Is the temple still desolate?
If the temple is still desolate, the 70 ad Jewish revolt wars is not the war that completes the 70 weeks.
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end (<<<< of the 70 weeks>>>>) thereof
shall be with a
flood, and
unto the end of the war desolations are determined.
Matthew 24:39 And knew not until
the flood came, and took them all away; so shall also the coming of the Son of man be.
The war is the war of Revelation 16, Revelation 19, against Jesus.
the flood is this from Daniel 11:22 & Daniel 11:31 (flood of arms in verse 22
Daniel 11:22 Interlinear: And the arms of the flood are overflowed from before him, and are broken; and also the leader of the covenant.
this flood of armies are the locusts of the 5th Trumpet that lasts for 5 months. then they place the abomination statue that desecrates the temple. This is Luke 21:20's 'abomination army' that places the abomination statue.
How does Daniel 8:13-14's 2300 evenings & mornings relate to Daniel 12:11-12's 1290 days & 1335 days?
Here, imo, is how Revelation is laid out.
The Biblical month is a lunar month which is 29.5 days. So, 5 months is 147 days and 42 months is 1239 days (42 x .5 days = 21 days shorter than 1260 days). Thus, a literal reading of Daniel 12:7's 'time, times, and half time' is 42 lunar months, 1239 days. 1239 days (42 months) + 147 days (5 months) + 1239 days (42 months) = 2625 days = 1290 days + 1335 days.
Daniel 8's 2300 evenings & mornings (notice it says there that 'then the sanctuary will be reconsecrated') = 1150 days. It takes 7 days to sanctify the sanctuary (Ezekiel 43:26). So, the sanctuary will be trampled for 1143 days with a lack of sacrifice or bad sacrifices, then 7 days to reconsecrate it.
147 days of locusts + 1143 days of the abomination = 1290 days Dan 12:11
And from the time that the regular burnt offering is taken away and the abomination that makes desolate is set up, there shall be 1,290 days.
the locusts take away the daily sacrifices: Joel 1:4-9
4What the cutting locust left,
the swarming locust has eaten.
What the swarming locust left,
the hopping locust has eaten,
and what the hopping locust left,
the destroying locust has eaten.
5Awake, you drunkards, and weep,
and wail, all you drinkers of wine,
because of the sweet wine,
for it is cut off from your mouth.
6For a nation has come up against my land,
powerful and beyond number;
its teeth are lions’ teeth,
and it has the fangs of a lioness.
7It has laid waste my vine
and splintered my fig tree;
it has stripped off their bark and thrown it down;
their branches are made white.
8Lament like a virgin wearing sackcloth
for the bridegroom of her youth.
9The grain offering and the drink offering are cut off
from the house of the Lord.
The priests mourn,
the ministers of the Lord.
Here is the star sign I reference in the graph.
Mercury & the moon form the arms of the cross, Jupiter & Venus are in conjunction, and Saturn forms the bottom of the cross.
the great tribulation starts on a winter solstice Matthew 24:15-24, emphasis on verse 20
Pray that your flight may not be in winter or on a Sabbath. 21 For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be.
but the context here is all events of the seals, trumpets, & bowls.
the 'middle of the 70 '7's of Daniel 9:24-27 is half of 490 years (and 7 years) which is 245 years. July 4, 1776 Declaration of Independence + 245 years is July 4, 2021, also the 1290th day from the winter solstice, 2017. (bible days go dusk to dusk: dusk Dec 21, 2017 add 1290 days gets to dusk July 3, 2021.
So, going 42 months prior or after July 4, 2021 would give us the 7 years of covenant.
So, like you said in the OP, there is a war prior to the 7 years, yes that appears to be the case. It would be the 2nd Seal war. The true 5 months of Revelation 9's 5th trumpet would be 5 months prior to July 4, 2021. Looking at the graph, we can see that the 2nd Trumpet's burning mountain (which we know is the fall of Babylon from Jeremiah 51:25) occurs at the end of the 1239 days, the initial 42 months.
After the initial 42 months people are 'coming out of the great tribulation' Revelation 7:14. At the 1290 days marker, there are 3 divisions of people: 1) the beast from the sea kingdom, 2) the faithful who have come out of the tribulation and are now gathered (there is no 'whisked away rapture') who now become part of the 2 witnesses/ 144,000 sealed, and 3)
the false prophet who comes out of the gathered group to lead the faithful gathered astray. Just like in the Exodus story, after the Hebrews came out of their great tribulation with Egypt, Moses' brother Aaron created the golden calf abomination idol.
At the 6th Trumpet, the 200 million man army is the army of God that is gathered together out of the 'great tribulation' of the 1st half of the 7 years. (Psalm 68:17) the locusts in the 6th Trumpet war are the army that brings the false prophet to power for the last 1239 days/ 42 months of the 1290, then 1335 days combination. these locusts are imitating God's army, they think that the false prophet is God.
You already understand that the false prophet will confirm the Mosaic covenant on a Yom Kippur: within the framework here, it seems that this will occur on Yom Kippur in 2021. (dusk Sept 15 to dusk Sept 16, 2021. Add 1260 days to dusk Sept. 16, 2021 and you get dusk Feb 27, 2025

from dusk Dec 21, 2017 add 1290 days (to break the covenant in the middle of 70 '7's, dusk July 3, 2021), then add 1335 days to get to the same date of Feb 27, 2025

So, the Gog war would take place after "Israel" has been gathered and are living in safety. This gathering happens after people are gathered at the 6th/ 7th Seal, then the gog war can happen. If it results in a physical temple, then the gog war would happen at around the mid point/ July 4, 2021.
