The 1914 thing, IMO, is now being toned down. Historically they have used (abused?) that year as the basis for many of the things they used to preach that now are trying to pretend they never said. Back in the late 1800's they claimed that the new order was going to come in 1914. Then "new light" showed that ridiculously convoluted story about Daniel and the 7 times and the Revelations, and 607BC.
The thing is that all that nonsense is based on Babylon being destroyed in that year, 607 BC, but the JWs are the only ones who claim that that's when that happened. All you have to do is go to any library and find that no reputable, credible historian points at that year. Of course, their calculations of the seven times thing miserably fails if things didn't happen in that year. If you ask me, all their calculations fail miserably, period.
