Now now boys, Freddie Franz has told you that a year in Bible prophecy is 360 days long.
Except it isn't when we talk about the 2520 years that run from 607B.C. E ( a year when nothing of historical note took place) down to 1914 C.E.
These years are solar years, otherwise Freddie, and before him Russell and before him other numerologists would be just over 37 years short of 1914.
So to make it clear, when the Angel told Daniel that 7 times would pass over the king of Babylon, in his mind the Angel meant 7x360. he did not mention this to Daniel, who, poor chap may have thought that the Angel referred to Babylonish or even Jewish years.
But in the fulfilment of the prophecy (not the fulfilment mentioned in Daniel by the king himself, but the "greater" fulfilment) the years would be solar in length and would run from a year when nothing happened to the magic year of 1914 when nothing happened either that had really been prophecied in the Bible.
Put like that you can see why Jesus was forced to choose the Bible Students/Rutherfordians in 1919, they were teaching such wonderful truths at the time.
Case closed, JW's are "evidently" God's organization.
