Biblical prophecies can have numerous fulfillments.
Don't forget,
Jesus mentions Daniel in His famous 1st century 70ad Olivet Discourse.
Some consider the "rapture" was the fleeing of Christian Jews from Judea before Rome sieged it.
Will that event be repeated upon the Jews and Jerusalem in the future is anyone's guess.?
The Sanctuary mentioned in Dan 8 is also mentioned in Reve 11:2 and mirrors Luke 21:20
Luke 21:20 “But when you see Jerusalem surrounded by armies, then know that its desolation has come near. 24 “And they will fall by the edge of the sword, and be led away captive into all nations. [Revelation 13:10]
And Jerusalem will be trampled<3961> by Gentiles until the times of the Gentiles are fulfilled.” [Revelation 11:2]
=====================
Some believe this is speaking of Herods's rebuilt Temple, but that is for a different topic:
Revelation 11:2 and the Court without of the
Sanctuary, be Casting-Out! out-side, and no it thou should be measuring, that it was given to the Nations
and they shall be trampling<3961> the holy City forty two months. [Luke 21:20]
========================
A day for year is not mentioned as in some other OT passages [
Numbers 14:34 Ezekiel 4:6]
Best to look at numerous translations and commentaries on it.
Here are some commentaries on it and I will only mention the "Pulpit":
Daniel 8:13 Commentaries:
Pulpit Commentary
Daniel 8:13 Verse 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?
We would render the speech of the angel, "How long - the vision, the sacrifice - the sin of desolation to give the sanctuary and the service to be trodden underfoot?" as if Daniel had only heard snatches of what was said; we would, we may say, omit the "and" before "sanctuary." The Septuagint translators may have omitted צָבָא (tzaba), thinking only of its ordinary meaning, "host," forgetful of the fact that it is used of the temple service in
Numbers 4:23. These angels are most interested in the length of time that the sanctuary shall remain desolate.
======================
And one on vs 14.
Daniel 8:14 Commentaries:
Pulpit Commentary
Verse 14. - And he said unto me, Unto
two thousand and three hundred days; then shall the sanctuary be cleansed.
The Massoretic reading is here clearly corrupt. "Unto me" ought to be "unto him," as proved by the versions and necessitated by sense. The LXX. is somewhat violent in construction, but means, "And he said to him, Until evenings and mornings are two thousand three hundred days, and the sanctuary shall be purified." Theodotion agrees closely with the LXX., only he has "five hundred" instead of "three hundred.
=====================
According to Josephus,
the Jewish Rebellion began in 66 ad and ended with the destruction of Jerusalem and the Temple in 70AD after about a 5 month siege.
The Destruction of Jerusalem - George Peter Holford, 1805AD

Theodotion agrees closely with the LXX., only he has "five hundred" instead of "three hundred." The Peshitta agrees with the Massoretic, save as above mentioned - "him" instead of "me," and the last clause, which ought naturally to rendered "and the sacrifice be purified."
=========================================
It took about 5 months or 150 days to conquer Jerusalem.
This memorable siege terminated on the eighth day of the ninth month, A. D. 70 : its duration was
nearly five months, the Romans having invested the city on the fourteenth day of the fourth month, preceeding.
