We will not know, that is true. But we were told we'd know it is near from the signs of the times and to be ready. Jesus tells us this. Read Matthew 24. I'll share parts of it.

And Jesus answered and said to them: “Take heed that no one deceives you. 5 For many will come in My name, saying, ‘I am the Christ,’ and will deceive many. 6 And you will hear of wars and rumors of wars. See that you are not troubled; for [a]all these things must come to pass, but the end is not yet. 7 For nation will rise against nation, and kingdom against kingdom. And there will be famines, [b]pestilences, and earthquakes in various places. 8 All these are the beginning of sorrows.

9 “Then they will deliver you up to tribulation and kill you, and you will be hated by all nations for My name’s sake. 10 And then many will be offended, will betray one another, and will hate one another. 11 Then many false prophets will rise up and deceive many. 12 And because lawlessness will abound, the love of many will grow cold. 13 But he who endures to the end shall be saved. 14 And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come.

32 “Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer is near. 33 So you also, when you see all these things, know that [e]it is near—at the doors! 34 Assuredly, I say to you, this generation will by no means pass away till all these things take place. 35 Heaven and earth will pass away, but My words will by no means pass away.

36 “But of that day and hour no one knows, not even the angels of [f]heaven, but My Father only. 37 But as the days of Noah were, so also will the coming of the Son of Man be. 38 For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, 39 and did not know until the flood came and took them all away, so also will the coming of the Son of Man be. 40 Then two men will be in the field: one will be taken and the other left. 41 Two women will be grinding at the mill: one will be taken and the other left. 42 Watch therefore, for you do not know what [g]hour your Lord is coming. 43 But know this, that if the master of the house had known what [h]hour the thief would come, he would have watched and not allowed his house to be broken into. 44 Therefore you also be ready, for the Son of Man is coming at an hour you do not expect.

I think there is a group of people out there right now who are trying to make it look like the end times.

But where is the line when all of what is happening is actually what God wants to happen and is making happen that way? God puts it in their minds after-all to do such things.

Revelation 17:12-14

“The ten horns which you saw are ten kings who have received no kingdom as yet, but they receive authority for one hour as kings with the beast. These are of one mind, and they will give their power and authority to the beast. These will make war with the Lamb, and the Lamb will overcome them, for He is Lord of lords and King of kings; and those who are with Him are called, chosen, and faithful.”

Revelation 17:17

For God has put it into their hearts to fulfill His purpose, to be of one mind, and to give their kingdom to the beast, until the words of God are fulfilled.
