Exodus was the April full moon of 1513 BC
The Egyptian new year Pamenot 1 of 1514 BC
preceded the comet approach which started many plagues
globally all over (predictable enhancements in Egypt
because of drifted calendar and religious agricultural laws
bound to it)
that Pamenot 1 new year was in Julian March
which is Gregorian Feb and so the Pamenot 1 that started
in July 2030 BC had already drifted back earlier than the
spring equinox. For this reason the month that Moses
declared as Nisan was not legal Nisan which was to
remain in Pamenot July 2030 BC,
Nisan in Pamenot Jun 1910 BC,
Nisan in Pamenot May 1790 BC,
Nisan in Pamenot April 1670 BC (Gregorian March)
Nisan Pamenot in Julian March 1550 BC (Gregorian Feb)
So Moses was declaring that Pamenot Nisan of 1513 BC
was to be an Adar II and that Nisan would be in
Parmuti where it had never been since Egyptian calendar
inauguration in 2030 BC (July 17), nor since lunar inauguration
in 2018 BC... (brought to Egypt by 75 year od Abram in 1943 BC)
the last year of Shulgi of Ur and 1st year of 12th dynasty.
A fix 19-year cycle to replace the 25-year would not be
declared until Joshua's last year 1443 BC, and Babylon also
did so at Joshua's death in 1442 BC.
So 1513 BC was the first Nisan ever occurring in the month
Parmuti instead of Pamenot, to keep Nisan in Julian April
(Gregorian March) and prevent it from going back into
Julian March (Gregorian Feb). For this reason the traditional
Julian March equinox is from the future centuries when our
Gregorian March would drift into near-equal proximity to
Julian March (700-200 BC).
And so the parting of the red Sea two days after Passover
was in April of 1513 BC. In fact Noah's new year was April 15.

Noah's new year April 21 is Parmuti 13

new Parmuti 1 = Apr 3
new Parmuti 10 = Apr 12
FULL MOON APRIL 13, new Parmuti 11 (old Parmuti 6).
Noahs new year on April 15 is Parmuti 13 (old Parmuti

.
137 Julian = 139; plus 720 = 730 x 360 days = 857 years
as 869 of Noahs 360 days. Plus year 600 as Flood makes it year 1469.
It would seem they crossed the Red Sea on Noah's 360-day new year
1469 which was Nisan 16 two days after full moon Passover.
Now what i am not sure of is whether the words of Moses at that time
saying this is the 1st day of the year for you, this is the 10th day you must
prepare the sheep, this is the 14th day you must stay unleavened for 7 days until the 21st day etc. ARE these all Nisan dates? or is the 1st or 10th some how equal in another calendar to this 14th day they held Passover.
Flood's 7th month of year 600 in Apr 2369 BC (600.5)
plus 869x 360 days as 857 years.
The dates from 2233 BC until prior to 1513 BC
are all new Parmuti 12 because 73x 360 days =
72x 365 days so that despite the 365-day calendar
not existing before 2030 BC, the past 720 years back
to 2233 BC have still drifted or flip-flopped 180 days
in both calendars experiencing 18 leap days for each
72-year cycle. So now either this is coincidence that they didnt
listen to the Sothic facts in 2233 BC, or God himself taught
them such results by the event of 1513 BC.
But they superticiously connected Sothic cycles with
arrival of asteroid and comet impacts, instead of learning that
the penalty or disaster (separation from stars) was their
negligence and incompetence for not acting on calendar knowlege
they already had, for 720 years.
But then we seem to have a God who already knows we will be
this way, and he expects the 6 billion to die for the way they
choose to be. Daniel says desolation is what has been decided on
to teach the lesson until the sanctuary is cleaned.
