Shalom All:

Granny Priscilla made reference to The World-wide Flood at Noah's time.

I have attempted a time-aligning of the Jewish feast calendar to the event and
these are the results I came up with.

1 - Noah enters Ark = Cheshvan 10 or 11
2 - The flooding begins = Cheshvan 17 (Genesis 7:11)

3 - The waters stop and the Ark is on Ararat = Nisan 17
     5 months (150 days) from start.

4 - Mountains tops are visible = Tamuz 1
5 - Ark windows opened 40 days after Tamuz 1 = Av 10
6 - Raven (and Dove) are released/return = Av 11
     [but Raven continues flying back/forth till "earth dry" - Tishri 1]
7 - Dove released and returns with leaf = Av 17(?) or 18
8 - Dove released and no return = Av 25
9 - The earth is dry BUT Noah remains on Ark = Tishri 1 (see also Raven at #6)

10 - Finally Noah removes THE COVER of the Ark, earth is dry, ALL leave Ark =
Cheshvan 27

Nisan (#3) is during Pesach.
Tamuz (#4) has the Days of Prayer - Tamuz 17 to Av 9.
Just after Av 9 the bird account happens.
Tishri 1 (which we are coming to) has the earth dry BUT Noah stays on-board.
For about two months they remain on the Ark before coming out = Cheshvan 27

This is one year and 10 days from entering the Ark.
I'm sure there are lessons here for us.
