Throughout Watchtower history dates have been a problem. The usual solution for failed prophetic dates has been to kick the can down the road. This needs to be done with 1914. The generation that will never pass away is now 110 years old and therefore is past its useful life span. The best thing to do would be to find a more recent date to replace 1914 ( kind of like when the Judge replaced 1874 with 1914). I have a proposal. I apologize if someone has already brought this up, but I haven't seen it mentioned.
1914 is based on a period called "The Seven Gentile Times." The Watchtower says that this is the period from the destruction of the Jerusalem temple in 607 BCE to Jesus coming into kingdom power (invisibly) in 1914. The calculation is: seven times equals seven lunar years of 360 days (7 x 360 days = 2520 days). Days are converted to years thus giving us 2520 years. From 607 BCE to 1914 CE is 2520 years. But what if new light reveals that seven times is actually seven solar years? That would mean each year or "time" would be 365.25 days (365.25 x 7 = 2556.75). That means that instead of the "Seven Gentile Times" being 2520 years they would be 2556.75 years. Thus counting 2556.75 years from 607 BCE we would end at the summer of 1951. The generation of 1951 is only 73 years old! No more overlap needed!
Of course 1914 is greatly favored because World War I started. But bad things happened in 1951 as well. For instance the evil United Nations moved into its New York headquarters directly across the river from the world headquarters of Jehovah's Witnesses. The first thermonuclear bomb was exploded. The Cold War and the Korean War. The first Jack in the Box fast food restaurant opened in San Diego. "I Love Lucy" had its television premier. (Just kidding about Lucy).
If the Governing Body likes my idea they are free to use it. All I ask in return is a lakeside villa in upstate New York.
