Monday | The Flood BeginsThe fountains of the great deep broken up, the windows of heaven openedMonday is the weekday the waters were divided into an above and a below (Gen. 1:6–8) | Genesis 7:11 | Judgment |
| AM 1656 Sivan 26 |
Friday | The Forty Days of Rain EndRain upon the earth forty days and forty nightsThe only Friday in the chronology — the sixth day, on which the beasts and man were made (Gen. 1:24–27) and whose roll-call Gen. 7:21–23 reads back | Genesis 7:12 | Judgment |
| AM 1656 Tishri 14 |
Wednesday | The Waters Cease to PrevailThe hundred and fifty days of prevailing close; the waters are abatedThe same date as the vision, one hundred years earlier — again the eve of Tabernacles | Genesis 7:24; 8:3 | Turning |
| AM 1656 Tishri 17 |
Saturday | The Ark Rests on AraratThe only Sabbath in the entire chronology · the third day of TabernaclesThe Hebrew for its resting is nuach — the root of Noah’s own name | Genesis 8:4 | Sabbath |
| AM 1656 Tevet 1 |
Thursday | The Mountaintops Are SeenSeventy-six days after the ark grounds, another peak appears | Genesis 8:5 | Recession |
| AM 1656 Shevat 10 |
Monday | The Window Opened — Raven, then DoveThe raven goes to and fro; the dove finds no rest and returns | Genesis 8:6–9 | Recession |
| AM 1656 Shevat 17 |
Monday | The Dove Returns with an Olive LeafThe first living green seen in nine months, to the day | Genesis 8:10–11 | Restoration |

Thursday | The Waters Are Dried; the Covering RemovedNew Year’s Day — Noah looks out on bare ground, and waits 56 days moreThursday is the weekday on which the calendar’s own count opens | Genesis 8:13 | Restoration |
| AM 1657 Iyar 27 |
Thursday | The Earth Is Dried; Noah Goes OutThe altar, the burnt offerings, the promise that seedtime and harvest shall not cease, the covenant and the bow in the cloudA Shemitah year — the year of release, when the land rests and debts are forgiven | Genesis 8:14, 20–22; 9:8–17 | Release |
| Span | As the text puts it | From | To | How it counts |
|---|---|---|---|---|
| 7 days | “For yet seven days” (Gen. 7:4) | Iyar 10 | Iyar 17 | Seven clear days. The Hebrew od starts a fresh count from the day after. |
| 40 days | “The rain was upon the earth forty days” (Gen. 7:12) | Iyar 17 | Sivan 26 | Forty inclusive. A plain span anchored to a dated verse counts the anchor day as day one. |
| 150 days | “The waters prevailed... an hundred and fifty days” (Gen. 7:24; 8:3) | Iyar 17 | Tishri 14 | A hundred and fifty inclusive. The number measures the prevailing of the waters, not the distance to Ararat. |
| 40 days | “At the end of forty days” (Gen. 8:6) | Tevet 1 | Shevat 10 | Forty inclusive, anchored to the date in Gen. 8:5. |
| 7 days | “He stayed yet other seven days” (Gen. 8:10) | Shevat 10 | Shevat 17 | Seven clear days — od again. |
| 7 days | “He stayed yet other seven days” (Gen. 8:12) | Shevat 17 | Shevat 24 | Seven clear days — od again. |
| Month crossed | Days on this calendar | Days if every month were 30 | Note |
|---|---|---|---|
| Iyar, after the 17th | 13 | 13 | |
| Sivan | 31 | 30 | Carries the intercalary day that closes spring |
| Tammuz | 30 | 30 | |

| Total | 152 | 150 | The flat-month figure only reaches 150 by assuming the thirty-day month it sets out to prove |
The common argument runs: Genesis 7:11 dates the Flood to the seventeenth of the second month, Genesis 8:4 dates the ark’s resting to the seventeenth of the seventh, that is five months, and Genesis 8:3 mentions a hundred and fifty days — therefore months of thirty days.
Genesis states what the hundred and fifty days measure: “And the waters prevailed upon the earth an hundred and fifty days” (Gen. 7:24). Chapter 8 then says that after the end of those days the waters were abated, and begins a fresh sentence, with its own date, for the ark’s resting. Counted from Iyar 17 as day one, the hundred and fiftieth day is Tishri 14; the ark grounds three days later.
On the counting. Both columns of the table count elapsed days, leaving out the first day and including the last — which is how the thirty-day-month argument counts when it adds a hundred and fifty days to the seventeenth of the second month and expects the seventeenth of the seventh. Taken inclusively instead, the same span gives 153 here and 151 under flat months; the distance from Iyar 17 to Tishri 17 is never a hundred and fifty on this calendar either way. The hundred and fifty days of Genesis 7:24 are a different measurement, counted as every stated span in the table above is counted, with the anchor day as day one.
| Day of month | Iyar — the Flood opens | Shevat — the Flood closes | Weekday |
|---|---|---|---|
| 10 | The seven-day warning | The window opened, the raven sent | Monday |
| 16 | Mid-Spring | Mid-Winter | Sunday |
| 17 | The deep breaks open | The dove returns with the olive leaf | Monday |
| 24 | — | The dove does not return | Monday |
Iyar 1 is day 31 of the year and Shevat 1 is day 304, so the two months stand 273 days apart — thirty-nine weeks, exactly three quarters of the 364-day year. The matching weekdays follow from that gap.
The matching day-numbers do not. Iyar 17 is given outright in Genesis 7:11; Shevat 10 is reached by a different route entirely, from the date in Genesis 8:5 plus the forty days of 8:6. Two independent derivations landing on the same days of their months.
Tishri 14. Noah sees the heaven of heavens quake in his five hundredth year, AM 1556. One hundred years later, to the day, the hundred and fifty days close and the waters abate, AM 1656. Both a Wednesday; both the eve of Tabernacles.
Iyar 27. Noah goes out of the ark onto a cleansed earth in AM 1657. Jesus is taken up from the Mount of Olives on the same date in AM 3957 — both a Thursday, both in a Shemitah year, 2,300 years apart. Set side by side on the Feasts reference. The 2,300 is exactly forty-six Jubilee cycles of fifty years, so the shared Shemitah follows from the span; the shared calendar date does not follow from anything. A second thread runs through both days and is made of words rather than numbers: the covenant sign given on the first was a bow set in a cloud (Gen. 9:13–14), a cloud is what receives Jesus on the second (Acts 1:9), and the throne he ascends to is twice described as ringed by that same bow (Ezek. 1:28; Rev. 4:3). Scripture does not connect these passages; the calendar puts them on one date.
The Enoch Calendar year is 364 days — exactly 52 weeks, so every date returns on the weekday it held the year before. Iyar 17 is a Monday in AM 1656 and a Monday in every other year of this calendar. That is why the weekdays in the table above can be stated at all.
The mechanism is arithmetic; the promise behind it is not. On the day Noah left the ark, the cycle itself was bound: “While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease” (Genesis 8:22). This calendar measures those seasons; it does not guarantee them.
The year is held to the sun by a Leap Week of seven whole days, inserted every five or six years. Because it is a whole week, it corrects the drift without ever breaking the weekly cycle — which is what lets a date a hundred years apart, or two thousand three hundred, keep the same weekday.
