6000 years

I like the math in your theory. Also please consider that the Savior was crucified in 27 AD and the math follows:
BC 1/1/3974 to
AD 1/1/0027 is
exactly 4,000 years; showing that the Savior was born at the end of the 4th-thousand-year period of time and was crucified exactly on the 4th-thousand-year


Secondly, your theory cross-referenced to the Hebrew calendar shows that Adam as well as Christ was placed within and sent out of the garden (Eden for Adam and Gethsemane for Christ) in April.

It is going from January 1st to January 1st to complete one year.
Thus, 1/1/3974 to 1/1/27 is four thousand years.

I suppose if one day was left off so that the date was 12/31/26 then the math is more correct. So, 1/1/3974 plus 12/31/0026 is four thousand years.
However, if the date 1/1/27 is added then it is easy to see the complete year: something like

1) 1/1/2000 to 1/1/2001 is one year
or
2) 1/1/2000 to 12/31/2000 is one year
In both cases it is only one year but having one day difference.

I remember the debate over when the millennium started. It was either 2000 or 2001. Since time started at 1/1/0 and the first year was completed at 12/31/0 and the second year started at 1/1/1 then the year 2000 is the 1st year of the new millennium and 2001 is the second year of the new millennium.

Tomorrow we end the 20th year of the new millennium on the day 12/31/2019 and the next day (1/1/2020) we begin the 21st year of the new millennium. As crazy as that sounds it is correct. It is like the day 12/31/1999 ended the 20th century and the day 1/1/2000 began the 21st century.

So one might say that the last year of the 20th century was 1/1/1999 to 12/31/1999 or 1/1/1999 to 1/1/2000 and both cases they would be correct; with one days difference.

It gives me a headache to think about it.
