That's old light, Slim,
If the 7 times between the fall of Jerusalem and God appointing Jesus as king were calculated out of 365, and not 360 day years, and assuming we keep the - 607 date as the start of the period of time, we would get 7 x 365 = 2555 years, and 1914 would become 1949 (607 + 1949 - 1 = 2555) as the beginning of the last days ! and if we agree with historians who say that Jerusalem fell in - 587, the last days began in 1969.
Just add 120 years to make room for anti typical Noah's days and you expect ARMAGEDDON FOR 2089, or 2069 (about the date Issac NEWTON foresaw) if you stick to - 607.
