The Watchtower teaches that the JUBILEE year was celebrated every 50 years.
2015 is the year following the second Jubilee after Jesus Christ received his Kingdom (1914 + 50 +50 = 2014)
WHY the second Jubilee?
Because the number 2 represents shit, which is what this speculation is.
Star-charts at the Kingdom Hall! "Set a course for Alcyone, Mr. Sulu, warp factor 1914."
