I read book 2 the EQUATION by Malcom  Isted , very hard to read , for a  non-math scholar !!!
 
But you have to read it all .
 
After ALL of his numbers , he comes up with 2015 in  the Greek that means  epiphaneia   , the ADVENT OF CHRIST (past or future ).
 
Of course he believes it will be on FEAST OF TRUMPET  !!!
 
The BIG Jewish year change is in Sept. this year , on Rosh Hashanah.
 
The Hebrew year is interesting TOO.
 
The Lord Bless You
