The reign of the antichrist

In my post "another look at the timeline" I may have inundated some of you with so much info that the point was missed. If so I am sorry.

To simplify this timeline and to establish its validity, I would like to concentrate on the 1290 day reign of the antichrist.
First, I believe that Rosh Hashanah is the Day the battle of armageddon takes place. I also believe it is over quickly because I think Jesus enters the temple this same day and begins to fulfill the fall feasts. The bible says:
Rev 16:16 And he gathered them together into a place called in the Hebrew tongue Armageddon.

Rev 19:19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.


Rev 19:20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.

Up until this day the antichrist is still in charge, but when Jesus steps down on the Mount of Olives EVERYTHING changes. The first thing He does is get rid of the antichrist and his false prophet. The bible says:

Rev 19:19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.


Rev 19:20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.

Now since this is the LAST DAY of the antichrist's reign, and he reigns for 1290 days, it only stands to reason that we can count back and figure out when he entered the temple and set up the "abomination of desolation". The bible says:

Dan 12:11 And from the time [that] the daily [sacrifice] shall be taken away, and the abomination that maketh desolate set up, [there shall be] a thousand two hundred and ninety days.

So from Rosh Hashanah 2017, which is Sept. 22, 2017, counting back 1290 days takes us to March 12, 2014. This time period includes the 1260 days of the 2nd half of the tribulation plus the 30 days of repentance that takes place beginning on Elul 1 (month of mourning) and ends on Rosh Hashanah.
Now counting back from March 12, 2014, we subtract 1260 days for the first half of the tribulation and we come to the very last day of the Feast of Tabernacles on Sept. 29, 2010. I believe the rapture will happen after sunset in Jerusalem at the end of the last day of Tabernacles.

With this scenario we cover the 2520 days of the 7 year tribulation up to Elul 1, when I believe the sign of the Son of man appears and all the tribes of the earth mourn. The bible says:

Mat 24:29 ¶ Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:


Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.

Notice that verse 29 says "after the tribulation of those days"......verse 30 "then shall the sign of the Son of man appear". The second half of the trib (1260 days) ends on Elul 1. But the antichrist still has 30 days left to reign. That ends on the 1290th day which falls on Rosh Hashanah, the day Christ throws him in the lake of fire and destroys the armies on the plain of Megiddo at the Battle of Armageddon.
The 1335th day is 45 days after this and lands on the 17th day of Cheshvan which is Nov. 6, 2017. This is the day the rain started to fall in Noah's Flood.
The days of Noah.

I really hope this simplified it for you. I realize there are those that want to defend their positions and theories. I want to do that to. But please show me scripture the way I have done. I don't mind being wrong because I want to learn. But change my mind with scripture.
