Matt 24
14 ""This gospel of the kingdom shall be preached in the whole world as a testimony to all the nations, and then the end will come.
Not until the Gospel has gone into the entire world - will Christ come - and this was spoken by Christ pre-cross and then published by Matt post-cross - as a "future event". The Gospel going into all the world - an event we "Still" wait for.. This scope applies to “all mankind” not just Jews.
Matt 24
15 ""Therefore when you see the ABOMINATION OF DESOLATION which was spoken of through Daniel the prophet, standing in the holy place ( let the reader understand),
16 then those who are in Judea must flee to the mountains;
17 Whoever is on the housetop must not go down to get the things out that are in his house.
18 Whoever is in the field must not turn back to get his cloak.
19 ""But woe to those who are pregnant and to those who are nursing babies in those days!
20 ""But pray that your flight will not be in the winter, or on a Sabbath.
Where was “the holy place” in the days of Christ – was it outside of the city in the burial grounds?
Jer 31
38 ""Behold, days are coming,'' declares the LORD, ""when the city will be rebuilt for the LORD from the Tower of Hananel to the Corner Gate.
39 ""The measuring line will go out farther straight ahead to the hill Gareb; then it will turn to Goah.
40 ""And the whole valley of the dead bodies and of the ashes, and all the fields as far as the brook Kidron, to the corner of the Horse Gate toward the east, shall be holy to the LORD; it will not be plucked up or overthrown anymore forever.''
Matt 24
21 For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will.
22 ""Unless those days had been cut short, no life would have been saved; but for the sake of the elect those days will be cut short.
The persecution of Christians by the Pagan Roman empire - and then persecution of Christians by the Holy Roman Empire - "The Dark Ages" - represents centuries of killing Christians - unprecidented in extent and length of time - in all of history.
This non-SDA link shows a chronology of the Matt 24 events that DOES have the 1260 years of the dark ages matched with the expected tribulation mentioned in Matt 24.

Matt 24:
23 "" Then if anyone says to you, "Behold, here is the Christ,' or " There He is,' do not believe him.
24 ""For false Christs and false prophets will arise and will show great signs and wonders, so as to mislead, if possible, even the elect.
25 ""Behold, I have told you in advance.
26 ""So if they say to you, "Behold, He is in the wilderness,' do not go out, or, "Behold, He is in the inner rooms,' do not believe them.
27 "" For just as the lightning comes from the east and flashes even to the west, so will the coming of the Son of Man be.
The visibility of cloud-to-could lightning - from one end of heaven to the other - is the "comparison" made with the 2nd coming.
The coming is in the clouds - just as the lightning and just as the "signs".
Matt 24:
29 ""But immediately after the tribulation of those days THE SUN WILL BE DARKENED, AND THE MOON WILL NOT GIVE ITS LIGHT, AND THE STARS WILL FALL from the sky, and the powers of the heavens will be shaken.
These Matt 24 events are recorded in the encyclopedia. First we note that the 1260 years of the dark ages ends in the 1700's. Then we notice the Lisbon earthquake, 1755, the dark day in the Northwestern US, 1780, and the "falling" of the stars, 1833 – all follow the end of that tribulation period.
Historically this is known as “the Dark Day”. It was not world wide but it was recorded here.
The remarkable Dark Day of May 19, 1780, is described by Samuel Williams of Harvard, The professor relates... "between the hours of ten and eleven a.m., and continued until the middle of the next night,... Candles were lighted up in houses; ... the birds having sung their evening songs, disappeared, and became silent;... the fowls retired to roost; ... the cocks were crowing all around, as at the break of day; ... objects could not be distinguished but at a very little distance; and everything bore the appearance and gloom of night." -Memoirs of the American Academy of Arts and Sciences [through 1783], vol.1 pp. 234,235.)”
