I consider that the feet and toes continue on until the return of Jesus to establish his Kingdom upon the earth Daniel 2:35,44. Jesus as the stone will smash into the feet when he comes, and as such the feet and toes must reach beyond AD 476, and last until 2022++, whenever Jesus returns (soon).
I believe Jesus as the stone (through the Church) smashed the image during the time of the feet (when the Roman Empire was in two parts), which occurs before the time of toes (when the Roman Empire had broken up into ten kingdoms).
In other words, Nebuchadnezzar’s image was a prophecy of Christianity conquering Paganism
in the fourth century. The time of the toes wasn’t until the fifth century.
Also you do not give an indication of when the 2300 starts and terminates. I suggest a major fulfillment was from BC 334-333 to AD 1967.
I believe the prophecy of Daniel 9 was given to explain the ending of the vision of Daniel 8
. So the two highlighted texts below are the same event...
Daniel 8:25... And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes
; but he shall be broken without hand.
Daniel 9:26... 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 thereof shall be with a flood, and unto the end of the war desolations are determined.
So I believe the vision of Daniel 8 (the 2300) starts at the Tower of Babel
, the prophecy of Daniel 9 (the 490) starts in 458/457 BC, and they both end by the Fall of Jerusalem.
Another aspect is that I believe that the 1260 years has mainly two starting dates, Justinian AD 529-533, Phocas AD 610, terminating respectively AD 1789-1793 The French Revolution and AD 1870 the loss of the Papal States and associated problems.
The Papacy is a unique entity where the Pope is both a spiritual leader and also a temporal leader (a king).
I date the beginning of the Papacy’s spiritual reign to Phocas AD 610, but I date the Papacy’s temporal reign (the 1260) to the Pope crowning the Emperor in AD 800
