I just looked up Joseph Rutherford on www.time.com and found this article:

Apparently, considering 1935, 1975, etc., someone ignored his "predictions" of when the end would come. On page 2, it says, "Cosmos III is assumed to have begun with the War and to end in 2874. This is the time of "Christ's invisible reign." " It's so interesting how they can preach something one day and get all their "followers" to believe, then change the information, get eveyone to forget the old and belive the new as if the old information never existed.
So, if Rutherford was right (I doubt it), then we've got another 600+ years to go before Armaggedon. I wonder what's next.
