Exact Date Of The Great Day of the Lord

What is the exact date of the great day of the Lord?

Isaiah 66:15,16 15 For, behold, the Lord will come with fire, and his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire. 16 For by fire will the LORD, and by his sword, to all the people: and the slain of the Lord shall be many.

(Fire and sword, the word of God Revelation 19:15)

Jeremiah 25:32,33 32 Thus saith the Lord of hosts, Behold, evil shall go from nation to nation, and a great whirlwind shall be raised up from the uttermost parts of the earth. 33 And the slain of the Lord shall be at that day from one end of the earth even unto the other end of the earth: they shall not be lamented, neither gathered, nor buried: they shall be dung upon the ground.

How many  the Lord will slain? In the book of Revelation we can read in chapter 9 verse 15 and 19,  large number will be killed, 1/3 of mankind.

Rev. 9:14,15 14 Saying to the sixth angel who had the trumpet, Loose the four angels who are bound at the great river Euphrates. 15 And the four angels, to be fitted in the hours and days and months and years to slay the third part of men. 18 By these three plagues was the third part of the people, by the fire and the smoke and the brimstone, which issued out of their mouths.

Check us out if that happen near river Euphrates.

Jeremiah 46:10 For the day is with the Lord, the Lord of hosts, a day of vengeance, that he may avenge him of his adversaries: and the sword shall devour and be satiate, and shall their blood: because the Lord, the Lord of hosts hath a sacrifice in the north country by the river Euphrates.

Is there great a ricer located next to the Vatican? I do not know. But I believe it was not in the Vatican. According to Jeremiah 46:10, the day of vengeance, that day, and the day is the day of the Lord. So, the day, hour, month and year (Revelation 9:15) will occur the day of the Lord. When will the day of vengeance be, according to Lord Jesus?

Luke 21:20-22 20 But when ye surrounded by the army of Jerusalem, then know that the desolation thereof is nigh. 21 Then those in Judea flee to the mountains, and in the midst of it depart out: and let not enter the city. 22 For these are days of vengeance, that all things which are written.

More paragraphs can be match here but maybe this is enough.

In addition:
The Euphrates River is located next to Babylon (present Iraq)

What happens when Jerusalem was besieged by the army?

Luke 19:41,42,43,44
41 And when he came near him, he saw the city and wept over it, 42 Saying, If today you would have known it, to yourself, the things which belong unto thy peace! But now they are hid from your eyes. 43 For it will come to you the day you that thine enemies fortress and besiege thee, and keep thee in on every side, 44 And shall lay thee even with the ground, and thy children within thee: and in They never leave thee a stone upon a stone: because thou hast not known the time of thy visitation.

Jerusalem and Babylon are the same, because they written in same symbol of prophecy to keep the mystery secret and be revealed at the appointed time.

Matthew 23:35-39 35 That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias you murdered between the sanctuary and the altar. 36 Verily I say unto you, All these things shall come upon this generation. 37 O Jerusalem, Jerusalem, who kills the prophets and stones those who are sent to her! how often would I have gathered your children together, as a hen gathering her chicks under her wings, and ye would not! 38 Behold, your house is left unto you desolate. 39 For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.

Rev 18:24 And in her was found the blood of prophets, and of saints, and of all those killed on the ground.

Based on Revelation 9:15, 1/3 or the third part of mankind will be killed. It is also called the "day of slaughter"

Jeremiah 25:30-34
30 Therefore prophesy thou against them all these words, and say unto them, The LORD shall roar from on high, and utter his voice from his holy habitation; him roar aloud against his fold, he shout, as they that tread the grapes, against all the inhabitants of the earth.
31 The noise was coming to the end of the earth: for the LORD hath a controversy with the nations, he will plead with all flesh concerning the wicked, he will give them to the sword, saith the Lord.
32 Thus saith the Lord of hosts, Behold, evil shall go from nation to nation, and a great whirlwind shall be raised up from the uttermost parts of the earth.
33 And the slain of the Lord shall be at that day from one end of the earth even unto the other end of the earth: they shall not be lamented, neither gathered, nor buried: they shall be dung upon the ground.
