the temple, to His spirit leaving the churches, is also 1982 years (inclusive), comprising the period when: "I [Jesus] sat daily with you teaching in the temple" (Matthew 26:55)...until: "the time that the daily 1988 AD End of Church Age [521] / Great tribulation begins  7 AD 12+1/2yr old Jesus found in temple at Passover  = 1982 years (inclusive)
For either of these 1982year timespans, the following applies:
Also, regarding the yearspan [29 AD  2011]: An interesting dayspan exists between two significant dates within those years: 925 29 AD (Baptism of Jesus) to 2172011 AD (Proposed 7000th Flood anniversary)  = 723690 days (not incl.) = 10 x 9 x 11 x 17 x 43 = 10 x 11 x 43 x 153 The Prime Factor 991
As for the prime divisor 991: it may seem insignificant, until expressed as:
991 = 1000  9That is, 991 is 9 short of 1000. Alternatively, 991 + 9 = 1000 There is an interesting timeline involving the 991 : 9 ratio: Israel End of Flood reborn world? 4990 1948 2011 ===== ===== =====    991 x 7 = 6937 years: 6937 yrs  + 9 x 7 = 63 years:  63 yrs  = 1000 x 7 = 7000 years: 7000 yrs First Week → Final Week This example utilizes the date 112011, which we shall call a "benchmark date"– a concept further demonstrated in the followup to this study, Further Validation of Gregorian Dating. A benchmark date is basically a date that denotes the [beginning or end] of a [millennia, century, decade, or year] that contains the keydate. Hence 1231 and 11 are the two possible benchmark dates in the Gregorian system. The following tidy fit with 112011 serves the dual function of reinforcing both: 1) the selection of [21711013 BC] as Day 1; and
[22311013 BC Sat] to [1 12011 AD Sat] = 4756500 days [1 1 2011 AD Sat] to [5212011 AD Sat] = 140 days ...from which we derive the following:
