Having grappled with this question, I decided to turn to the combined expertise at JWN. My questions relate to the Watchtower's self-determined appointment in 1919:
How does the Watchtower arrive at the year 1919 for its appointment? (Is there a date in 1919?) What Scriptures do they apply? I assume they get to 1918 from Revelation 11 and October 1914. If that is correct, then how do they get to 1919? Is it simply that this is the time when Rutherford was released from prison?
