180 years ago today the return of Christ was supposed take place based on the calculations of Millerite preacher Samuel S. Snow.

In August 1844 at a camp-meeting in Exeter, New Hampshire, Samuel S. Snow presented a message that became known as the "seventh-month" message or the "true midnight cry." In a discussion based on scriptural typology, Snow presented his conclusion (still based on the 2300 day prophecy in Daniel 8:14), that Christ would return on, "the tenth day of the seventh month of the present year, 1844."[19] Again, based largely on the calendar of the Karaite Jews, this date was determined to be October 22, 1844.
