The seven-year (84 month) tribulation must begin by 'Feast of Trumpets' September 30, 2008 in order that it be over by 'Feast of Trumpets' September 2015 which is the date the next 'Jubilee Year' begins, and we know what happens in a 'Jubilee Year' according to Leveticus. The next 'Jubilee Year' begins on the 'Feast of Trumpets' September 2015 and ends the day before the 'Feast of Trumpets' 2016. This scenario places mid-tribulation (42 months) on or about April 1, 2012. How approptiate!
