Miller Time
For its own End Times best of, Time called William Miller "perhaps the most famous false prophet in history." Miller became a one-man propaganda machine for his specific yet elastic prediction that the world would be "engulfed in fire sometime between March 21, 1843 and March 21, 1844." His numerous followers, as many as 100,000 and known at the time as Millerites, "sold their belongings" and "took to the mountains to wait for the end." When March 21, 1844, came and went without the second coming of Christ, Miller moved the "torch by" date from March to October. After the "Great Disappointment," his loyal followers "explained it away yet again," decided to get out of the prediction business, "and went on to found the Seventh-Day Adventist movement."
