How was that date determined?
You know todays calendar is different from what was used 2000 years ago.
I think we've gone through 2 or 3 major changes (I forget the details)
So a simple linear count of days or years won't work.
That was one of the flaws of the "12-21-2012" doomsday.
In order to count the four-digit numbers in the Book of Daniel, at some point one must use a lunar based (30 day) fixed calendar, as the prevailing teaching in chapter 9 regarding the 70 weeks of years prophecy introduces the concept of a half a week of years, that is 3.5 years, which is also expressed as 42 months (lunar). It is also expressed as a time (one year), times (two years), and a half a time (.5 years), which when added together equal 3.5 years, the half a week of years. It is also expressed 1,260 days, which is how we find it in chapter 12, reminiscing, so to speak, of the half of the week expressed in chapter 9. But then two more number are given, 1,290 (3 years, 7 months lunar), and 1,335, what becomes a date of blessing. What would probably help you to understand at this time is for you to realize that I am one of the most mentioned kings foretold in the Book of Daniel, I have had an intimate perspective and curiosity to understand the meaning of the book. I basically only prayed and read for more than forty years until the summer of 2012 A.D. when I was shown how the four-digit numbers align with major Feast Days of Our Lord Jesus the Christ, beginning at a point in time after a 'key' prophecy was fulfilled, which was an event based prophecy, the 95th quatrain of "Les Prophecies" in Michel Nostradamus' Book IV. My three older brothers are the three kings foretold in the opening of chapter 11 in the Book of Daniel. The quatrain indicated "rule by two", referring to when the middle of the three became comatose on February 12, 2009 A.D. after an automobile collision. This triggered the 3 year, 7 month Roman calendar key opening prophecy period leading directly into the 3 year, 7 month lunar Book of Daniel counting on September 12, 2012 A.D. The main page at my website includes a tally of these dates, even until the 2,300 day period of Daniel 8:14 is reached, when the "temple is cleansed", and the King of kings returns.
