This is not necessarily prophetic. This is about punishment that God places on people for disobedience or lack of faith.
Some apply that to prophecy.
Even the 70 years in captivity was a punishment on the southern kingdom.
The 70 weeks may have been a direct relation to the 70 years, or just God working in His own time frame. 490 years is still short of 500 years which is half a time to God.
I think most would agree that Daniel lived 500 years before the earthly ministry of Jesus.
Times, time, and half a time is 3500 years. That is good enough for me. Placing 2300 years or anything else, into history is just date setting. Many want to date set, and interpret the 70 weeks into their comfortable human dates from history.
Daniel said that Nebuchadnezzar lived as a wild animal "until seven times will pass over thee".
KJV Daniel 4:32
32 And they shall drive thee from men, and thy dwelling shall be with the beasts of the field: they shall make thee to eat grass as oxen,
and seven times shall pass over thee, until thou know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will.
Seven years.
Times, time, and half a time is 3 and a half
prophetic symbolic years. Daniel 12:7 and Daniel 7:25 speak of the same power. That same power is also referred to in Revelation 13:5, and 11:2. That power is papal Rome. The same time period is measured against the time God's people were persecuted by that power. You will find that in Revelation 11:3, 12:6, and 12:14. That period ran from 538AD to effectiv 1798AD. 538AD was the year Justinian's decree to give the Pope official authority (see Revelation 13:2) over other bishops was made effective through the decisive battle of Rome when Belisarius ousted the Goths who were inhibiting the bishop of Rome from exercising autonomy and authority. In 1798 Napoleon's general Berthier entered Rome, placed the Pope under arrest who subsequently died in exile, disbanded the college of Cardinals, declared the papal states a republic, and effectively dismantled the political power and authority of the Roman bishop over secular nations. Her tenure as a union of church and state came to a brief end. This was the head that "as it were was wounded to death". That wound is now healing, quickly. Starting in 1928 when Mussolini reinstated the Catholic Bishop as a political power in the Vatican. His power has since grown exponentially. But ironically, it won't be Rome that enforces the mark of its own authority. That pleasure behind to the false prophet, the second beast of Revelation 13. Protestant America.
BTW. All those time periods are symbolic, just as the rest of the prophecy is symbolic imagery. 1260 days....3 and a half years...42 months... Times, time and a half; all 1260 prophetic symbolic days which equal literal years. A day for a year. There are several confirmed applications where fulfillment meet the prophetic time period. One example is the prophecy of Jesus in His letter to the church of Smyrna. He said, "you shall have tribulation 10 days". All the letters have applications to local literal churches, but are also applicable to historic iris of time from the time of John to the second coming. Smyrna's time team from roughly 100AD to 323AD. Diocletian ruled during a party of that period, and was known to have brought great tribulation upon the church for 10 years.
