The Spring Feasts were fullfilled in sequence all in the same year so won't it be the same for the Fall Feasts?  Could the rapture happen one year and then in seven years The Day of Atonement, Tabernacles?
 
Maybe The Feast of Trumpets is not relevant to the rapture of the church but to some other rapture; although this year's feast does seem to have some special sigificance.  It seems to me that Trumpets, Atonement and Tabernacles will be fullfilled on their respective days all in the same year just as the Spring Feasts were.
