I have heard many attempts to link prophecy with the meaning or schedule of the feasts. And although there may be some connection, you cannot make judgments about prophecy regarding the feasts without proper scriptural evidence. The different phases of harvest do not have a connection scripturally with the judgment and harvest of souls in the last day – at least as far as I can discern. Although it sounds good, Matthew 24, Revelation, 1 Thessalonians 4:13ff, and 2 Thessalonians 2, and all the other passages that detail the Day of the Lord only point to one harvest. The only slight exception is Revelation 20:4ff where the raptured saints are included with the martyrs as the first resurrection.
