The end of Daniel chapter 11 and beginning of Daniel chapter 12 identifies the timing of when the tribulation/plagues of Revelation begin to take place.
"But reports out of the east and out of the north will disturb him, and he will go out in a great rage to annihilate and to devote many to destruction. And he will plant his royal tents between the grand sea and the holy mountain of Decoration; and he will come all the way to his end, and there will be no helper for him. During that time Miʹcha·el will stand up, the great prince who is standing in behalf of your people. And there will occur a time of distress such as has not occurred since there came to be a nation until that time."
The rest of Daniel chapter 12 includes..."It will be for an appointed time, appointed times, and half a time. As soon as the dashing to pieces of the power of the holy people comes to an end, all these things will come to their finish." Three and a half years.
And..."“And from the time that the constant feature has been removed and the disgusting thing that causes desolation has been put in place, there will be 1,290 days."
The parallel visions of the march of certain world powers in Daniel chapters 2, 7, and 8 show that we are coming to the time discussed in Daniel chapter 11/12.
It is during the time we are in right now that Jesus will take the throne in heaven. We don't know the day or the hour, but when it happens the Devil will be cast down, the UN riled up, religious institutions attacked, 3 1/2 years of tribulation, etc.
