Revisiting Sunday Letters in Creation Year

Suppose Jesus was crucified 7 April / 14 Nisan AD 30, born late in 6 BC. I read this in 1000 raisons à croire before giving it away.

Suppose Jesus was born according to Roman Martyrology.

This would put AD 30 as 5235 Anno Mundi.

Could Adam have been created a Friday 7 April or a Friday 14 Nisan before Anno Mundi 1?

365.24219 * 5235 = 1912042.86465 or 1912043 days.
1912043 / 7 = 273149

Yes, 7 April would have been a Friday.

Would it have been a 14 Nisan?

1912042.86465 / 29.5305888531 = 64747.8746245617648313

No, 7 April before AM 1 would not have been a multiple of whole Lunar months prior to 7 April AD 30.

1 - 0.8746245617648313 = 0.1253754382351687
0.1253754382351687 * 29.5305888531 = 3.7 days

To get back to 14 of Nisan, it would have been on creation day 2 or 3. 4 or 3 days before Adam was created.

Is there a problem with this?

Yes, 5199 AM being the birthyear involves a span of 2242 years prior to the Flood, and the actual first text of Genesis 5 would arguably warrant 2262 years instead.

5199 + 20 + 36 = 5255
365.24219 * 5255 = 1919347.70845 or 1919348 days

1919348 / 7 = 274192.5714285714285714
7 * 0.5714285714285714 = 3.9999999999999998 or 4 days.

So, to get back to a Friday, Adam would have needed to be created on 4 April.

1919347.70845 / 29.5305888531 = 64995.2399526403198068

And also 7 April would not have been a 14 Nisan ...

1 - 0.2399526403198068 = 0.7600473596801932
0.7600473596801932 * 29.5305888531 = 22

7 April, 38 March, minus 22 = 16 March would have been a full moon, if that many days before Adam had existed, and same is true of ...

0.2399526403198068 * 29.5305888531 = 7.08...

14 April. A week after Adam's creation, if we replace March 25 with 7 April. No, ten days after his creation.

PS, other problem, Jesus probably was crucified a Friday 15 Nisan and "day of preparation" in John doesn't mean 14 Nisan, just Friday./HGL

PPS, unless, see the update on this one:

Assorted retorts from yahoo boards and elsewhere: Judaism Apostasised, Catholicism Didn't

The date, now ... two options.

Jesus was crucified the 15 of Nisan and the illegal process was taking place when passover had already started, adding to the guilt.
Jesus had begun Nisan one day earlier and counted 15 while the Temple counted 14 (it was an empirical luni-solar calendar, and Jesus was away in Galilee and couldn't know when the Temple announced the new moon), or Jesus had been allowed to celebrate passover one day earlier by the Temple (which up to above crime still had authority, Hannas or Caiaphas was still the last Pope of the Old Testament, so to speak).

One could add it seems Didache said Jesus was captive more than one night, so in that case the case in the temple was perhaps held the night before the one before Pilate). Liturgy compresses the captivity to the night from Maundy Thursday to the taking down from the Cross on Good Friday in a way the Gospels, if so allow but don't require. That's a third option.
