Always wondered about the specificity surrounding the details of the flood--making it clear it was the 2nd month and 17th day along with all of the other details. 

Though I don't know exactly what it is or could be, I recall a different 47 day period relating to Moses and Pentecost or 50 days, and the Lord saying "Be ready against the 3rd day"

Passover is Nisan 14 or 14 days into the new year. For those unclean by touching of a dead body or on a far journey, it's delayed by 30 days. That means It would be 2nd month 14 days or the 44th day.

Passover, Unleavened Bread, and Firstfruits happen over a week, just like there was a 7 day warning? and rain before the waters of the deep broke forth. 

I've heard "3 days of darkness" prophecies countless times over the years regarding dreams and visions of the very last days and the rapture. 2nd Passover happens after 44 days--3 days of darkness would make it 47 days, "as in the days of Noah". Feel free to suggest any pieces of the puzzle you  think are missing.

These letters would be posted by John on 5/7 which is past 2nd Passover as well as the coronation of King Charles on 5/6. Hopefully nobody ever reads this because the rapture happened. It has to be close!
