Though I would never stir a pin of the historic prophetic licence of a day for a year application of the 2300 days, there are views that repeat the 2300 day prophecy literally at the end-time.
This prophecy was given in the third year of the Babylonian king Belshazzar, about 553 BC, which was some 15 years before the 70 weeks prophecy of Daniel 9. So those who maintain that the 2300 day prophecy is inseparable with the 70 weeks prophecy may be at issue.
See this explanation at the following link. I do not agree that the prophecy of Daniel about 553 BC equalled a literal day only, but the rest of the statement explains a good reason for a literal day fulfillment at the end-time.
The 2300 day Prophecy of Daniel 8
1. This prophecy was given in the third year of the Babylonian king Belshazzar, about 553 BC, which was some 15 years before the 70 weeks prophecy of Daniel 9.
2. In this prophecy a day equals one day of 24 hours, not one ordinary year.
3. This prophecy concerns the 2300 day defilement of the heavenly sanctuary by the 'little horn' (the Beast, the Antichrist) who will dare to challenge the angelic host above and cast some of them down to earth. The Antichrist even challenges the 'Prince of the heavenly host' (Yeshua the Messiah). A more blasphemous move is hard to imagine.
1. As pointed out above, the 2300 day prophecy is scheduled for fulfilment many years after it was given. It would come to pass at 'the appointed time of the end.' We are not told the starting year, but we are told that the central character is the little horn power (the Antichrist); and we know that he is scheduled to make his appearance just before Jesus Christ returns.
2. Like the prophecy recorded in Daniel 7, this prophecy tells of the death of the 'little horn' power at the second coming of Jesus Christ. He is to be 'broken without hand.' That is, he will be supernaturally destroyed by the word of the 'Prince of princes' (Jesus Christ) at his return. These are vital clues, because they point to our immediate future.
