From the abomination of desolation/image of beast to the Return of Jesus Christ to the Earth, there are 1,290 days (43 biblical months since a biblical month is 30 days long and 1290 days divided by 30 days per biblical month = 43 biblical months):

Daniel 12:11 1611 KJB
11 And from the time that the dayly sacrifice shalbe taken away, and the abomination that maketh desolate set vp, there shalbe a thousand two hundred and ninetie dayes.

Also note that the Antichrist's consquest+overruning of Jersualem and the modern counterfeit "Israel" state, the False Prophet/2nd Beast's lying signs and wonders, the making and setting up of the abomination of desolation, and the sacrifice in the Antichrist's Temple, ALL occur on the same day of when the Antichrist and the world's armies overrun Jerusalem & the entire modern counterfiet state of Israel (aka God called this the days of vengance as his punishment on that place) and then makes Jerusalem desolate immediately (right after he overruns Jerusalem) by means of the false prophet convincing the world's nations to make the Image of the Beast and to set up the Image of the Beast/the Abomination of Desolation in Jerusalem inside of the Antichrist's Temple (note the words" then know that the desolation thereof is nigh." in Luke 21 and compare ):

Matthew 24:14-16 1611 KJB
14 And this Gospell of the kingdome shall be preached in all the world, for a witnesse vnto al nations, and then shall the end come.
15 When yee therefore shall see the abomination of desolation, spoken of by Daniel the Prophet, stand in the holy place, (who so readeth, let him vnderstand.)
16 Then let them which be in Iudea, flee into the mountaines.

Luke 24:20-24 1611 KJB
20 And when yee shall see Hierusalem compassed with armies, then know that the desolation thereof is nigh.
21 Then let them which are in Iudea, flee to the mountaines, and let them which are in the midst of it, depart out, and let not them that are in the countreys, enter thereinto.
22 For these be the dayes of vengeance, that all things which are written may be fulfilled.
23 But woe vnto them that are with childe, and to them that giue sucke in those dayes, for there shalbe great distresse in the land, and wrath vpon this people.
24 And they shall fall by the edge of the sword, and shall bee led away captiue into all nations, and Hierusalem shall be troden downe of the Gentiles, vntill the times of the Gentiles bee fulfilled.

Revelation 13:13-15 1611 KJB
13 And hee doeth great wonders, so that hee maketh fire come downe from heauen on the earth in the sight of men,
14 And deceiueth them that dwel on the earth, by the meanes of those miracles which he had power to do in the sight of the beast, saying to them that dwell on the earth, that they should make an Image to the beast which had the wound by a sword, and did liue.
15 And he had power to giue life vnto the Image of the beast, that the Image of the beast should both speake, and cause that as many as would not worship the Image of the beast, should be killed.

Daniel 7:41 1611 KJB
41 He shall enter also into the glorious land, and many countreys shall be ouerthrowen: but these shall escape out of his hand, euen Edom, and Moab, and the chiefe of the children of Ammon.
