This is what I'd like your opinion on, according to scripture, the 2300 days of Dan. 8, the "midst" of Dan. 9:27 and the 1290 days day of Dan. 12 "all" start on the same day. I also do not believe the 1290 days or the 1335 days are "outside" of the 70th week. The 70th week can't end until Israel fulfills it's goals of Dan. 9:24, especially the last three and that can't happen until "after" Armageddon, 75 days after, imo.
I do see the 1290 and 1335 days as being after... the latter 1260 days. (1260 + 30 = 1290, and 1290 + 45 = 1335).
When you look at all the other examples of the "abomination of desolation" event written in the Book of Daniel, like Dan.8:9-14, Dan.9:27, and Dan.11:21-31, we see a specific order of events. And it is the ending of the daily sacrifices and placing of an abomination idol that spiritually desolates the temple, in that order.
Daniel 8 about the "little horn" also helps us also understand the order past... the 1260 days:
Dan 8:11-14
11 Yea, he magnified himself even to the prince of the host, and by him the daily sacrifice was taken away, and the place of his sanctuary was cast down.
That
"little horn" represents the final Antichrist that will end the daily sacrifices in Jerusalem by the orthodox Jews at the end. That last phrase,
"and the place of his sanctuary was cast down" represents the placing of the idol abomination instead. That supports the idea that for the end of this world, the orthodox Jews in Jerusalem will build their 3rd temple, and start up old covenant worship again with sacrifices.
12 And an host was given him against the daily sacrifice by reason of transgression, and it cast down the truth to the ground; and it practised, and prospered.
Again, that above is about the ending of the daily sacrifice and instead placing of the abomination of desolation idol in false worship, for that is the specific transgression for the end that Jesus warns us about (Matthew 24:15).
13 Then I heard one saint speaking, and another saint said unto that certain saint which spake, How long shall be the vision concerning the daily sacrifice, and the transgression of desolation, to give both the sanctuary and the host to be trodden under foot?
That is above is asking how long with the period starting from when the daily sacrifice is taken away, and abomination idol is placed, and for temple and the Jews in Jerusalem trodden by the Gentiles, a la Rev.11:2.
14 And he said unto me, "Unto two thousand and three hundred days; then shall the sanctuary be cleansed."
KJV
The key to the above answer is that,
"then shall the sanctuary be cleansed." That involves the last event prophesied in Dan.9:24,
"to anoint the most Holy", meaning the future Millennial sanctuary cleansing that Jesus will establish on earth after His future return. That means then, the 'cleansing' of the sanctuary has to be at the very end point of the
2300 days. Then the 2ea. 1260 day periods that make up the whole "one week" must happen prior to that cleansing. So place the 2300 days at the end point, and go backwards for 2300 days.
[------------------------------Dan.9:27 "one week" (7 years)---------------------][--Jesus' return]

1290 days = suggest 30 days after Jesus' return, possibly for the cleansing of the sanctuary.
1335 days = suggests Christ's elect blessed & setup as priests in that sanctuary that will have 'many mansions".
The 2 green periods in the 1st 1260 half I believe represents the false-Messiah's rebuilding of the 3rd temple and then re-establishing of old covenant worship and sacrifices. The building of the temple would have to happen first of course, so the 220 days, and then the Jew's re-established old covenant worship with sacrifices as the 1040 day period.
In Matt.24:15, Lord Jesus said when His servants in the holy land see the "abomination of desolation" of the Book of Daniel stand in the "holy place", then get out of Judea.
Rev.13:4-8 and Rev.11 reveals Satan is to have power over all peoples, including the saints, for 42 months, which is the same 42 month period the Gentiles will be given to tread the holy city per Rev.11. That 42 months is the same timing as the 1260 days. God's "two witnesses" at that same timing are given to prophesy against the beast for 1260 days.
Thus all those Scriptures are pointing to the time of "great tribulation" starting with the placing of the "abomination of desolation" idol in the "holy place" (Jewish temple in Jerusalem) for the end of this world. And when that idol is setup instead of the Jew's daily sacrifices, that is when the tribulation will begin, because the tribulation will be about IDOL worship, bow to it or be killed, like the end of Rev.13 warns with the "image of the beast".
Even Ezekiel 8 with the "image of jealousy" inside the temple at Jerusalem serves as a type of blueprint for that future "abomination of desolation" idol that Jesus warned us about from the Book of Daniel. God hates that abomination. All the various occult pagan worship symbols and images shown there on the walls in secret reveal the past pagan empires revived into one religious worship at Jerusalem for the end.
