If its 1335 years from the date it was set up, 691, I think we need to do a little math to come to the right number of 365.25 day years
Since the year in the Bible is one of 360 days, and ours is 365.25 days....... 1335 X 360 = 480600 days......divided by 365.25 = 1315.8
Add 1315.8 to 691 and you get 2006.8 give or take a few months......That would put us pretty close to the beginning of the end.
The 1290 day mark would have been around 1962- anything happen then?
BTW others sometimes adjust to 364 days, not your 360, since that was used by the Essenes in antiquity, having exactly 52 weeks and thus 4 quarters of 13 Sabbaths each...
But hey, I hope you are right, for if so then I might be able to live to see it all work out!
