Every 12 out of 19 years there are 2,550 days from Feast of Trumpets to Day of Atonement. And the other 7 out of 19 years there are 2,520 days from Feast of Trumpets to Tisha B'Av (the day the 1st and 2nd Temples were destroyed).
We have good reason, therefore, to believe there are 30 days more at the end of the second 1260 days to the 1290th day, and these additional 30 days are for Jesus to judge the nations
in Matt. 25.31-46 when He returns. Then 45 days more to the 1335th day are to set up Israel as the center of all nations.
Just as Genesis 2 gives the details of Gen. 1, we find that Revelations 12 to 19 give the details of the major points of the Tribulation from Rev. 7 to 11. Rev. 2 & 3 are the church age. Rev. 4 are the 24 archangels in heaven (Michael replaced Lucifer). 24 is the number of administration by these eldest elders of the universe. Rev. 5 recounts the cross. In the 1st Seal there is a bow and arrow that looks like a cross but the arrow has been shot giving Satan a deadly wound (he no longer is able to work in the old man that has died on the cross with Christ of those of us who are born-again).
Would Jesus wait 2000 years after picking up the scroll to open the seals of the scroll? Of course not. So the 4 Seals are the past 20 centuries very general in nature where 1/4 are killed. Whereas in Rev. 9 1/3 are killed. Two different periods. The 5th Seal a few years before the Tribulation starts gives a message to those martyred the past 20 centuries to wait a little longer for Daniel's final seven unfolds.
The 6th Seal gives us the 3 events that occur 2010-2015 before the Tribulation starts at the 1st trumpet (8.7). The 7th Seal opens up the 7 trumpets of the Tribulation. Trumpets are loud like the events of the Tribulation. The 1st 4 trumpets (ch. 8) are the 1st half of the Tribulation. People are not killed in mass yet, only the earth is hurt in various ways. Though the Vatican will be nuked (8.7-11, detail given in ch. 17, particularly v.16) in the first half.
The next 3 trumpets are the 3 woes. Rev. 9 says the 5th trumpet is 5 months, 6th trumpet is 13 months, leaving 24 months for the 7th trumpet for a total of 42 months. The 7th trumpet pours out the 7 bowls of wrath. Bowls are bigger than cups and they are poured silently, because so much is happening so quickly in those last 24 months before Jesus steps down on the mount of olives.
So you can see this is essentially a lock tumbler. Turn the dial to 7 one way for the past 20 centuries, then 7 the other for the events that unfold in the Tribulation then again 7 the other to detail what takes place in the last 24 months. This is what God wants you to see.
I recommend reading all the notes on the left side of this page for any verse you would like additional information on how to correctly interpret God's lock tumbler,
