Interesting to see that the 1975 speculation still lives on in muted form among the R&F.
In this particular corner of the JW universe, there are several old-timers who have a variety of dates calculated, from 2005 - 2008, based on the original "1975 marks 6000 years since Adam was created" hypothesis:
-- Adam was 130 was Seth was born, per Genesis 5. Seth was born to "replace" Cain, who was no longer fit to be ancestor of the promised seed. Cain was 100 when he killed Abel (not sure where they get this from). So, Adam was 30 when Cain was born, making him about 30 when Eve was created. Thus Eve, the last direct creation of Jehovah, was created when Adam was about 30, so the end comes 6000 years afterward, 1975 + 30 = 2005 (October, of course).
Oops, just 5 days to go until that is de-bunked.
-- Abraham crossed the Euphrates in 1943 BCE (WT chronology). 1,975 years later, in 33 CE, Jesus died. 1,975 years later, in 2008, is a nice symmetric time for Armageddon (there was some more reasoning on this, but I wasn't paying a whole lot of attention). Plus, if Jesus, "the last Adam", lived for 33.5 years, wouldn't it make sense that Adam was 33.5 years old when he sinned??? So, 1975 + 33.5 = 2008/2009 as the latest date for Armageddon.
And there are others. One particular old-timer said he had been calculating dates for Armageddon's arrival since the 1950's. "What's your batting average?" I asked. The response was a sullen glare and a mumbled "not so good."
