The fall feast days do indeed picture future events in roughly the order they occur. For example, the feast of trumpets is the first of the fall feast days. It indeed pictures the 2nd coming of Christ:
1Th 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
1Co 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Rev 11:15 And the seventh angel sounded (his trumpet); and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign forever and ever.
Atonement, the next of the fall feast, pictures the putting away of Satan after the return of Christ:
Rev 20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
Rev 20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
Rev 20:3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Compare this to the ceremony held on Atonement listed in Leviticus 16.
Tabernacles does indeed picture the millennium, but there seems to be a separate sabbath that occurs on the 8th day after the 7 days of the feast of tabernacles:
Lev 23:36 Seven days ye shall offer an offering made by fire unto the LORD: on the eighth day shall be a holy convocation unto you; and ye shall offer an offering made by fire unto the LORD: it is a solemn assembly; and ye shall do no servile work therein.
Lev 23:39 Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the LORD seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath.
Joh 7:37 In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink.
Because of the way it's worded here, many refer to this as the "last great day". It pictures the great white throne judgment which occurs after the millennium.

Thank you all for your comments. I’ve learned a
lot and appreciate your thoughts. Sorry I wasn’t
able to host the thread after I posted. I was called
away to a project. Please forgive.
It’s very exciting to think that Jesus could return
any minute and that yes, we could be praying with
the last one ... THE one God has been waiting to hear
say “YES”!!!. Keep doing the work of an evangelist.
Don’t give up. Occupy until He returns.
I liked what DO said about being ready. Jesus
could return at any time. Maybe today! Look up.
