3. Between March 21, 1843, and March 21, 1844. In 1822, Baptist preacher William Miller vaguely stated that he believed the “second coming of Jesus Christ is near, even at the door, even within twenty-one years - on or before 1843,” based on his interpretations of the book of Daniel. As he shared his views, he developed a rather large group of followers, cleverly dubbed “Millerites.” Though reluctant, Miller eventually set a more precise set of dates at the urging of his followers: namely, the 365 days between March 21, 1843, and March 21, 1844.
