However, according to a group that publishes research about Jehovah's Witnesses, which is a religion practiced in 240 countries, the creed has a history of prematurely warning of the "End" - before trying to erase such pronouncements from its history.
Monitors point to several previous predictions, such as a forewarning of Armageddon in 1914 – although Jehovah's Witnesses later claimed they had foreseen the outbreak of the First World War, which began in the same year.
A spokesman for website jwfacts.com said: "One of the most misleading statements in Watchtower publications is that they accurately foretold 1914 to be the 'start' of the conclusion of this system of things.
"Rather, 1914 was predicted to be the 'End' of the system of things, the conclusion of Armageddon and the start of the Earthly paradise."
"From 1966 to 1975, the Watchtower regularly implied that Armageddon would arrive in 1975. However, ask one of Jehovah's Witnesses about this date and they will invariably deny there ever being such statements."
